Improved properties of AZ81 magnesium alloy produced by MIM

摘要

In the June 2018 issue of Powder Injection Moulding International(Vol.12,No.2,pp.41-42)we reported on work at the Helmholtz-Zentrum Geesthacht,Germany,on the potential use of Metal Injection MouLding to produce complex-shaped magnesium alloy components for technical applications.One alloy was based on gas atomised Mg-2.6Nd-1.3Gd-0.5Zr-0.3Zn powder designated EZK4-00 and this was processed by pressing and sintering.The second was a Mg-8Al-1 Zn alloy referred to as AZ81 which was processed by MIM.The initial results of mechanical testing were given for both alloys.However,the authors concluded that in order to implement the use of the MIM process to produce Mg alloy AZ81 alloy components,an improvement in strength values was reguired.
