ABSTRACT
The HSn88-2 alloy was subjected to cold deformation with different degrees ,and the working hardening curve of the alloy was drawn .Through the microstructure observation and test of the tensile strength and elongation of specimens with different thicknesses after annealing, the recrystallization temperature of the alloy was obtained .The results show that the alloy after cold deformation has obvious working hardening effect .The strength of the alloy increases first and then keeps constant with the increasing of working rate ,while the elongation and electrical conductivity exhibit opposite change rule .In addition ,the lower the cold working rate is ,the lesser the initial recrystallization temperature is.
