Steel Matrix Composite

Hadfield steel matrix composite, reinforced by high-chromium (Cr) cast iron bars, was fabricated by inserting high-Cr alloy flux-cored welding wires into Hadfield steel molten at 1500 °C. The characteristics for water-quenched composite were investigated and compared with those of reference Hadfield steel. The results show that flux-cored welding wires could be melted by heat capacity of Hadfield steel molten and transformed into high-Cr cast iron bar reinforcements after solidification. The reinforcements of water-quenched composite consist of martensite, eutectic M7C3 carbides and residual austenite. With the increasing of impact energy, the impact wear rate of the composite firstly decreases, and then increases slightly, therefore, the composite is more available to the conditions of low and medium impact energy. The reason is it can combine fully advantages of the outstanding toughness of Hadfield steel, and high hardness of high-Cr cast iron.

Abstract Wear resistance of TiC-cast steel metal matrix composite has been investigated. Composites were obtained with SHSB method known as SHS synthesis during casting. It has been shown the differences in wear between composite and base cast steel. The Miller slurry machine test were used to determine wear loss of the specimens. The slurry was composed of SiC and water. The worn surface of specimens after test, were studied by SEM. Experimental observation has shown that surface of composite zone is not homogenous and consist the matrix lakes. Microscopic observations revealed the long grooves with SiC particles indented in the base alloy area, and spalling pits in the composite area. Due to the presence of TiC carbides on composite layer, specimens with TiC reinforced cast steel exhibited higher abrasion resistance. The wear of TiC reinforced cast steel mechanism was initially by wearing of soft matrix and in second stage by polishing and spalling of TiC. Summary weight loss after 16hr test was 0,14÷0,23 g for composite specimens and 0,90 g for base steel.
