摘要
The static and cyclic fracture toughnesses of a Ti–Al3Ti–Al–Al3Ti laminate composite material containing at most 15 vol % intermetallic compound are studied. Composite specimens are prepared by terminating reaction sintering of titanium and aluminum foils under pressure. The fracture of the titanium layers is quasi-cleavage during cyclic crack growth and is ductile during subsequent static loading. © 2015, Pleiades Publishing, Ltd.
