/~E1STiiACT: ~'hle creation of sharp strQ,s ron~ntrators is sometimes unavoidable ;n
the design of machine parts. i:or this reason, the study of fatigue strength in
steel specimens having notches with a theoretical coefficient of stress concen-
tratiGn (Kt} greater than 3 acquires practical importance. The present paper
deals with the cyclic bending strength of cylindrical specimens of low�stsrength
steel 3 anti high-strength sisal 30KhGSA it the presence of circular groovas~having
bottom radii of 0.42-0.$0 mm (values of Kt frrxn 1.8 to 14.5). The results show
that the fatigue strength decreases with an increase in the sharpness of the notch,
up to a certain limit (the critical notch radius), after which it remains con-
i scant. The critical notch radius thus corresponds to a Limiting minimal cyclic
?Cordre~~~h' which is of practical significance since further work ma

deformation whzch indicated that, under the experimental conditions
employed, creep is associated mainly frith intercrystalline slip with
very little deformation taking place within the grains.
{3) The total elongation depended upon the applied stress and
varied between 17.5 and 25io in steel EKh18N9 and between 8 and 16/
in steel 41~h14N14V2M. This difference was attributed to the
larger grain-size of the latter material.
(4) For an equal sttress of 2.5 kg/mm2, the time-to-rupture was
5.5 and 24 minutes on steels EICh18N9 and 4Kh14N14V2M respectively.
This difference was also attributed t~ the difference in the
grain-size, since the total length of the grain boundaries which
determine the strain accumulated prior �o fracture is smaller in a
coarse-grained material. fihere are 9 figui�es and 3 Soviet-bloc
references.
