本文提出一种测定烧结材料拉伸强度用的圆片状试样,用于烧结硬铝合金的强度检验,其实验结果的重现性获得满意的结果,与标准拉伸试样的偏差为3%左右。圆片状试样容易制作,可用于工艺参数的筛选和生产过程的质量控制。
In this paper, a kind of disk-shaped sample for measuring the tensile strength of sintered materials is proposed for the strength testing of hard-aluminum alloy. The reproducibility of the experimental results is satisfactory. The deviation from the standard tensile sample is 3 %about. Wafer-like samples are easy to make and can be used for the screening of process parameters and the quality control of production processes.
