Drawing of Time Temperature Transformation (TTT) of Steel’s Metastable Austenite by Computer
-
摘要: TT图是制定钢的热处理工艺的重要依据。本文介绍了一套程序,它通过对所测数据进行三次样条插值处理,实现了曲线的拟合,再通过AutoCAD二次开发,自动绘制出精确、美观的TTT图。Abstract: TTT diagram is an important reference in making heat treatment procedure for steels. A program is introduced in this paper with which the TTT diagram of M30Mn2 steel is fitted through cubic spline treatment of the test data, and a precise and smooth TTT curve is auto drafted by programming with AutoCAD.
