摘要
应用Ｆｏｒｍａｓｔｏｒ－Ｄｉｇｉｔａｌ全自动相变测量仪，测定了Ｓ７钢的ＴＴＴ曲线。研究了该钢不同参数的退火工艺，并提出了该钢最佳退火工艺。
By investigating TTT diagram of S7 steel by means of fullautomatic transtormation testing instrumtnt(Formastor-Digital ) and by strdying snnealing technology at diffenrent parameters, according to the resulte ,the best annealing tenhnology was obtained.
