对五种含碳量不同的钢材,工业纯铝及无氧铜作了高温硬度测量和不同应变率的高温拉伸试验。对于每一种新研究的材料,在广阔的温度范围内,其显微维氏硬度值与高温拉伸特性是有关的这一事实,确定了试验条件。1 概述由于高温硬度测定非常简单,而且可以一个试样上获得众多数据,因此,目前高温硬度测定已被广泛地应用于金属的研究中。特别是对于脆性材料,当不能使用其他试验方法或在实践中很难对其
Five kinds of steel with different carbon contents, industrial pure aluminum and oxygen-free copper were tested for high temperature hardness and high temperature tensile tests with different strain rates. For each newly studied material, the fact that its micro Vickers hardness is related to high temperature tensile properties over a wide temperature range, the test conditions were established. 1 Overview Due to the very simple determination of high temperature hardness and the availability of a large number of data on a single sample, the determination of high temperature hardness has been used extensively in the study of metals. Especially for brittle materials, when other test methods can not be used or are difficult to practice in practice
