Abstract: (6237 Views)
Combustion synthesis has been used to produce Fe-(Ti,W)C composites. A simple reactor was designed which made it possible to ignite the samples under controlled atmosphere. Samples with different W/Ti ratio were ingnited under argon atmosphere by an electric arc and a self-propagating reaction was initiated in each sample. Different composites such as WC in Fe-Ti matrix, WC+(Ti,W)C in Fe matrix, and (Ti, W)C in iron matrix were produced by changing W/Ti ratio in the starting materials. Examination of the microstructure revealed that WC had an angular morphology while (Ti, W)C particles were spherical.
