Abstract
The aim of the present project is to investigate the friction stir weldability of novel light and recyclable high-performance materials based on the ZK60 magnesium alloy (Mg-6%Zn-1%Zr) modified with different mischmetal (RE) contents: 0.5, 1.5 e 2.5 wt%. For the production of such materials still unexplored in Brazil, it is proposed the use of a thixocasting procedure under mechanical sti…
