通过研究不同组织钢的应变硬化指数的变化趋势，建立了快速准确测定最大应变硬化指数的方法。利用材料的屈服强度和抗拉强度，建立了最大应变硬化指数与屈服强度比之间的定量关系。对确定最大应变硬化指数的三种方法进行了评价。
The method for the rapid and accurate determination of the maximum strain–hardening exponent was developed by investigating the change trend of the strain–hardening exponent of the steels with different microstructures. The quantitative relationship between the maximum strain–hardening exponent and the yield strength ratio was also determined by using the available yield and tensile strengths of the materials. The three methods of determining the maximum strain–hardening exponent were evaluated.
