Experimental investigation on aging treatment of 7050 alloy assisted by electric pulse

The microstructural evolution in 7050 alloy during rapid aging treatment was studied by using electrical pulse technique, and the properties of 7050 alloy has been investigated. Compared with the alloy experiencing the conventional heat treatment (CHT), the strength and hardness of the 7050 alloy is...
