Three types of Al-5Ti master alloys were synthesized by a method of thermal explosion reaction in pure molten aluminum. Performance comparison of Al-5Ti master alloy in grain refinement of commercial purity Al with different additions (0.6%, 1.0%, 1.6%, 2.0%, and 3.0%) and holding time (10, 30, 60 and 120 min) were investigated. The results show that Al-5Ti master alloy with blocky TiAl₃ partic...

Abstract Ti/Al bimetallic structure (BS) has a good development prospect and broader application potential in aerospace engineering. Considering the limitation that dissimilar welding is only applicable to thin plate, it necessary explore new manufacturing process for BS. In this study, TC4/AlSi12 BS was prepared by laser additive (LAM). TC4 zone, AlSi12 zone transition were formed LAM process....

We consider the Gamma limit of the Abelian Chern-Simons-Higgs energy
