Abstract

Phase content and temperature dependences of cell parameters for intermetallics HfNi2Al5, Hf6Ni8Al15 and Ni2Al3, existed in Al-Ni-Hf ternary system have been studied by means of X-ray diffraction method. Experimental values of cell parameters at different temperature were used to calculate the thermal expansion coefficients and their temperature dependences. It is shown that for intermetallic phase with cubic structure temperature dependence of thermal expansion coefficient is significantly different than for l one with tetragonal structure.
