Embodiment

[0012] The materials of the invention include Al-Ti alloy, Al-B master alloy, pure silicon, pure magnesium, pure aluminum and Al-5%Ti master alloy produced by electrolytic method. According to the proportion of Ti, B mass ratio greater than 2.22:1 (Ti excess 0.1%), prepare raw material alloy and corresponding amount of pure silicon and pure magnesium, for the preparation of TiB2 The mass percentage content is 0.5%, 1.0%, 1.5%, respectively. 2.0% and 2.2% test alloys. Alloy preparation was carried out in a 7.5kW crucible resistance furnace. The specific preparation process is: put the electrolytic Al-Ti alloy, pure magnesium, and pure silicon together into a graphite crucible, heat and melt, and raise the temperature of the melt to 750 degrees, add the Al-B master alloy after fully stirring, Proper stirring is carried out during the melting process to ensure that Ti and B atoms can fully react, and Al-5%Ti master alloy and pure aluminum are used to adjust the content of titani...

Abstract

The invention discloses a TiB2 / Al-Si-Mg alloy. The TiB2 / Al-Si-Mg alloy improves alloy mechanical properties and satisfies industrial requirements. Raw materials of the TiB2 / Al-Si-Mg alloy comprise an Al-Ti alloy produced by an electrolytic method, an Al-B intermediate alloy, pure silicon, pure magnesium, pure aluminum and an Al-5%Ti intermediate alloy. According to a mass ratio of Ti to B of more than 2.22: 1, the raw material alloys and a corresponding amount of the pure silicon and pure magnesium are prepared and are used for preparation of an alloy with 1.0% by mass of TiB2. The alloy preparation is carried out in a pot resistance furnace with power of 7.5kW.

Description

technical field [0001] The invention relates to a TiB2 / Al-Si-Mg alloy and belongs to the technical field of alloy performance optimization. Background technique [0002] The direct electrolysis of Al-Ti alloy by adding TiO2 powder into the aluminum electrolytic cell has been studied for many years. The results show that the production of Al-Ti alloy by electrolysis has high Ti recovery rate, easy control of composition, and uniform distribution of Ti in the melt. , Low production cost and so on. But its mechanical properties can not meet the industrial requirements well. Contents of the invention [0003] The problem to be solved by the present invention is to provide a TiB2 / Al-Si-Mg alloy aimed at improving the mechanical properties of the alloy to meet industrial requirements. [0004] Technical scheme of the present invention: [0005] A TiB2 / Al-Si-Mg alloy, the material includes Al-Ti alloy, Al-B master alloy, pure silicon, pure magnesium and pure aluminum and Al-5%...
