whelps were obtained; when feeding reduced rations (550
large calories) during the first half of the pregnancy and
increased rations (700 large calories) during the second
half of the pregnancy, the litters averaged 3.3 whelps per

-The specific rate for dissolvi4g of cast iron in an aluminum alloy with 14 Zn

increase in temperature from 680-690 to 720-7300C has no effect on specific rate'

content in the melt and at a concentration of 28% the rate i3'the same as for

The specific rate of dissolution for iron in this alloy-is also very low and
increases somewhat with an inoreas* in inn concentration in the alloy, Low
iron saturation intensity in a Zn+0.2%Al alloy is due to the low calorizing
temperature. Thus, the bath is quite highly saturated with iron during

In the aluminizing of Armco iron in pure aluminum, the diffusion
layer consisted of two zones: a thick zone of cal"nar crystallites a440'jm-:
ing the iron, and, considerably thicker. a fine crystalline zone (2-3
.microns) adjoining the aluminum. The columnar crystallites grew pre4ami-'
nantly in a direction perpendicular to the front of the reactive diffusion
(toward the specimen surface) with the formation of characteristic protu-'
sions ~-- tongues.
Formation of the two-phase layer is the result of reactive diffusion
in the solid iron - aluminum melt systems the diffusion of aluminum atoms
promotes the growth of columnar crystallites and the overall thickness of
the layer, and in the straightforward diffusion of iron, atoms change in
the condition of equilibrium of the system which leads to a decrease in
layer thickness. From the thermodynamic point of view, this phenomenon
boils down to an increase.in entropy of displacement and decrease in the
free energy of the system and, therefore, proceeds spontaneously and irre-
versibly.

structure of the alloy is analyzed. It is shown that both transition and nontran-
is.sition metals conform to the Seger rule on high energies for packing defects in
metals. The twinning * slipping transition in alloys of transition metals is stud-:
ied. All alloys of elements in group VIA with metals in groups VIIA and VIIIA show
a transition to twinning, while alloys with elements in group VIA (Mo-Ti alloys) ,
show no twinning throughout the entire region of solid solutions with a bcc lattice,
under maximum loads. Experimental data show that alloying chromium, molybdenum and
tungsten with metals of groups VIIA and VIII reduces the packing flaw energy and
causes a transition.to deformation by twinning (or to combined deformation by
slipping. and twiUni.ng). A. brief survey of the literature shows no transition to
twinning in alloys of- group VIA with transition metals to the left of the chromium

ABSTRACT:' The article deals with the refining of chromium by treatment with highly active
elqments which react with the interstitial impurities in Cr to form more stable compounds
thaA the corresponding Cr compounds. To this end, the use of Y and other rare-earth elements
is particularly promising since then it is often possible to im~~e~bt only the plasticity but V
also' the high temperature strength of the alloy. However, there is no common consensus on
this effect of Y and rare-earth elements. Thus, 0. N. Carlson et al. (Less Ckrmmon Metals,
l&, 6, 6. 439) present experimental findings indicating that the temperature of cold brittle-

ness of cast Cr increases when It is treated with Y and oUier rare-ldrth elements. To clear
up this contradiction, specimens of Cr treated with Y as well as oflure Cr in soldered and
evacuated ampoules were annealed at 1200*C for 1 hr and water-quenched. By means of Vickers
hardness tests, aging of these specimens was Investigated at three temperatures (275% 350*
and 4000C) in a molten-tin bath. The findings on the Increase in rrdcrohardness with aging are

hence also it suppresses the rise In the temperature of cold brittlene;d ue to the segregation
of an Interstitial impurity -- nitrogen -- from the solid solution). These findings confirm the
feasibility of using Y to improve the refining of Cr, since Y binds the greater part of nitrogen
into nitrides, thus suppressing most of the effects of aging. Further tests, involving the
treatment of Cr with microamounts of Y and Pr over a broad temperature ringe: from the

ABSTRACT: microscopy was used to study deformation and crack formation in
thin chromium foils. The chromium foils were made from ingots which wiare arc melted
in argon. Circular, self-supporting samples were made from discs which were gradually
thinned toward the center (thinnest section),.and cracks were induced at the center by
pricking the disc near the edge. This method allowed various stages of deformation as
well as crack formation to be studied. An electron micrograph showed slip traces caus-
ed by the intersection of mobile dislocations with the oxide layer formed by electron
bombardment. These slip traces were identified with surface interactions. Disloca-
tions accumulated in the slip planes along the boundaries of the foil as a result of
retarded motion. Three slip planes were observed: {110), (112), and (123). Aging
the foils at room temperature or heating to 3500C in the microscope column did not af-

fect the microstructures. Electron micrographs were,also given of fractured center
sections of the sample disc. Both intercrystalline and transcrystalline cracks form-
ed. Cracks along grain boundaries did not result in much plastic deformation in neigh-
boring areas. It was hypothesized that these were caused by dislocations moving at
stresses below the elastic limit of the material, accumulating in grain boundaries,
and nucleating as cracks at well below the elastic limit. Interactions of transcrys-
talline cracks with grain boundaries also occurred. qracks penetrating into the thick-
er sections of the foil were bent at the point where,the crack stopped propagating.
This region showed heavy plastic deformation. The slip plane reactions-necessary to
form cracks (Cottrell mechanism) were outlined by slip traces in the foil which ad-
joined the crack edges. Slip planes and directions were given for microcrack nuclea-
tion in the foils. The microcracks.lay along the (112) plane and did not have the
orientations necessitated by the Cottrell mechanism. In utilizing there results in
foils it is necessary to consider the details of deformation in foils, particularly
the stress state and surface effects. Orig. art. h": 5 figures, 1 table, 1 formula.

