And the relations of hardening exponent and hardening rate with strain were analyzed.

分析了合金的硬化率和硬化指数与应变的关系。

The value of strain-hardening coefficient can be determined from the slope of logσ-logε curve, which is numerically equal to the maximum uniform true strain. So the strain-hardening coefficient can be used to evaluate the extend of uniform plastic deformation.

由拉伸实验得到的logσ-logε曲线的斜率即为应变硬化指数，其数值与材料拉伸变形时的最大均匀应变相等，是衡量材料塑性均匀变形能力的力学指标。

In this paper,the laser hardening technological parameters and the nigrescence technology with surface oxidation have been studied on tiny workpieces of 4Cr13 stainless steel,while the influences of the laser technology and various lapping ratios on hardness,depth and microstructures of the hardening layer have been explored.

The research results show as follows. As plastic deformation increases, the Young's modulus of material continuously changes. This variation law is able to be described using a piecewise linear function .Hardening model and whether the variation is considered or not make great effet on springback prediction. It is proved that the springback prediction result which adopts the elastic-plastic constitutive model based on INLK hardening model and the variation of Young's modulus is considered, is more close to experimental result. After the sheet metal undergoes multiple bending, the corner radius and bending height also affect springback greatly.But the effect trend is different. At the same time, the reliability of springback research using numerical simulation is proved.

研究结果表明：材料弹性模量随塑性变形的变化是不断变化的，该变化规律可用分段线性函数进行描述；强化模型及考虑弹性模量变化与否对回弹预测有很大的影响，基于INLK强化模型和考虑弹性模量变化的弹塑性本构模型对回弹的预测结果与试验最接近；多次弯曲中圆角半径与弯曲高度对板料变形后的回弹有较大影响，但影响趋势不同；证明了数值模拟方法对回弹研究的可靠性。
