Effect of Rolling Deformation on Microstructure,Mechanical Properties and Corrosion Resistance of Zn-3Cu Alloy
The effects of rolling deformation on the microstructure,mechanical properties and corrosion resistance of Zn-3Cu alloy were studied.Results show that with the increase in rolling deformation,the grains of Zn-3Cu alloy matrix are refined,and the CuZn4 phase in the alloy is elongated and partially broken along the rolling direction.The strength of Zn-3Cu alloy increases first and then decreases,and the plasticity increases continuously.The Zn-3Cu alloy with the deformation of 60％has the highest yield strength,reaching(263.1±4.9)MPa.With the increase in deformation,the corrosion resistance of the as-rolled Zn-3Cu alloy gradually decreases,while the as-cast Zn-3Cu alloy exhibits excellent corrosion resistance.
