Effect of Annealing on Mechanical Properties of Copper Alloys Deformed at Cryogenic Temperature
The effect of annealing treatment on the mechanical properties and microstructure of cold-rolled Cu- 20% Zn alloys was investigated in this work.Mechanical properties changed dramatically with the increase of temperature.According to the microhardness test,it can roughly concluded that 150 ℃ is the optimal annealing temperature for deformation,at which a uniform elongation increased from 1.4658% before annealing to about 6.89%,and the elongation to failure increased from 7.426% to 16.81% with the same strength almost retained.The changes of microstructure during the annealing process are mainly distributed to the improvement of mechanical properties.
