Abstract

The results of impact bending tests of 22K steel before and after long-term heat treatment provoking temper brittleness are presented, serial curves are plotted, the fracture surfaces after the tests are analyzed. The heat treatment of 22K steel, which provokes temper brittleness, is shown to cause a decrease in the ductile–brittle transition temperature by 30–40°C.

长期退火对22K钢冲击韧性的影响

摘要

给出了22K钢在长期热处理前后会引起回火脆性的冲击弯曲试验结果，绘制了系列曲线，分析了试验后的断裂面。22K钢的热处理会引起回火脆性，事实表明，这种处理会导致韧性-脆性转变温度降低30-40°C。
