Abstract

The invention provides a rapid solid solution and rapid starting from high-temperature multi-time variable-temperature alternating aging heat treatment method. The heat treatment method comprises a rapid solid solution heat treatment process and a rapid starting from high-temperature multi-time variable-temperature alternating aging heat treatment process. According to the scheme, the problems that mainstream austenitic stainless steel solid solution and aging heat treatment are poor in quality stability, low in qualified product rate, low in hardness, low in mechanical property, poor in consistency, long in heating time, low in efficiency, heat treatment equipment is poor in heating reliability, components are short in service life, the cost is high, and other special heat treatment technology theories and practice problems are solved.

Description

technical field [0001] The invention relates to the technical field of heat treatment of materials, in particular to a rapid solid solution and rapid starting from high temperature multiple times variable temperature alternating aging heat treatment method. Background technique [0002] The heat treatment principles of austenitic stainless steel and alloy structural steel are completely different: alloy structural steel can undergo high-temperature austenite transformation under high temperature conditions. Therefore, alloy structural steel can easily increase the hardness of the material through quenching and tempering heat treatment methods ( or mechanical properties); and austenitic stainless steel cannot undergo high-temperature austenite structural transformation under high temperature conditions (only the strengthening phase of alloying elements can be dissolved and precipitated), so it is extremely difficult for austenitic stainless steel to undergo solid solution and ...
