Developing a high-speed-extruded BMZQ5100 alloy with higher strength and microstructural thermal stability than AZ91 alloy J. Alloys Compd. (IF 6.2) Pub Date : 2024-03-18 Li Wang, Shouxin Xia, Haowei Zhai, Xu Qin, Jiaze Xu, Jun Xu, Bin Jiang, Weiying Huang, Chaoqiang Sun, Yuhui Zhang, Qinghang Wang
A new Mg-5Bi-1Mn-0.5Zn-0.2Ag (BMZQ5100, wt%) alloy is developed and analyzed comparatively its extrudability, microstructure, mechanical property and thermal stability with a commercial AZ91 alloy. The results show that the BMZQ5100 alloy can be successfully extruded at a high extrusion speed (ES) of 30 m/min without surface cracks, but there are a large number of hot cracks occurred on the low-speed-extruded
