【摘要】 研究了不同加入量的Fe对高铝青铜铸态组织和性能的影响。结果表明,随着Fe含量增加,合金晶粒得到细化,硬化相K相增多,其分布由弥散粒状向球状或梅花状转变,(α+γ2)共析体由少量不连续分布变为围绕K相的孤立点状分布,适量Fe(4%)可以提高合金抗压强度和硬度,过多Fe则将导致抗压强度和硬度降低。更多还原

【Abstract】 The influence of different iron content on As-cast High Aluminum Bronze’s Microstructure and Properties have been studied. Results shown that with the increasing of Fe content, matrix grain size decreases, content of hard K-phase increases, and the sharp of K-phase changes from dispersed dot type to sphere and cinquefoil, eutectoid(α+γ2)changes from discontinuous block to isolated point which surrounds the K-phase. Depress strength and hardness of the developed alloy have been increased with proper content(4%), while mechanical properties have been deteriorated with overfull iron content.更多还原
