摘要
分别对厚度为1.0,1.5,2.0 mm的不锈钢-碳钢层合板进行激光弯曲试验。采用金相显微镜、电子探针和扫描电镜能谱仪对激光弯折区的元素扩散现象进行分析;采用纳米压痕试验测得过渡层附近的纳米硬度及弹性模量分布,对过渡层处纳米硬度、弹性模量和屈服强度的变化进行了分析。结果表明,弯折区过渡层处元素沿板厚方向连续稳定扩散,Fe、Ni、Cr元素扩散范围相近,1.0,1.5,2.0 mm厚层合板的过渡层厚度分别增加了2.5,3.5,3.0 μm。元素扩散促进了过渡层的冶金结合,保证了层合板过渡层的材料性能。
Abstract
Laser bending experiments are performed on stainless steel-carbon steel laminated plates with thickness of 1.0, 1.5, and 2.0 mm. The element diffusion in the transition layer of the bending zone is analyzed by means of metallographic microscope, electron microprobe and energy dispersive spectrometer, the nano-indentation tests are used to obtain the nano-hardness and elastic modulus of the transition layer, and the variation in elastic modulus, nano-hardness and yield strength is analyzed eventually. The results demonstrate that the element in the transition layer diffuses continuously and steadily along the plate thickness, the diffusion ranges for Fe, Ni, and Cr are similar, and the transition layer thickness for 1.0, 1.5, and 2.0 mm thick laminated plates increases by 2.5, 3.5, and 3.0 μm, respectively. Good material properties in transition layer is ensured by element diffusion in the bending zone, and favorable metallurgical bond in laminated plates is also improved.
