对13种常用铝合金进行了拉伸试验和布氏硬度试验。在拉伸试验时测出了硬化指数n 和均匀延伸。关于布氏硬度的测定日本广泛应用的是加载球直径10毫米,试验载荷500公斤的试验方法。本文将进一步研究使用多大的载荷才能得到最佳的结果。
Thirteen commonly used aluminum alloy tensile test and Brinell hardness test. Hardening index n and uniform elongation were measured during the tensile test. About the determination of Brinell hardness Widely used in Japan is to load the ball diameter of 10 mm, the test load of 500 kg test method. This article will further investigate how much load is used to get the best results.
