Conclusions 1.The mechanical characteristics are given for steel 4Kh12N8G8MFB at temperatures of +20°, -78, -196, and -253° after heating at 1100°C with holding for 1.5 h and quenching in water.2.Low-temperature plastic deformation by elongation increases the strength of steels 1Kh18N9T and 4Kh12N8G8MFB. At the same degree of deformation, the strength of steel 1Kh18N9T increases more than that of 4Kh12N8G8MFB.3.With an incrase of the quenching temperature from 950 to 1150° for steel 1Kh18N9T and from 1000 to 1200 for steel 4Kh12N8G8MFB the stability of austenite increases, and consequently the ??a transformation is delayed in subsequent low-temperature deformation. |
