Structural and mechanical behavior of Al2O3-reinforced Fe metal matrix composites (MMCs) produced by powder metallurgy (P/M)

The present paper reports the effect of sintering parameters (i.e. temperature and time) on the properties of Fe–Al2O3 composite) prepared by powder metallurgy process. X-ray diffraction, microstructure, density, hardness and compressive strength of prepared samples have been investigated. XRD studies show the presence of iron and alumina along with iron aluminate phase. SEM studies also showed showed a dense structure of the reinforcement of ceramic phase. Results have been discussed to illustrate the effect of various processing parameters on Density as well as hardness of specimens.
