Embodiment Construction

[0021] A processing method for stable heat treatment of titanium alloy parts, comprising the steps of:

[0022] 1) Clean the titanium alloy part 6 with acetone,

[0023] 2) Place the cleaned titanium alloy part 6 on the base 2 of the jig for positioning, position the pressing block assembly 3 and the pressing assembly 1 of the jig on the titanium alloy part 6 in sequence, and use the wedge 4 of the jig to press Tightening component 1, briquetting component 3, titanium alloy part 6 and base 2 are assembled and pressed,

[0024] 3) Put the clamp equipped with the titanium alloy part 6 into a vacuum heat treatment furnace to vacuumize,

[0025] 4) After vacuuming, raise the temperature of the vacuum heat treatment furnace to 290-310 degrees, and keep it for 30 minutes after the furnace temperature is stable.

[0026] 5) Then heat up to 650 degrees, and keep the furnace temperature for 90 minutes after it stabilizes.

[0027] 6) After the furnace is cooled to 280-200 degrees, t...

Abstract

The invention provides a stable heat treatment processing method for titanium alloy parts, which uses a stable heat treatment fixture to process titanium alloy parts, which effectively solves the problems of residual stress and uneven structure in titanium alloy parts after processing, thereby ensuring the structural size of titanium alloy parts and product performance.

Description

technical field [0001] The invention relates to a processing method for stabilizing heat treatment of titanium alloy parts, which is mainly used for correcting processed titanium alloy parts, reducing or eliminating residual stress of aircraft titanium alloy parts, and improving the structure stability of titanium alloy. Background technique [0002] At present, after mechanical processing, chemical milling, sheet metal processing or welding processing, aircraft titanium alloy parts can obtain parts with corresponding structure and size, which can be directly used in the production of products. However, residual stress will inevitably be generated in the process of processing, and there will be uneven structure in parts, which will even affect the precision of titanium alloy parts. However, if the residual stress and uneven structure in titanium alloy parts cannot be dealt with in time, they will be gradually released over time, thus affecting the structural size of titanium...
