摘要
对国产、进口两种牌号的３．５Ｎｉ钢板进行了模拟热成形加热试验以及热成形后的正火加回火热处理试验。试验结果表明，热成形过程会大大削弱钢板的低温韧性，正火加回火热处理是恢复钢板低温韧性的一个非常有效而又十分必要的手段。
Abstract The mechanical properties of two brand 3 5Ni steel plates were tested after the simulated heating for hot forming,and the heat treatment experiments of normalizing plus tempering after the simulated heating were also carried out.The results show that the low temperature toughness of the steel plates is greatly weakened by the hot forming process.It is necessary for normalizing plus tempering to recover the low temperature toughness effectively after hot forming.
