However, the percentage of dissolved eutectic carbides is also higher. Heat Treatments of Austenite in High Chromium White Cast Iron, Alloyed with Mo.

High-chromium white cast irons are ferrous alloys containing 11-30% Cr and 1.8-3.6% C along with variable amounts of molybdenum, manganese, copper and nickel [1]. The standard procedure most commonly used for the classification of this kind of cast iron

High chromium cast iron is the third generation of white cast iron developed from ordinary white cast iron and hard nickel cast iron. The chromium content of high chromium white cast iron is more than 11%, and the ratio of chromium to carbon is between 4~8. Under these conditions, M7C3 type carbides with high hardness almost completely replace

Microstructure. e microstructure of as-cast high chromium white cast iron with no Ti-addition consists of M 7 C 3 carbides that form during solidi cation as eutectic phase (a mixture of M 7 C 3 and austenite) a er the for-mation of proeutectic austenite dendrites ( Figure ). In an earlier study, Ibrahim and Nofal [ ]discussedbrie ythe

12/1 · Correlation of microstructure with the wear resistance and fracture toughness of duocast materials composed of high-chromium white cast iron and low-chromium steel

The invention relates to wear-resistant white cast iron and a method for preparing the same, in particular to hypereutectic high-chromium white cast iron and a method for preparing the same. The castiron is suitable for preparing an overflow part (such as an impeller, a guard board, a shell and so on) of a slurry pump or a Yellow River water pump for conveying eroding and abrading slurry.

High chrome white iron cast alloy's superior wear resistance is due primarily to a high volume fraction of very hard, well-dispersed primary and secondary carbides in a matrix of martensite. The high chromium content provides good resistance in corrosive environments and good oxidation resistance. COMPOSITION C % 2.0 - 3.5 Mn % - 1.5 max.

A highly abrasion-resistant, high-chromium white cast iron alloy containing the following elemental analysis in percent by weight: 2.4-3.8% carbon, 

MICROSTRUCTURE AND PROPERTIES OF HIGH CHROMIUM WHITE CAST IRONS ALLOYED WITH BORON. high chromium white cast iron, boron, microhardness, hardness, 

microstructure of high chromium white cast irons leading to secondary carbide precipitation of. different extent and nature.

High-Chromium White Irons, The high-chromium white irons have excellent abrasion resistance and are used effectively in slurry pumps, brick molds, coal-grinding mills, shot-blasting equipment, and components for quarrying, hard-rock mining, and milling. In some applications they must also be able to withstand heavy impact loading.

11/15 · High chromium white cast iron (HCWCI) is considered a hard machinable material because of its high carbide content, which when associated with a matrix, forms a rigid and

Abstract. To determine the effect of austenite stabilizer element on the microstructure and behaviour of as–cast high Cr white cast iron 

Over the years it has become apparent that even though high-chromium white cast irons are highly efficient abrasion-resistant material, a combination of 

9/22 · The chromium in high chrome white iron reduces the cooling rate required to produce carbides throughout the material, allowing massive castings to be manufactured with

According to the invention, the crystal grains of the processed cast iron Cr28 are refined, and alloy elements in tissues are more uniform. Especially, characteristic points with high hardness and high wear-resistance in the alloy are converted from thick strips into spheres, such that impact toughness is improved, and service life is prolonged.

Whit cast irons, and specifically high chromium white cast irons, have been developed and deployed worldwide for making mechanical components of crushing 

diagrams (i.e. isoplethal maps) of high chromium white cast irons (~19% in weight) with different molybdenum contents were simulated.

9/4 · The initial as-cast structure of a high-chromium white iron consisted of primary austenitic dendrites and a eutectic mixture of M 7 C 3 /austenite. Cr depletion of the matrix in the close vicinity of the carbide particles had led to their engulfment by a thin martensite layer.

Superior abrasive wear resistance, combined with relatively low production costs, makes high Cr white cast irons (WCIs) particularly attractive for applications
