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

    Graphical Abstract
    • 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.
