| dc.description.abstract |
Impression creep behaviour of the powder metallurgy processed steel matrix composites was investigated under constant stress at different temperatures in the range of 873-973 K. By using the power-law relationship, the estimated activation energy for unreinforced steel was found to be 149 kJ mol(-1) and steel reinforced with 2 and 4 vol.-% TiB2 was found to be 298 and 338 kJ mol(-1), respectively indicating better creep resistance of the reinforced steel matrix composites. Dislocation creep is the dominant creep mechanism based on the calculated values of stress exponent and activation energy. Hence, this method can be used to assess the potential of steel matrix composites for use as structural materials for high-temperature application. |
