Abstract

The invention provides a rapid solid solution and rapid multi-cooling variable-temperature aging heat treatment method. The rapid solid solution and rapid multi-cooling variable-temperature aging heat treatment method involves a rapid solid solution heat treatment process and a rapid multi-cooling variable-temperature aging heat treatment process. According to the scheme, the special heat treatment technical problems of "one long, one high, three poor and five low", namely, poor quality stability, low qualified product rate, low hardness, low mechanical property, poor consistency, long heating time, low efficiency, poor heating reliability of heat treatment equipment, short service life of high-temperature components, high cost and the like of austenitic stainless steel heat treatment can be solved.

Description

technical field [0001] The invention relates to the technical field of heat treatment of materials, in particular to a heat treatment method for fast solid solution and fast multiple times of temperature-changing and aging heat treatment. 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 aging heat treatmen...
