The secondary explosive welding process promotes the diffusion of the carbon element and accumulation of chromium carbide, which leads to a decrease of tensile properties and toughness of the material. In this work, the average shear strength value increased from 400 to 421 MPa. The crack of the fatigue specimens started from the inclusions rich in alumina near the surface, and the harmful hard-phase inclusions were exposed because of stress concentration. The maximum load limit of 10CrNi3MoV steel undergoing secondary explosive welding was between 590 and 605 MPa.

二次爆炸焊接对10CrNi3MoV钢基复合板组织和力学性能的影响

二次爆炸焊接过程促进了碳元素的扩散和碳化铬的积累，从而导致材料的拉伸性能和韧性降低。在这项工作中，平均抗剪强度值从400 MPa增加到421 MPa。疲劳试样的裂纹始于表面附近富含氧化铝的夹杂物，并且由于应力集中而暴露出有害的硬相夹杂物。二次爆炸焊接的10CrNi3MoV钢的最大载荷极限在590 MPa至605 MPa之间。
