摘要: 为了研究炸药参数对高锰钢爆炸硬化效果的影响，对两种不同密度的炸药进行爆速测试，并利用该炸药分别对高锰钢试样进行爆炸硬化实验，测试了从硬化表面向材料内部的硬度、抗拉强度和冲击韧性随深度的变化。测试结果表明：高锰钢试样在相同深度下，经过密度1.38 g/cm³炸药3次爆炸硬化得到的硬度大于密度1.48 g/cm³炸药2次爆炸硬化后的硬度，而冲击韧性小于密度1.48 g/cm³炸药作用后的冲击韧性；从爆炸硬化表面向下15 mm内，经过密度1.38 g/cm³炸药3次爆炸硬化得到的抗拉强度大于密度1.48 g/cm³炸药2次爆炸硬化后的抗拉强度，但深度大于15 mm时，经过密度1.38 g/cm³炸药3次爆炸硬化得到的抗拉强度小于密度1.48 g/cm³炸药2次爆炸硬化后的抗拉强度。从硬化后试件的硬度、抗拉强度以及冲击韧性这3方面考虑，使用单次爆炸冲量较小的炸药进行多次爆炸硬化效果较好。

Abstract: In order to study the influence of explosive parameter on the effect of explosion hardening of the Hadifield steel, detonation velocities of two different densities of explosive were tested respectively. The variation of internal hardness, tensile strength and impact toughness from the hardened surface to inside the material with depth was tested respectively. The hardness and impact toughness of the sample for triple explosion with the density of 1.38 g/cm³ are larger than those for twice explosion with the density of 1.48 g/cm³ at the same hardening depth. The tensile strength for triple explosion with the density of 1.38 g/cm³ is higher from the surface to 15 mm below the hardened surface but is lower from 15 mm down. For the hardness, tensile strength and impact hardened toughness consideration, the effect of explosion hardening for the smaller single impulse is better.
