摘要
本文利用Gleeble－1500D热模拟试验机对宝钢195钢所制的Ф10min×12mm圆柱形试样的塑性变形抗力进行压缩试验研究。实测了变形温度在750—1000℃、变形速率为1／s和25／s、变形量在0．7以下时，宝钢195钢的变形抗力，建立了志田茂变形抗力数学模型并对模型进行了乘法修正。结果表明，乘法修正使模型的预报精度得到了极大的提高。
In this paper,a compression test was carried out at temperature 750 - 1000℃, in strain rate 1/s and 25/s and the strain less than 0.7, by using Gleeble 1500D with the specimen φ10mm × 12mm of Baosteel 195. Then the Shita resistance model of deformation has established based on the stress-strain datum obtained in above test. Further more the Shita resistance model of deformation has been modified by multiplication method, and the modified model accuracy is improved.
