摘要
采用恒变形速率凸轮式压缩试验机,对不锈钢、轴承钢、弹簧钢等12种钢的变形抗力做了实验研究。其变形温度、变形速率及变形程度分别为850～1150℃、5～80 s^(-1)及5～69 ％。分析了这三个变形工艺参数对变形抗力的影响。在对比两种曲线拟合方法的基础上,提出了拟合精度较高的变形抗力数学模型。本文还提供了12个钢种的塑性变形抗力的计算图表。
The deformation resistances of twelve steel grades including stainless, bearing, spring ste-els etc. have been studied using a cam-type compression testing machine with a constant strainrate. The temperature, strain rate and deformation extent of the tests ranged between 850～1150℃, 5～80 s^(-1) and 5～69% respectively. The effects of these factors on the resistance were ana-lyzed. The calculation diagrams of resistance to deformation for the twelve steel grades aregiven in this paper. Based on the comparation of fitting methods of two kinds of curve, a ma-thematical model with better fitting for resistance to deformation is presented as well.
