Abstract
Microstructure and microhardness of precipitation/dispersion hardened Cu-Ti-B and Cu-Ti-Si alloys have been studied. Two different prealloy preparation procedures were used to obtain ingots as a starting materi al for a subsequent gas atomization process performed at 1400-degrees- C. The strengthening effect in Cu-Ti-B heat-treated powders is higher than that of heat-treated Cu-Ti alloys (with higher Ti content) produc ed by standard melting and casting procedure. The strengthening of Cu- Ti-Si powders is less pronounced.
