Abstract: A high-hardness heat-resistant alloy comprising 13-17 wt % of Cr, 2-6 wt % of Al, 0.1-8 wt % of Mo, 1.5-3.5 wt % of B, 0.5-3 wt % of Ti, and 4-7 wt % of Co, the remaining components of the alloy being Ni and inevitable impurities. The alloy has high hardness and high strength at high temperatures and is therefore very suitable for use as a deposit or build-up welding material for exhaust valves in large low-speed diesel engines.

Abstract: The invention refers to a high temperature protective coating which is formed by an alloy of chromium, silicon, boron, iron and nickel. According to the invention, a light metal is mixed into the alloy as an additive. The additive consists preferably of aluminum. In addition, the silicon content of the high temperature protective coating is limited to 1.1 to 3.5 percent in weight relative to the total weight of the alloy.

Abstract: A method for achieving both improved high strength and improved ductility in intermediate phases is provided. The method, briefly stated, comprises the steps of providing a melt whose composition substantially corresponds to that of a preselected intermetallic phase having a crystal structure of the L1.sub.2 type, such as nickel aluminide, modified with from about 0.01 to 2.5 atomic percent boron, and rapidly solidifying the melt at a cooling rate of at least about 10.sup.3 .degree. C./second to form a solid body, the principal phase of which is of the L1.sub.2 type crystal structure in either its ordered or disordered state.
