摘要

在Thermecmastor-Z热模拟试验机上对0.045%Ti-0.003%C的Ti-IF钢进行700～950℃、应变0～0.7、应变速率1～70s

条件下的热模拟实验

以分析温度、应变速率和应变量对变形抗力的影响。用BP(back propagation)网络神经算法给出了Ti-IF钢在800～875℃变形抗力预报模型。通过对模型预报值和实验数据实测值的比较得出

变形抗力相对误差在4.0%以内。

Abstract

Thermal simulation test for 0. 045Ti-0. 003 C Ti-IF steel with strain 0 ~ 0. 7 and strain rate 1 ~ 70 s

-1

at 700 ~950℃ has been carried out by thermecmastor-Z simulation mat'hine to analyze the effect of temperature

strain and strain rate on deformation resistance. The prediction model of tieformation resistance of the Ti-IF steel at 800 - 875℃ was obtained by BP neural net calculation method. With comparison between model predicted value and actual measured value

it indicated that the relative error of deformation resistance was less than 4. 0% 。
