Notes:
The effect of the amount of dispersoids on softening behavior and recrystallizedmicrostructure of Cu-Fe-P alloy was examined by the extracted residue analysis method. Thedegrees of contribution of larger particles (larger than 1μm in an average diameter) and smallerones (less than 0.1μm) to the softening behavior were considered in the quantitative aspect,respectively. It was found that the change of the order of 10-1mass% in the amounts of bothparticles has a great effect on softening behavior. The difference in the amount of fine particleschanges recrystallized grain size distributions at similar hardness. In the specimen with a smallamount of fine particles, coarse grains and wide distribution of grain size were observed afterannealing. As a result, it was revealed that fine and homogeneous recrystallized microstructure wasobtained due to just 0.35mass% of fine partcles, even if the amount of large particles increased
