【摘要】：以汽車用A354鑄造鋁合金為對(duì)象,通過(guò)微觀組織觀察、硬度測(cè)試等方法研究了固溶處理與時(shí)效處理中的溫度與時(shí)間對(duì)鋁合金微觀組織與力學(xué)性能的影響。結(jié)果表明,鑄造鋁合金A354最佳熱處理工藝為:固溶處理525℃×10 h,時(shí)效處理175℃×6 h。在此工藝下,A354合金的布氏硬度值達(dá)到129 HB。
[Abstract]:The effects of temperature and time on the microstructure and mechanical properties of A354 cast aluminum alloy for automobile were studied by means of microstructure observation and hardness test. The results show that the optimum heat treatment process of cast aluminum alloy A354 is as follows: solid solution treatment 325 鈩，
