Horizontal vacuum furnace titanium alloy part solid solution component and jig

Abstract

The invention belongs to the field of titanium alloy part strengthening, and particularly relates to a horizontal vacuum furnace titanium alloy part solid solution component and a jig. The component comprises an inner framework, a peripheral framework and four steel tube sleeve pieces, wherein both the inner framework and the peripheral framework take the shapes of cuboids with openings; the innerframework is arranged inside the peripheral framework; the four steel tube sleeve pieces are separately arranged at four inner corners of the peripheral framework; and each steel tube sleeve piece comprises a steel tube arranged on the inner side of the peripheral framework and a stainless steel rod arranged in the steel tube. After the jig is used for performing solid solution treatment, the mechanical property of titanium alloy meets requirements, and oxidation phenomenon does not occur.

Description

technical field [0001] The invention belongs to the field of strengthening titanium alloy parts, and in particular relates to a solid-solution component and tooling of titanium alloy parts in a horizontal vacuum furnace. Background technique [0002] Solid solution is the main means of strengthening titanium alloy parts. In order to ensure the solid solution strengthening effect, the parts need to be transferred to the cooling liquid (water) for cooling as soon as possible after the solid solution heat preservation is completed, so as to prevent the parts from cooling down too much before cooling in the cooling liquid (water). [0003] Moreover, since titanium alloy is extremely easy to oxidize, it cannot be directly contacted with air during the solid solution process, and can only be carried out in a vacuum atmosphere or an inert gas atmosphere. [0004] At present, the more common equipment for heat treatment of titanium alloy parts is the horizontal vacuum heat treatmen...

AI Technical Summary

Problems solved by technology

Its characteristic is that the solid solution transfer time takes about 15 seconds. During this process, the temperature of the parts has dropped a lot, which seriously affects the solid solution effect of the parts, and the mechanical properties often fail in batches.

[0005] In addition, in the process of vacuum solid solution, the vacuum degree of the equipment will occasionally be out of tolerance, resulting in oxidation of titanium alloy parts, resulting in batch scrapping
