| Summary: | 97%Sn 2%Cu 1%Sb (pewter) alloys were examined to determine the effect of green density,
sintering time and sintering temperature on the mechanical and structural properties of the
conventional and microwave sintered compacts. Two compaction loads; 30kN and 40kN were
used to produce the samples with different green densities. Eight different time-temperature
combinations were used for each heat treatment. Samples with a higher green density resulted in
a higher sintered density and higher hardness. Longer sintering time and higher sintering
temperatures resulted in higher densities, larger grain size and higher hardness for both sintering
methods. However, the microwave sintered samples in general have finer microstructures, higher
densities and higher hardness compared to the conventional sintered samples in a much shorter
duration. Better mechanical and structural properties were achieved by microwave sintering in
15 minutes compared to conventional sintering which took 120 minutes. |
