Mechanical properties of sintered Fe-C alloys through Spark Plasma Sintering technique
B. S. Rao
Several observations from recent years suggests that the strength of the materials can be increased to great levels by the reduction of grain size. But the main obstacle to reduce the grain size is the lacking of a suitable technique. Recently several techniques has been invented in order to achieve this objective, in these mechanical alloying and subsequent consolidation through spark plasma sintering (SPS) technique is promising one. Through this process, the minimum grain size that can be achieved is of the order of few nanometers depending on the material.
Fe-C alloys are the most widely used structural material. Its strength can be tuned with the help various processing routes subsequently with different microstructures. In the current study several Fe-C alloys have been made through mechanical alloying and consolidated with SPS technique and their mechanical properties were evaluated.
