Abstract

Abstract To prevent failure of machine components it is necessary to measure material damage generated in a component throughout its entire lifetime. Damage can be quantified by means of damage parameters. This paper considers the usefulness of hardness measurements to evaluate damage parameter in Inconel 718. Vickers hardness tests were performed on a specimen with a variable cross section area after tensile testing. The specimen’s geometry enabled the evaluation of damage parameter in respect of hardness measurements made on one individual specimen.

Inconel 718损伤对维氏法测定硬度的影响

摘要为了防止机械部件的失效，有必要对部件在其整个使用寿命中产生的材料损伤进行测量。损伤可以通过损伤参数来量化。本文讨论了硬度测量在评估英科乃尔718损伤参数中的作用。在拉伸试验后，对具有可变截面面积的试样进行维氏硬度试验。试样的几何形状使得对单个试样进行硬度测量的损伤参数的评估成为可能。
