| 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线处理，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，自动绘出精确、实用、美观的ＴＴＴ图。

| Abstract: | The isothermal temperature transformation diagram(TTT) is an important basis to formulate a heat-treatment technololgy of steels. In this paper, the data measured are processed by the method of section parabola 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 program me is connected with Auto CAD, under supporting CAD software, the accurate practical beautiful TTT diagram is drawed automatically. |
