The present invention is a wear-resistant member using a Cr-based alloy material, in which the Cr-based alloy material includes: more than 40 mass % and 65 mass % or less of Cr; 15 mass % or more and 40 mass % or less of Ni; more than 0 mass % and 30 mass % or less of Fe; 5 mass % or more and 16 mass % or less of Nb; 0.1 mass % or more and 0.9 mass % or less of Ti; 0.6 mass % or more and 2.5 mass % or less of C; 2 mass % or less of Mn; and impurities, and in which a mass ratio Ti/Nb of the Nb and the Ti is 0.063 or less.

A method of fabricating of an object includes causing a first heat source to heat a feed material to form a melt pool of the feed material on a surface. The method further includes causing a second heat source to heat the melt pool on the surface to regulate grain formation of the feed material in the melt pool as the melt pool cools and solidifies on the surface to form at least a portion of the object. The method also includes causing the first heat source and the second heat source to move relative to the surface as the melt pool is formed and cooled.

In various embodiments, additive manufacturing is utilized to fabricate three-dimensional metallic parts using metallic alloy wire as a feedstock material.

A welding method using coated abrasive particles, coated abrasive particles, coating system and sealing system which uses particles, in which a hard material layer is applied around abrasive particles such as cubic boron nitride (cBN) and protects against oxidation during welding. The hard material compound in the coating may include a carbide, in particular titanium carbide. A sealing system is composed of stator and rotor blade having the layer system.

The present invention relates to a method of producing a composite rod from a braze material and a sheet of material comprising cermet. The method comprises scoring a surface of the sheet to produce at least one line of localised stress and subsequently causing the sheet to break along the line or localised stress, thereby to produce a plurality of cermet chunks. The cermet chunks can be combined with the braze material to produce the composite rod. In a particular embodiment, the sheet of material may be a used cermet cutting tip.
