    摘要： A heterogeneous composite body that is spall resistant and comprises a substantially discontinuous cermet phase in a substantially continuous metal rich matrix phase. The heterogeneous composite body is typically bonded to a substrate to form a hardfacing on the substrate. The heterogeneous composite body exhibits ductile phase toughening with a strain to failure of at least about 2 percent, a modulus of elasticity of less than about 35 million pounds per square inch, and a density of less than about 7 grams per cubic centimeter. The metal rich matrix phase between the ceramic rich regions in the heterogeneous composite body has an average minimum span of about 0.5 to 8 microns to allow ductility in the heterogeneous composite body. The heterogeneous composite body has a Vicker's hardness number of greater than approximately 500. The ceramic rich regions exhibit high hardness as compared with the matrix phase.

    摘要： A coating steel component with a pattern of an iron based matrix with crystalline particles metallurgically bound to the surface of a steel substrate for use as disc cutters or other components with one or more abrading surfaces that can experience significant abrasive wear, high point loads, and large shear stresses during use. The coated component contains a pattern of features in the shape of freckles or stripes that are laser formed and fused to the steel substrate. The features can display an inner core that is harder than the steel substrate but generally softer than the matrix surrounding the core, providing toughness and wear resistance to the features. The features result from processing an amorphous alloy where the resulting matrix can be amorphous, partially devitrified or fully devitrified.
