应用Ｆｏｒｍａｓｔｏｒ－Ｄｉｇｉｔａｌ全自动相变仪测定了Ｈ１３钢的退火用ＴＴＴ图。利用物理化学相分析法研究了Ｈ１３钢在Ａ１稍下的转变产物，分析了球化组织中基体的成分和碳化物的结构及相对量。
Formastor-Digital automatic phase change instrument was used to measure the TTT of H13 steel. The phase transformation products of H13 steel under A1 were studied by means of physical-chemical phase analysis. The composition of matrix and the structure and relative amount of carbides in spheroidized structure were analyzed.
