Shock loading is an effective method of bulk hardening of materials. This study of the structure and mechanical properties of 110G13L steel before and after explosion loading showed that the mechanical characteristics reached maximum values at the surface of the explosively treated material: Vickers hardness HV =480, yield strength of 850 MPa, and tensile strength of 1240 MPa. The thickness of the hardened layer was ≈40 mm. For steel without shock loading, the above parameters had the following values: HV =240, yield strength of 355 MPa, and tensile strength of 840 MPa. Metallographic studies revealed that the number of slip lines in grains decreased with distance from the explosive loading surface.

爆炸对110G13L钢力学性能的影响

冲击载荷是材料整体硬化的有效方法。对110G13L钢在爆炸加载前后的组织和力学性能的研究表明，经爆炸处理的材料表面力学特性达到最大值：维氏硬度HV=480，屈服强度为850MPa，抗拉强度为1240兆帕。硬化层的厚度为≈40 mm。对于无冲击载荷的钢，上述参数取值为：HV=240，屈服强度为355MPa，抗拉强度为840MPa。金相研究表明，晶粒中滑移线的数量随着距炸药加载表面的距离而减少。
