2) titanium alloy component after cleaning is placed on the base of fixture and positions, and is depended on holding down assembly by the briquetting assembly of fixture Secondary location is placed on titanium alloy component, uses the voussoir of fixture to holding down assembly, briquetting assembly, titanium alloy component and base enter Compression joined by luggage,
3) fixture that will be equipped with titanium alloy component is put in vacuum heat treatment furnace, carries out evacuation,
4) after evacuation, vacuum heat treatment furnace is warming up to 300 degree, keeps 30 minutes after furnace temperature is stable,
5) it is warming up to 640-660 degree the most again, keeps 90 minutes after furnace temperature is stable,
6) carry out again after stove is cooled to 280-200 degree, opening vacuum heat treatment furnace, making the fixture air cooling of assembling titanium alloy component to room Temperature,
7) titanium alloy component is taken out from fixture, obtain qualified titanium alloy component.
Described titanium alloy component is stablized in heat treatment process method, and the base of described fixture has shape face, and described shape face is with qualified Titanium alloy component match, described titanium alloy component is placed on described shape face, and the periphery of described base is provided with lifting assembly.
Described titanium alloy component is stablized in heat treatment process method, and the periphery that holds down assembly of described fixture is provided with lifting bolt, pressure Tight assembly is by crossbeam and the network structure of vertical beam staggered, the shape face that described network structure is constituted and qualified titanium alloy component Match.
Described titanium alloy component stablizes heat treatment process method, and the material of described fixture is TA15 titanium alloy or rustless steel.
One titanium alloy component of the present invention is stablized heat treatment process method and is had the advantages that
The inventive method efficiently solves machined, chemistry milling, deposits after panel beating or welding processing in titanium alloy component In the problem that residual stress and organizational structure are uneven, it is ensured that the physical dimension of titanium alloy component and the performance of product, meet titanium The requirement that alloy part works under specific environment such as high temperature.Use special fixture clamping titanium alloy component in the methods of the invention, Not only ensure that geometry and the dimensional accuracy of titanium alloy component, the also titanium alloy zero to the most formed not met required precision Shape and the geometric parameter of part are modified, and improve the precision of titanium alloy component, make titanium alloy component meet drawing requirement.
Accompanying drawing explanation
