新西兰奥克兰大学研究人员研究发现了一种新型镁合金系,这种新型合金比目前所用的铸造和挤压镁合金具有高延性和良好的冷成形能力。该合金系主要合金元素为Sn和Pb,价格便宜,其他合金元素也不贵和/或用量较少。因此该合金系成本较低,可用于工业化批产。通过添加少量Sn、Pb和Zr,使得合金系具有较高的室温延性,最高延伸率为20%～23%,极限抗拉强度达到258MPa。力 Researchers at the University of Auckland in New Zealand have discovered a new type of magnesium alloy that has high ductility and good cold formability over the cast and extruded magnesium alloys currently in use. The alloy is based on the major alloying elements Sn and Pb, are inexpensive, other alloying elements are inexpensive and / or less used. Therefore, the lower the cost of the alloy, can be used for industrial batch production. By adding a small amount of Sn, Pb and Zr, the alloy system has higher room temperature ductility, the maximum elongation is 20% ~ 23% and the ultimate tensile strength reaches 258MPa. force
