Abstract [en]

Machines contain parts which work under severe wear conditions and suffer from significant wear damage. In this thesis, the specific part of milling machines contacting with amount of milled rocks for a long period of time, has been studied. The severe wear damage can lead to undesirable failure and cause uncountable economic losses. The project was therefore aimed to develop an advanced metal matrix composite material (MMCs) to increase the hardness and improve the wear resistance of manganese steels. The entire project was mainly divided into three parts: theoretical study in order to increase the understanding of the synthesis in MMC manufacturing; experimental study of the synthesis of TiC reinforced manganese steels; material characterization of the MMCs produced in order to investigate the effect of different experimental parameters on the formation of TiC. For this project, TiC has worked as a reinforcement phase to improve the hardness of the matrix manganese steel. The selected inserts with different compositions and compaction pressures were casted and analyzed in the lab by using various characterization techniques including XRD and SEM. The effect of composition and pressure on the formation of TiC has been investigated, and the ultimate goal of this project was to find the best combination of composition and compact pressure to develop TiC reinforced manganese steels.
