| dc.description.abstract | This study is to examine the effect of sintering parameters on the densification
and mechanical properties of microwave sintered 316L stainless steel powder. The
sintering parameters investigated were: sintering temperature, heating rate and sintering
time. Sintering atmosphere was fixed to nitrogen gas. 316L stainless steel compacts
were heated in a 2.45 GHz single mode microwave sintering furnace. In order to achieve
the optimal densification, hardness, and compressive stress, the effects of various
sintering factors pertaining to the temperature, time profile and heating rate have been
characterized. In this paper reports 2-level factorial of three sintering factors have been
used to set up the experiment. It was found that all the sintering factors have the
sintering effects on the final result. Various factors were assigned to DOE layout and
were found that all the chosen sintering factors have significant effects on the
densification and mechanical properties. The optimization of the design which selected
is 1300°C , 30°C and 54.19 min. The estimate density, hardness, and compressive
strength value are 7.06g/cm3, 54.87 HRA and 332.78 MPa respectively. | en_US |