Experiments in dogs showed that intravenous transfusion may be giverl much more
rapidly than has hitherto been routine, and that it is the addition of sodium ciirate
to the donor blood which has been the cause of overstrain and heart failure. The
rate of transfusion of hepa r inized blood may be adjusted to the requirements of tile
organism involved. Further experiments showed that the ill-effects cziused by
transfusion of citrate blood may be controlled by addition of calcium gluconate
and procaine. The rate of transfusion and the effect of sodium citrate and calcium
gluconate may be determined by registration of the venous blood pres~;Ure, the
physiological initial value of which should not be exceeded during transfusion.
Findings show that intravenous transfusion may be carried out considerably more
swiftly than intra- arterial transfusion, so that the latter would seem to be super-

The authors -investigated the mechanism of cardiac overloading and failure frequent-
ly observed In rapid Intravenous transfusions. In experiments on dogs, a rate of
transfusion of heparinized blood of 6 mi./kg./min. was given with no ill-effects;
however, citrated blood transfusions. produced certain haemodynamic disturbances.
Sma1I intravenous doses of cLtrate administered to dogs revealed a marked vaso-
constriction in the pulmonary network that produces a strain on the right ventricle.
In high concentrations, it weakens cardiac action by direct action on the myocardi-
um. From these experiments it is concluded that it is the sodium citrate and not
the blood itself which is the cause of cardiac overloading and failure in rapid i'ltra-
venous transfusions. Since it is. not poEsible to'use hepa rinized blood in clinica.1
practice, the rapid Intravenous transfusion of citrated blood Is administered simul-
taneously with calcium gluconate and procaine. These drugs counteract the un-
favourable effect of sodium citrate as reflected by the results of its use clinically
for 2 yr. Hale - Cleveland, 0, (IX, 61,

Judging from experiments on more than 50D dogs and clinical trials extending wier
3 yr., failures are of 3 kinds. In the largest group the rate and amount of blood
transfused were insufficient. In a smaller group the amount and rate seem suffici-
ent but the patient deteriorates with continuing transfusions. Most of these failures
are a result of the grave initial state of the patient - particularly severe shock and
irreversible changes. In the smallest group the rate and amount of transfused
blood, otherwise corresponding to the patient's needs. induce cardiac failure.
Recognition of the 3rd group led to great caution in giving rapid transfusions.
Overloading and failure of the heart during rapid transfusions Is not a function of
transfusion per se but of the amount of citrate given. Even in small doses citrate
produces vasoconstriction in the pulmonary vascular bed, and in larger doses de-
presses myocardial activity, both effects leading to cardiac overloading and failure.
The effect of citrate during transfusion can be safely counteracted by the simul-
taneous i.v. administration of calcium and procaine. Bruusgaard - Oslo (IX, 19)

PERIODICAL: Aplikace matematiky, v. 6, no. 2, 1961, 91-99
TEXT-. For investigating the limiting stresses of building struc-
tures and for calculating auto-vibrational frequencies of systems
in unstressed conditions, as well as of systems under static axial
stresses, the most frequently employed methods include the deforma-
tional and vectorial ones and the integration of differential equa-
tions, Ritz's and Galerkin's methods. In these methods one encoun-
ters the problem of evaluating the ordinate value E of a homogenous
system of n algebraic- equations, which are linear Klative to the
unknown xi at i - 1,2,...n. Such a homogenous system is presented

The main advantage.in this procedure is that it dispenses with the
platting of the function 6(F-) in a graph for interpolation. The
proposed method divides each of the system (1) equations by xn / 0,

The first method is itsed for determination of the characteristic
frequencies of a fraim-,work, (PIg. 1). The root ?Lo is obtained as the

The third system, the system of double iteration, is based on pre-
vious work by the author (Ref. 1: kplikace matematiky, no. 2, 1961)
and is actually a combination of the method of the normal iteration
and the cited work by the author. The last method, that of treble
iteration, is also based on the author's previous work, forming ap-
proximations of approximations for the characteristic roots. Nume-
rical examples are given. The conditions of convergence of the me-
thods are not examined. Exact and appropriate calculation of the
first derivative of function (7) Is given; four approximate equa-
tions for this function in the neighborhood of point A (k) are al-
so given. There are 3 figures, 1 table and 9 referenc6s: 8 Soviet-
bloc and 1 non-Soviet-bloc.
