- Abstract
The present work has been conducted to investigate and compare the mass transport mechanism of Ni-powder particles in conventional and microwave sintering process. The linear shrinkage method was used to investigate the mass transport mechanism on the basis of estimated sintering exponent (n) at different temperatures. Both types of sintering were carried out at various temperatures, and the results revealed that microwave sintering provides better results of densification and shrinkage as compared to conventional sintering. Field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray spectroscopy (EDX) analysis were carried out for the characterization of Ni-powder for microstructural and elemental analysis. The value of sintering exponent found through linear shrinkage method for conventional was 9.4791, 8.1836, 6.9013, 7.3286, 5.2006 and 4.9531 at 500 °C–1000 °C, respectively, and microwave sintering was 7.0972, 5.2957,5.2942 and 6.0934 at 500 °C—800 °C, respectively.
