A Novel Method of Fabricating Al-V Intermetallic Alloy through Electrode Heating

A Novel Method of Fabricating Al-V Intermetallic Alloy through Electrode Heating

A novel method was developed to produce AlV55 alloy through reducing impurities content and component segregation with electrode assisted heating technology. This new process synergistically integrates a few low-cost process techniques, including granulation, mixing, and electro-heating to produce A...
