- ItemOpen AccessMicrostructure and mechanical properties of TiAl/NiAl intermetallics processed by cryogenic mechanical milling(1995) McMinn, Neil A.; Mao, XingyuanCryogenic mechanical milling of intermetallic powders has been investigated as a means of producing new intermetallic materials. High energy milling of prealloyed titanium aluminide and nickel aluminide powders at liquid nitrogen temperatures results in stable non-equilibrium mixtures with a fine grain size. Subsequent consolidation by uniaxial hot pressing produces unusual intermetallic materials. Powders and consolidated materials are characterized using microscopy and x-ray diffraction. Mechanical properties are evaluated by small punch testing and through microhardness measurements. Fracture surfaces and modes are examined using Scanning Electron Microscopy.
