Portions of the strip bent into a circular sj~iape were inserted in to steel rings of various diameters (the stresses in the strip,4 Iid i7 not exceed the elastic limit). After soaking at j certain tempeia- ture followed by a period of cooling, the strips were removed. The magnitude of "relieved" stresses was ~deterr*nined from. the: curvature of the strip. The intensity of stress reduction increised with increasing temperatures and increased with increasing mag- nitude of the initial stress. At a temperature of 5500C, the Card 112 stresses were relieved completely by the rnechanism of rel'axat !ion.

The steels were austenitized atAjOOIIC~for 3 min..'Coba.1t with or without other alloying elements decreased the stability ot aus-tenite in ~Ilsub,- critical temperature intervals. Intermediate transfomatib~s occUrred in all, steels. Cobalt promoted the formation of a thin ferrite-carbide mixture w1th a high,degree of hardness. Depending on the austenitic transformation temperature.in the subcoitical region, different methods could be developed for forming a definite type of structure having particular properties: a) sorbite at transformation~t.emperatures of 550-6.500c; UDC: 669.15-194:669.t5t620.181 L.~ard 1/2 ACC NRi AP6023046 b) a mixture-of trootsite and bainite at 450-5000C; and c) bainite at temperatures be- low 40010C.ItHicrostructures of each of the above transformation products were shown. The hardnesses of trans?6i;Wation products formed at 4001-6000C are given for16 of the steels. The hardness change as a function of transformation~tlme went through a maxi- mum at 0.5 min for transformation temperatures of 4000 450 and 5000C. This was ex- plained by the diffusion decomposition of supersaturated ferrite; -the decomposed car- bon entered the untransformed austenite which gave off-tarbides. This also 'accounted for the lower hardness of martensite formed during subsequent quenching.~ OrIg. art. has: 3 figures, 2 tables. SUB CODE: ll/ SUBM DATEi 26Mar65/ ORIG REFt~ 002/*.
