Residual stress measurement in dissimilar titanium and aluminium spot weld joints produced by Friction melt bonding
Titanium and aluminium assembly is of great interest in aerospace application due to its combination of high strength, light weight and good corrosion resistance. The large difference in their melting temperature, mechanical properties, corrosion potential and formation of brittle Ti/Al intermetallic compound (IMC) layer are major challenges and drawbacks to weld these two metals. Friction Melt Bonding (FMB) is a novel welding process patented at UCLouvain to join dissimilar metals with large differences in melting temperature. Our previous study at ILL (Proposal 1-02-212) helped to understand the residual stresses (RS) near the Al/steel interface produced by FMB. Original findings were disseminated in scientific communications. However, RS in Ti-Al weld joint is expected to be unique due to the large difference in CTE between Ti and Al and absence of phase transformation compared to that observed in steel. The spot weld geometry of the Ti-Al weld is also different to that of investigated Al/Steel like welds. Thus RS measurement remains crucial for these Ti-Al joints to develop fundamental understanding towards mitigation of mechanical and corrosion driven failure due to RS.
