分析结果表明，断裂钢轨化学成分满足标准要求，低倍组织和显微组织正常，断口呈脆性断裂解理特征，断口处氧化严重。
The results show that the chemical composition, macrostructure and microstructure are normal, the fracture appearance is brittle crowbarand, and the fracture was oxygenated severely.
对产品的机械性能和电性能进行了测试，并对断口进行了扫描电镜的观察。结果表明，双金属的结合性能良好，各项性能指标均达到相关标准。
By the observation of SEM and the test of mechanical property, the properties of aluminum-clad steel wire produced is in accord with the standard ASTM.
