Dissimilar joining of titanium to aluminum is required for several purposes in automotive and aerospace industries. Nevertheless, a number of issues arise due to their different properties, in terms of crystal micro structure, melting point, heat conductivity and coefficient of linear expansion. In addition, brittle intermetallic formation is induced at the interface, thus affecting the...$28.00
