Abstract

The invention relates to a production method of a titanium-aluminum alloy target. The method includes the steps of firstly, adding titanium powder and aluminum powder into a V-shaped mixer for mixing; secondly, placing the powder in an isostatic cool pressing capsule, vacuumizing in prior to sealing, pressing for 10-20 minutes, and placing in a vacuum self-propagating high-temperature synthesis furnace for self-propagating reaction to obtain foamed titanium-aluminum alloy; thirdly, crushing the alloy into 200-mesh powder, placing in an isostatic cool pressing capsule, and pressing to obtain titanium-aluminum alloy billets; fourthly, placing the alloy billets in a steel capsule, and vacuum degassing in prior to hot isostatic pressing sintering to obtain titanium-aluminum alloy ingots; and fifthly machining to obtain the finished titanium-aluminum alloy target. Due to the fact that the method adopts the second step for alloying after well mixing of raw materials and before hot isostatic pressing sintering and conditions of each step are strictly controlled, the prepared titanium-aluminum alloy target is high in density and even in crystallite size distribution.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a production method of a titanium-aluminum alloy target. Background technique [0002] Titanium-aluminum alloy has low density, high specific strength, high specific stiffness, good heat resistance, high temperature creep resistance and oxidation resistance. It is a lightweight superalloy with the best comprehensive performance. The material of choice for the next generation of advanced aero-engines has therefore become the focus of research in lightweight alloys. Titanium-aluminum alloys can be mainly divided into three types, namely Ti3-Al, Ti-Al and Ti-Al3. Among them, Ti3-Al has poor high-temperature oxidation resistance and low service temperature (≤650°C); Ti-Al3 has the lowest density and the best high-temperature oxidation resistance, but because the solid solution range is too narrow, the ductility at room temperature is poor. Machining is difficult. ...
