【摘要】：為了改善體育器材用鎂基合金型材的塑韌性和強(qiáng)度,基于織構(gòu)和力學(xué)性能的分析結(jié)果,采用不同的擠壓溫度、擠壓速度和擠壓比對(duì)Mg-Al-Sn-In新型鎂合金型材擠壓工藝進(jìn)行了優(yōu)化。結(jié)果表明,在試驗(yàn)條件下,隨擠壓溫度從300℃提高到400℃,型材的抗拉強(qiáng)度和屈服強(qiáng)度均先提高后下降,斷后伸長率先提高后基本不變;隨擠壓速度從1m/min增大到3 m/min或擠壓比從10增大到20,型材的抗拉強(qiáng)度、屈服強(qiáng)度和斷后伸長率均先提高后下降。與300℃擠壓相比,375℃擠壓型材的抗拉強(qiáng)度、屈服強(qiáng)度和斷后伸長率分別增加27%、62%、201%;(0002)基面的織構(gòu)最大值減小27%。型材的擠壓工藝優(yōu)選為:擠壓溫度375℃,擠壓速度2.5 m/min,擠壓比13。
[Abstract]:In order to improve the ductility and strength of magnesium based alloy profiles for sports equipment, different extrusion temperatures were adopted based on the analysis results of texture and mechanical properties. The extrusion speed and extrusion ratio of Mg-Al-Sn-In magnesium alloy profile were optimized. The results show that with the increase of extrusion temperature from 300 鈩，
