Abstract
A method of producing a microstructure of a high-alloy steel includes heating the metal stock to a temperature between 1270° C. and 1280° C., at a rate between 40° C./s and 45° C./s, followed by compression applied to the metal stock in a thixotropic process, after which the stock is cooled to ambient temperature. A microstructure is also shown, which includes undissolved metal carbides in the form of globular particles of austenite microstructure and of martensite microstructure.
