The work involves estimation of elastic, ultrasonic and thermo-physical properties of YM (Y: Yttrium, M=Zn, Cu, Ag) intermetallics at 300 K. Initially, second order elastic constants and elastic modulus of chosen intermetallics are determined in temperature range 300K-1200K under potential model approach. Later, the ultrasonic velocities are calculated using second order elastic constants and densities for wave propagation along <100>, <110> and <111> crystallographic directions. Additionally, Debye temperature, specific heat at constant volume, thermal conductivity and thermal relaxation time are also calculated. The analysis reveals that compound YCu incorporates better mechanical and thermal properties than the other two compounds.Keywords
