HIGH PERFORMANCE MACHINING OF HIGH CHROMIUM WEAR ...

2004). High chromium white cast irons are among the typical wear-resistant materials in which the white cast iron alloyed with 12 – 35 % chromium for achieving superior wear resistance and corrosion resistance (Pearce,1983; Tabrett,1996). The materials offer good corrosion resistance and high abrasion resistance as the result of high concentration of chromium in the matrix and the presence of eutectic carbides (M 7 C 3

Metallurgical Aspects of HIGH- CHROMIUM WHITE IRONS

Structure developed by the heat treatment of a high-chromium iron. Specimen from a chute liner 50 mm thick, containing 2.6% total carbon, 1.5% Si, 1.1% Mn, 14.3% Cr, and 3.0% Mo, reheated to 1040 to 1065 C and air cooled. Structure is M7C3eutectic carbides in

Wear resistance of high chromium white cast iron for coal ...

High chromium white cast iron alloy used in coal grinding components is a material that may present different wear resistance depending on the thermal treatment used in its manufacturing. In this context, the properties of this alloy, containing 22% chromium and 3% carbon, were investigated after applying different heat treatments and their influence on the abrasion wear resistance was evaluated. For the

Heat treatment process of the high chrome cast iron ...

The microstructure of high chromium white cast iron grinding ball as-cast and after heat treatment was observed by metallographic microscope. The sample of 10mm* 10 mm* 8 mm in size at the center of the grinding ball was cut by weld and polished with 200 # to 1500 # metallographic sandpaper. The etching agent was 4% nitric alcohol and the etching time was 10S. The microstructure was observed

Two- and three-body abrasive wear behaviour of

29/09/2000  The microstructure of the three differently cooled high chromium boron-added cast iron specimens can be characterized as eutectic carbides distributed in a matrix of martensite. However, secondary carbides can be also seen in the matrix. Eutectic carbides were identified by using X-ray diffractometer as of M 7 C 3 type.
