對高鈹鑄造鈹鋁合金的顯微組織以及拉伸試驗斷裂過程進行了分析，并結合GB/T 228.1-2010以及ASTM E8-2004的要求與定義探討了用于準確評價高鈹鑄造鈹鋁合金延伸率的指標。
高鈹鑄造鈹鋁合金延伸率的評價指標Evaluation Indexes for Elongation of High Beryllium Casting Be-Al Alloy對高鈹鑄造鈹鋁合金的顯微組織以及拉伸試驗斷裂過程進行了分析，并結合GB/T 228.1-2010以及ASTM E8-2004的要求與定義探討了用于準確評價高鈹鑄造鈹鋁合金延伸率的指標。結果表明：由于高鈹鑄造鈹鋁合金實際上是一種以鋁為基體的復合材料,拉伸試驗后試樣不一定完全斷開,所以對其延伸率指標進行評價時，不宜采用試樣斷后對接的方法；最好用引伸計采集精準應變，選取合適的斷裂點判據，以便測得有效的延伸率指標。
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.
