摘　　要：TTT图是制定钢的热处理工艺的重要依据。本软件对所测相变数据进行分段抛物处理，实现了曲线的拟合，用BASIC语言设计出具有在半对数坐标系下绘制TTT图的软件，该软件再与AUTOCAD联接，在CAD绘图软件支持下，可自动绘出精确、实用、美观的TTT图。The isothermal transformation diagram (TTT)is an important basis to make a heat treatment process of steels. In this paper, the data measured are processed by the method of section parahola insertion. The curve fitting is realized. The programme of drawing TTT diagram that is on the coordinate of half logarithms has been designed by using BASIC language. Then the programme is connected with AUTOCAD,under supporting of CAD software,the accurate practical beautiful TTT diagram is drawed automatically.
