Mechanical properties and deformation behaviour of laminated titanium-intermetallic composites synthesised using Ti and Cu foils

Abstract: Ti-intermetallic laminated composites were fabricated via reaction synthesis in vacuum using foils of titanium and copper with controlled temperature, treating time and pressure. Microstructural examinations using SEM and EDX demonstrated that copper layers were completely consumed and five intermetallic compounds: Ti2Cu, TiCu (predominant phase), Ti3Cu4, Ti2Cu3 and TiCu4 were formed. The mechanical properties and fracture behaviour of the fabricated composites were examined. The results showed that treating t… Show more

“…The properties and reliability of clad composite are dependent on the interface properties. The ductility of clad does not increase in case the interface bonding strength is low because of the interface flaws, voids and brittle intermetallics [8,9].…”

“…Aluminium, copper, silver and their alloys were used previously as intermediate materials [13][14][15][16]. The literature survay shows that the copper layer of 0.1 mm thickness effectively blocks the diffusion of titanium to stainless steel only up to 900°C and if the bonding time is no longer than 30 minutes [17,18]. Previous attempts [19] and literature data [20,21] report that pure nickel and nickel alloys also may be considered The faces of the cylinders were prepared by conventional grinding and polishing techniques and final polishing was made with 0.5 μm alumina suspension.…”

“…Konieczny (2010) produziu compósitos de titânio com intermetálicos Ti-Cu e obteve durezas de 783 e 681 HV para as fases TiCu e TiCu2, respectivamente, enquanto uma mistura dos compostos TiCu4, Ti2Cu3 e Ti3Cu4 apresentou dureza de 530 HV. Comparativamente, a matriz de titânio neste mesmo estudo apresentou dureza de 273 HV (KONIECZNY, 2010). A Tabela 2 reúne as informações cristalográficas das fases presentes no diagrama de equilíbrio do sistema Ti-Cu.…”
