Si含量对Al-Si-Cu-Ni-Mg合金组织和性能的影响OACSTPCD
Effect of Si Content on the Organization and Properties of Al-Si-Cu-Ni-Mg Alloys
采用搅拌铸造工艺制备不同Si含量合金,旨在揭示Si含量对Al-Si-Cu-Ni-Mg合金微观组织、力学性能和耐磨性的影响.结果表明,随着Si含量升高,合金中共晶Si长径比和平均长度先升高后降低,Si含量为16wt.％合金的长径比和平均长度最大,分别为8.8μm、24.1 μm.经过520℃/6h固溶+180 ℃/5 h时效处理后,共晶Si形貌由纤维状变为球状,初晶Si棱角钝化.合金中共晶Si长径比和平均长度均有明显降低,保持与铸态合金相同的变化趋…查看全部>>
Different Si content alloys were prepared by stir casting process,aiming to reveal the effect of Si content on microstructure,mechanical properties and wear resistance of Al-Si-Cu-Ni-Mg.The results showed that with the increase of Si content,the aspect ratio and average length of eutectic Si firstly increase and then decrease,and the aspect ratio and average length of the alloy with Si content of 16 wt.％were the largest,which were 8.8 and 24.1 μm,respectivel…查看全部>>
