Fatigue crack growth behavior has been examined in a particulate titanium diboride (TiB2)–reinforced iron-based composite that had been produced via a mechanical alloying process. Comparison with equivalent unreinforced material indicated that fatigue crack growth resistance in the composite was superior to monolithic matrix material in the near-threshold regime. The composite exhibited relativ...

Nanocomposite of titanium diboride/titanium carbide was fabricated by combustion synthesis of mechanically milled reactant powders. The stoichiometric mixture of Ti and B4C as starting materials milled for 1, 3, 6 and 9 h. Milled powders pressed to form pellets then green compacts were placed in a tube furnace that preheated to 1100 oC in inert atmosphere (Ar).The samples were investigated by X...

Titanium matrix composites (TMC) represent a perspective materials category with potential applications in many important fields like aerospace constructions, automotive industry, ship structures, sports and households objects, and others. A titanium matrix composite is constituted of a titanium or titanium alloy – matrix and reinforcements materials, which are usually ceramics in form of parti...
