| Abstract | ||||
| ABSTRACT High chromium cast irons are widely used in many engineering practices where wear resistance is required. This paper studies the effect of titanium concentration on the wear behaviour of slightly hypoeutectic high chromium white cast iron. Other approach was investigated by adding other carbide forming elements such as manganese and molybdenum as a combination of two and three elements. The aim is mainly to see the influence of these elements on the toughness of the matrix, the smoothness of the structure as well as the wear properties of this kind of cast iron. Results, discussed in terms of the wear behaviour, shows that lower volume loss is seen for the sample having higher titanium content (3% Ti). This explains that titanium proeutectic carbide is the first phase precipitation during solidification which contributes to a reinforcement of the matrix. The formation of these carbides consumes parts of the carbon present in the alloy so that during eutectic solidification the volume of eutectic carbides diminished. The addition of manganese and molybdenum gives less important results. | ||||
