对高铍铸造铍铝合金的显微组织以及拉伸试验断裂过程进行了分析，并结合GB/T 228.1-2010以及ASTM E8-2004的要求与定义探讨了用于准确评价高铍铸造铍铝合金延伸率的指标。
高铍铸造铍铝合金延伸率的评价指标Evaluation Indexes for Elongation of High Beryllium Casting Be-Al Alloy对高铍铸造铍铝合金的显微组织以及拉伸试验断裂过程进行了分析，并结合GB/T 228.1-2010以及ASTM E8-2004的要求与定义探讨了用于准确评价高铍铸造铍铝合金延伸率的指标。结果表明：由于高铍铸造铍铝合金实际上是一种以铝为基体的复合材料,拉伸试验后试样不一定完全断开,所以对其延伸率指标进行评价时，不宜采用试样断后对接的方法；最好用引伸计采集精准应变，选取合适的断裂点判据，以便测得有效的延伸率指标。
The microstructure and the tensile fracture process of a high beryllium casting Be-Al alloy were analyzed. And combining the requirement and definition of GB/T 228.1-2010 and ASTM E8-2004, the accurate evaluation indexes for elongation of high beryllium casting Be-Al alloy were researched. The results show that high beryllium casting Be-Al alloy was a kind of composite material with aluminum as the matrix, and after tensile test the samples might not be completely broken, so it was not suitable to evaluate the elongation index of it by the method of docking the fractured samples. It was better to collect accurate strain by extensometer and chose the right breaking point in order to obtain the effective elongation index.
