eutectic Al/Cu powder was used to prepare Al/Cu alloys by SHS-sintering(laser-induced self-propagating high-temperature synthesis).Influences of the pressing pressure
laser power and sintering time on microstructure of the sintering alloys
densification and hardness were studied by SEM
OM
XRD and Brinell′s Hardness Tester.It was found that uniformity and relative density of the sintering alloy increased with the laser power and sintering time.When the relative density of the original compacts was 85%
the sintered density could be up to 3.11 g/cm3;the highest hardness of sintered alloy was 131HB and this was at the central area.In order to estimate the sintering cooling rate of the location
the measure of secondary dendrite arm spacing is proposed.
