摘      要：Annealing treatment has a strong effect on mechanical Properties of cold worked tungsten-nickel-iron heavy alloys. A 93W-4.5Ni-2.5Fe alloy swaged 15% was annealed from 500 to 1350℃ to investigate the changes in microstructure and their effects on mechanical properties. Recrystallization of W particles takes place during annealing treatments above 800℃ and the microhardnesses reduces rapidly. High density of dislocations in the, matrix phase after annealing treatment at 1350℃ suggests that recrystallization of the matrix phase has not taken place. A small decrease in microhardness of the matrix phase is caused by recovery during the annealing *** changes in mechanical properties of swaged and annealed 93W-4.5 *** alloy are mainly due to the changes in microstructure of W particles because of their recrystallization.
