A comparative study on mechanical properties of heat treated steel EN24 and its MMC with SiC

摘要

The investigation has been undertaken to evaluate the mechanical properties of sintered and heat treated EN24 alloy steels by using elemental powders through powder metallurgical techniques. The green compacts obtained through powder metallurgy route have been sintered at 1150±10°C in vacuum furnace. Silicon carbide content used as reinforcement in EN24 matrix is varied and tensile specimens are prepared. Tensile test specimens prepared from EN24 steel plate is subjected to standard heat treatment. Both Sintered and heat treated EN24 steels are subjected to tensile tests with by 40 Tonn Capacity Hydraulic Universal Testing Machine. Their microstructures are evaluated using optical and electron microscopy. From the data obtained a comparison of the properties of the En 24 composite with heat treated En 24 steel has been attempted.
