In order to study the mechanism of age-hardening in Al-Cu-Sn alloy, a study was made on alloys containing 2 to 5 percent copper and 0 to 5 persent tin quenched from 500° in water after being heated at that temperature for I/2 hour, and tempering for various hours at 100°, 150°and 175°respectively;
The variation in hardness of the alloys due to the above heat treatment has been studied by means of hardness tester. When a small amount of tin is added to the alloys, the artificial age-hardening property was vigorously accelerated compared with Al-Cu alloy for instance, the degree of hardening of some alloys reached to two hundred percent.
