用计算机对低合金钢的过冷奥氏体转变动力学进行了数学模拟，综合考 虑了冷却速度、合金化学成分和晶粒度等因素对过冷奥氏体转变的影响。利 用ｄＢＡＳＥ Ⅲ程序设计语言和ＢＡＳＩＣＡ程序设计语言建立了合金钢数据库， 并在ＩＢＭ－ＰＣ机上绘出了ＴＴＴ曲线及ＣＣＴ曲线。
The kinetics of undercooled austenite transformation in low alloy steels was simulated by computer. The effects of cooling rate, alloy composition and grain size on the transformation of undercooled austenite were comprehensively considered. The alloy steel database was established by dBASE Ⅲ programming language and BASICA programming language, and TTT curve and CCT curve were drawn on IBM-PC.
