This 132-page book represents a complete study of the?consstitUtiO chic
grains of the A1-M6-Zu alloy by P-?{,hods of theiw . and -?? alto
analysis. A great deal of attention has been paid to determining the
polythermal range for crystallization of the aluminum-base solidhsolu
tion in connection with the nature of intermetallic phases,
necessary for the characterization of commercial alloys.
