摘要
耐热铝合金具有良好的中温性能,在兵器、航空、航天以及汽车工业中应用广泛。综述国内外耐热铝合金材料的研究进展,重点介绍合金元素对铝合金耐热性的影响;从固溶强化、弥散强化、过剩相强化和晶界强化几个方面介绍了耐热铝合金的强化机理;并展望耐热铝合金的发展趋势。
Heat-resistant aluminum alloys had been used widely in ordnance,aerospace and automotive industry for the excellent intermediate temperature properties.The research developments of heat-resistant aluminum alloys were reviewed in this paper,the influence of various alloy elements on the heat resistance of aluminum alloy was introduced in detail.The solution strengthening,dispersion strengthening,surplus strengthening and grain boundary strengthening of aluminum alloys were summarized,and the future development trend of heat-resistant aluminum alloys was discussed.
