一、前言钕对镁合金具有较好的强化效果而引起国内外研究者的重视,并进行了大量研究工作。我国于六十年代研制或镁-钕-锆系 ZM6铸造镁合金,并在航空工业中得到了应用。苏联在发展了镁-钕-锆三元合金后,又进一步研究了镁-钕-锌-锆系四元合金的性能,证明锌能提高镁-钕-锆系合金的高温抗蠕变性能
I. INTRODUCTION Neodymium has a good reinforcing effect on magnesium alloys and has drawn the attention of researchers both at home and abroad and carried out a great deal of research work. China developed in the sixties or magnesium - neodymium - zirconium ZM6 cast magnesium alloy, and in the aviation industry has been applied. After developing the magnesium-neodymium-zirconium ternary alloy, the Soviet Union further studied the properties of the magnesium-neodymium-zinc-zirconium tetragonal alloy and proved that zinc can improve the high temperature creep resistance of the magnesium-neodymium-zirconium alloy
