Sintering was carried out in a tubular microwave furnace HAMiLab-V3 under N2 atmosphere. The holding time was selected between 0 to 75 minutes with increment of 15 minutes respectively. A study of microstructure and physical properties was carried out on sintered samples. It was discovered that, when the samples sintered at 1400oC with 20oC/min heating rate, the hardness was significantly increased from 110Hv to 160 Hv for holding time ranging from 30 to 45oC/min. Further increment until 75 minutes of holding time, no significant changes were obtained and hardness values were at steady state. The enhancement of bulk density and reduction of porosity were observed commences at 30 minutes until 45 minutes holding time. However, the results showed that the optimum holding time was at 45 minutes where the micro hardness is at the highest point which is about 160Hv. 2019-12-03T09:37:18Z 2019-12-03T09:37:18Z 2016-01 Article Key Engineering Materials, vol.673, 2016, 107-115. 1662-9795 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/63582 https://www.scientific.net/KEM.673.107 en Trans Tech Publications Ltd. |
