The present work incorporates computation of elastic, ultrasonic and thermal properties of B2 structured AuRE (RE= Sm, Tb, Ho, Tm) intermetallics in temperature range 300K-900K. Initially, elastic constants are determined under potential model approach. Later on, ultrasonic velocities are obtained in the same temperature range for wave propagation along and crystallographic directions. Besides it, Debye temperatures, thermal energy density, thermal expansion coefficient and melting temperature are also determined for chosen intermetallics. The obtained results are compared and analyzed to explore the inherent properties the chosen material.Keywords
