The compacted powders sintered at temperature 1200°C for 1h. Decomposition of hydroxyapatite into α-TCP (α tricalcium phosphate) and TTCP (tetracalcium phosphate) were not occured in any different nickel content before and after sintering. The Ni peaks sharply increased with increasing of Ni content indicate that high crystallinity of metal and confirmed the existence of nickel in the composites. Compared with that of pure HA, the fracture strength of HA inproved by almost 200% by adding 1wt% Ni due to the increase of the composites density. The enhancement in mechanical properties of HA-Ni composites was found to decrease with increase of Ni content, which attributed to the size effect of nickel grains and higher porosity percentage of composites. 2014-05-15T07:18:00Z 2014-05-15T07:18:00Z 2014 Article Key Engineering Materials, vol.594-595, 2014, pages 311-315 1662-9795 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34427 http://www.scientific.net/KEM.594-595.311 10.4028/www.scientific.net/KEM.594-595.311 en Trans Tech Publications
