摘要
A review of crystallochemical thermodynamic and phase diagram data of Mg RE and Al RE based systems is presented. On the basis also of their possible applications, special attention is given to the Mg rich and Al rich alloys and to the effects of rare earth additions on their properties. A summary of the experimental work carried out by our research group on several binary and ternary alloys is reported: that is Mg RE, Al RE, and Mg RE RE′ and Al RE RE′ with two different rare earth metals. A number of regularities observed in the formation and in the crystallochemistry of binary and ternary Mg rich or Al rich phases are summarised and discussed. Their application to a fine planning of alloys having a well defined structure is suggested.
