摘要
采用光学显微镜和拉力试验机,研究了复合细化变质对再生ADC10铝合金显微组织与力学性能的影响。结果表明:通过复合细化变质使再生ADC10铝合金的α-Al晶粒从粗大的树枝状转变为细小均匀的等轴状,使共晶Si相和富Fe相从粗大的针片状转变为细小的纤维状和颗粒状,可显著提高再生ADC10铝合金的力学性能。与未细化变质相比,细化变质后再生ADC10铝合金的抗拉强度为289.2MPa,断后伸长率为7.8%,抗拉强度提高了16.7%,断后伸长率提高了52.9%。
The effects of refining and modification on the microstructure and mechanical properties of recycled ADC10 aluminum alloy were studied by means of optical microscope and tensile testing machine.The results show that the mechanical properties of the recycled ADC10 aluminum alloy can be improved significantly by adding grain refiner and modifier.The tensile strength of the recycled ADC10 aluminum alloy with refining and modification is 289.2 MPa,and the elongation after fracture is 7.8%.The tensile strength is increased by 16.7%and the elongation is increased by 52.9%compared with that of the recycled ADC10 aluminum alloy without refining and modification.
