由于很高温度下材料的屈服强度较低，因此只需较低压力就能挤压。
By pressing at very much higher temperatures lower pressures are required as the yield strength of the material is lower.
重点研究了平压头压入过程中，不同屈服强度比（软薄膜屈服强度与硬基体屈服强度之比）以及不同压头尺寸下硬基体对压痕规律的影响。
The emphasis was put on the critical indentation depth with the influence of the yield strength ratio of the soft film to the harder substrate and the size of the indenter.
用比拟的方法分析和计算了爆炸焊接条件下，爆炸复合材料结合区中塑性变形金属的动态屈服强度值。
This paper analysed and calculated the dynamic yielding strength of plastic deformed metal in the bonding zone of explosive welding composite material in the condition of explosive welding.
