硬度对合金材料耐电压强度的影响

Effects of Hardness on Alloys Breakdown Field

结合材料学与电子学的有关理论和实验方法，以铬青铜（１％Ｃｒ）和４０Ｃｒ钢为例，考察了合金材料硬度对其耐电压强度的影响．实验结果表明：合金材料的耐电压强度与其硬度、成分和显微组织等多种因素有关。

The hardness and breakdown field of bronze and 40Cr steel were measured. Experimental results show that the breakdown field of alloys depends upon their microstructure, components and hardness. It isnt suitable to take hardness as the only judgement criterion of alloys breakdown field.
