Elastic properties of B2-ordered NiAl and NiAl–X (Cr, Mo, W) alloys

The elastic properties of unidirectionally solidified and of axisymmetrically deformed quasi-binary eutectic NiAl–34Cr, NiAl–9.5Mo and NiAl–0.95W alloys have been investigated by taking single crystal elastic stiffness coefficients, Young's moduli and preferential fibre texture components into account.Also the temperature dependence of Young's moduli of the axisymmetrically extruded rods are described and quantitatively discussed based on the model of harmonic lattice vibrations. The experimentally obtained data are in good agreement with the predicted ones.
