计算机绘制钢的过冷奥氏体等温转变（TTT）曲线

Drawing of Time Temperature Transformation （TTT） of Steel’s Metastable Austenite by Computer

    摘要
  • 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.
