- Abstract
The present work aims to study the effect of thermo–mechanical processing on the microstructure, impact abrasion wear, and corrosion resistance properties of a Fe-17Mn-3Al (wt.%) steel matrix composite reinforced with 10 wt.% TiC, synthesized by the conventional melting and casting route. The high-manganese steel matrix composite (HMSMC) was homogenized at 1100°C for 1 h followed by forging with a 50% reduction in thickness. Then, the steel was subjected to warm rolling at 1100°C to achieve a 30% reduction in thickness followed by annealing at 800°C. In this work, the applied thermo–mechanical processing of the investigated HMSMC consists of forging, warm rolling, and annealing at 800°C. The XRD patterns of the homogenized and thermo–mechanically processed HMSMC show the presence of α-ferrite, γ-austenite, and TiC phases. In addition, the SEM micrographs corroborate the presence of ferrite in the inter-dendritic region, austenite in the dendritic region, large TiC particles in the inter-dendritic region, and small TiC particles in the dendritic region. Thermo–mechanical processing improves the density, hardness, impact abrasion wear (IAW) resistance, and corrosion resistance of the HMSMC. The improvement in properties is due to the thermo–mechanical processing which closes the pores and microvoids.
