In situ formation behaviors of Al8Mn5 particles in Mg–Al alloys

Al8Mn5 particles were in situ formed in an Mg–Al alloy with Mn addition. The effects of Mn content and melting temperature on the in situ formation behaviors of Al8Mn5 aluminide were investigated. It was found that increasing Mn content or melting temperature promoted the formation of Al8Mn5, and also the segregation tendency of these in situ formed aluminide particles.
