The process of precipitation can be accelerated as the cold deformation before aging.
A process for fabricating CuCrZr alloy spot-welding electrode by three cold extrusions is developed, with effect of cold deformation on alloy properties explored.
If the cold deformation rate is higher than 70 %, the recrystallized grain size distribution agrees with lognormal distribution.
Due to the effect of strain hardening, higher amount of cold deformation resulted in superior room temperature strength and inferior torsion ductility.
It is indicated that the tensile strength of GH625 is increased but the ductility is decreased with increasing the degree of cold deformation.
Therefore titanium and metal alloy of titanium have fine and overall properties. However, the titanium alloy that can be made of upscale metal spectacles must have good cold deformation.
