| 摘 要： | 采用多种试验方法研究了Ｃｕ对高硅铸铁的组织与性能的影响。结果表明，在ＳＴＳｉ１５高硅铸铁中添加７％Ｃｕ，可使石墨呈细小花瓣状，并在晶界上有富Ｃｕ新相析出，从而可降低高硅铸铁的硬度，提高其塑性，对耐蚀性能也有明显改善。

| Abstract: | Several kinds of test methods are applied to investigate the microstructure and properties of containingCu high silicon cast iron. Experimental results show that STSi15 high silicon cast iron containing 7%Cu can allows thegraphite become small petal shape , and there is new precipitated phase of rich copper in intercrystalline.Thus lowerhardness and higher plasticity of high-silicon cast iron can be obtained ,and the corrosion resistance can be obviously im-proved.[ |
