摘要

摘要:前人的研究表明应变硬化对Inconel 718的硬度有相当大的影响。为了验证被试材料中与损伤机制相关的材料的弱化，对拉伸后的试样进行了硬度测试，随后对试样进行了热处理。试验表明，热处理后，测量的硬度随着热处理前塑性变形程度的增加而降低。

The Impact of Damage in Anneling Inconel 718 on Hardness Measured by the Vickers Method

Abstract In the previous work [1] it was shown that strain hardening had considerable impact on the hardness of Inconel 718. In order to verify the weakening of the material associated with the damage mechanism in the tested material, the hardness tests were performed on the stretched specimen which was subsequently heat treated. The tests revealed that, after heat treatment, the measured hardness was reduced with an increasing degree of the plastic deformation present prior to heat treatment.
