为了满足未来航空工业的需要,研制新镁合金工作的进展是缓慢而有限的.早期所作的粉末冶金镁合金的研究成效不大.在50年代,Busk和Leontis用惰性气体雾化金属熔体来生产各种镁合金粉末之后,旋转圆盘雾化工艺也应用于生产镁粉.不过,在这些早期的雾化工艺冷却速度不能达到很高.后来在应用雾化工艺生产快速凝固镁粉方面的工作是,Isserow和Rizzitano用旋转电极法制造工业合金ZK60A(Mg-6%Zn-0.45%Zr)粉末.不过,用旋转电极法制得的粉末,平均粉粒尺寸大约为100微米,这种粉粒的冷却速度<10~4K/
In order to meet the needs of the aviation industry in the future, the progress made in the development of new magnesium alloy is slow and limited.Prior studies of the powder metallurgy magnesium alloy have been less successful.In the 1950s, Busk and Leontis atomized the metal melt with inert gas After the production of various magnesium alloy powders, the rotary disk atomization process was also applied to the production of magnesium powder, however, the cooling rate in these early atomization processes did not reach very high, and later in the application of atomization process to produce rapidly solidified magnesium powder The work was that Isserow and Rizzitano manufactured the industrial alloy ZK60A (Mg-6% Zn-0.45% Zr) powder by the rotating electrode method. However, the powder produced by the rotary electrode method had an average particle size of about 100 micrometers, Cooling rate <10 ~ 4K /
