Problems solved by technology

In the high-temperature aluminum melt, add potassium fluotitanate and potassium fluoborate compounds, and use the reduction reaction between the aluminum liquid and these two compounds at high temperature to obtain an aluminum-titanium-boron master alloy with a composition of 2% to 3%. , patents CN201711352357.6, CN201711166867.4, CN201210093195.X, etc. all use the chemical reaction of potassium fluorotitanate and potassium fluoroborate in aluminum liquid to obtain aluminum-titanium-boron intermediate alloys. The content of titanium and boron in these alloys is limited. The content of titanium is 1% to 10%, and the content of boron is 0.5 to 5%, both of which are used as grain refiners for aluminum alloys. This method cannot be used to prepare aluminum-titanium-boron alloy targets with high titanium and boron content.

Abstract

The invention provides an Al-Ti-B target material and a powder solid phase alloying sintering method thereof. The method comprises the following steps of firstly, weighing and mixing, secondly, ball grinding mechanical alloying, thirdly hot pressing sintering, fourthly, demolding, fifthly, annealing treatment and sixthly, forging. According to the Al-Ti-B target material and the powder solid phasealloying sintering method thereof, high-content Ti and B are added into an Al matrix to be prepared into the Al-Ti-B target material, the content of Ti can reach up to 80%, and the content of B can reach up to 20%; on the basis of an Al-Ti-B ternary alloy, other elements can be added to obtain the alloy target material with more elements; due to the fact that the low temperature and large pressure solid phase sintering method, melting and flowing of low-melting-point alloy elements are avoided, and through the diffusion action, alloying between high-melting-point alloy elements and low-melting-point alloy elements is achieved; and the technological process is short, product quality is stable, production cost is low, and the Al-Ti-B target material and the method are suitable for batched production.
