The fundamental kinetic difference between the transformation of high-speed steel on heating by high-frequency inductive current and on quenching in salt baths is considered. In heating by high-frequency current, the high temperature at the carbide–matrix boundary permits more complete carbide solution in the austenite. That improves tool quality.
