TEXT: The influence of Al addition in the range 0f'2-35 - 4.67 %
and of 0 in the range of 0.1 - 0.8 % was investigated in 10 % Or,
and 13 % Mn steel in which the appearance of the cr-p'hase is ex'clu-
ded. The samples were prepared by smelting in a'magneaite crucible,
in an induction furnacep and consisted of Armco~iron, Crp Mn~(96.i5%
pure) and Al metal. C was introduced by addition of synthetic cast
iron. The ingots were forged into cylinders of '12 and 20 mm diame..
ter,,,-,,starting the forging at 11500 - 12000C evding at 7500C~ The'.,
samples were then hardened by quenching in water from 9500C for 2,

temperature range, The austenite of the 10 % Cr,,13 % Kri and 00 %C
steel is unstable and is transformed'into martenbite under the'ac-;.
tion of plastic deformation. Aluminum exerts a high ferrite-forming
action and lowers the high-resistance characteristics . Exploiting
