Relationship between car forgings Performance and Two - stage Aging Treatment

- Sep 22, 2017 -

With unique performance, forgings have been applied to various industries, the more typical and the larger amount is the automotive manufacturing industry, car forgings are set in various parts of the car, wheel wheels are made of aluminum forging, it What are the factors that affect performance?

 

After the injection of the formation of the car wheel forging also need to double-stage aging treatment, this time the performance of automotive castings will change with the aging time, such as its tensile strength and yield strength will decline, but this The rate of decline will gradually decrease.

 

Experiments show that with the extension of the secondary aging time, the car forgings increased from the yield to the fracture of the plastic deformation stage, thereby enhancing its anti-rupture performance; In addition, with the secondary aging time, car forgings along the sampling direction Plastic, toughness will continue to increase.

 

In the T74 and T73 state of the car forgings test, the results of a significant plastic extension and necking, which is the phenomenon of typical tough fracture fracture; due to the fracture toughness of automotive forgings also increased, making the wheel under overload conditions Anti-rupture performance with a tough toughness damage to meet the practical requirements of automotive wheels.

 

In addition, after two aging, the car forging conductivity than in the T6 state to improve a lot; with the secondary aging time, its conductivity will continue to increase. It seems that the two-stage aging treatment will help improve the performance of car forgings, and time is one of the main factors affecting its performance, so to the appropriate control.
