雙級時效在鑄造Mg-3Nd-0.2Zn-Zr（wt.%）鎂合金中的應(yīng)用（英文）
發(fā)布時間：2021-02-10 16:52
研究了常規(guī)雙級時效處理工藝（先低溫160℃,后高溫200℃）和反雙級時效處理工藝（先高溫200℃,后低溫160℃）對低壓砂型鑄造Mg-3Nd-0.2Zn-Zr（NZ30K）（wt.%）鎂合金的硬度和室溫拉伸性能的影響。結(jié)果表明,常規(guī)雙級時效處理對提高NZ30K合金的屈服強度效果不明顯,而反雙級時效處理能明顯提高NZ30K合金的屈服強度。經(jīng)200℃×16h+160℃×64h反雙級時效處理后,NZ30K合金獲得最佳綜合力學(xué)性能,硬度和屈服強度分別為75.7HV和161MPa。
