摘要：
We worked out a regime of high-temperature thermoplastic treatment of steels St3sp and 09G2S consisting in austenization at 1020°C, strain (ε∑=200%, ε=5.7%) at 940°C with subsequent cooling at a rate >100°C/sec. As a result of such treatment the tensile strength of steel St3sp is increased to 1230 N/mm2, of steel 09G2S to 960 N/mm2, and the conventional yield strength to 1100 and 840 N/mm2, respectively. © 1992 Plenum Publishing Corporation.
