Third-order elastic constants of bcc Cu-Al-Ni.

We have measured the changes in the ultrasonic wave velocity, induced by the application of uniaxial stresses in a Cu-Al-Ni single crystal. From these measurements, the complete set of third-order elastic constants has been obtained. The comparison of results for Cu-Al-Ni with available data for other Cu-based alloys has shown that all these alloys exhibit similar anharmonic behavior. By using ...

Elastic constants of bcc Cu-Al-Ni alloys.

We have measured the adiabatic elastic constants of two Cu-Al-Ni martensitic alloys using ultrasonic methods and we have compared the results to recent neutron-scattering experiments. It is shown that the elastic behavior of Cu-Al-Ni alloys follows the same trends exhibited by other Cu-based alloys; in particular, the TA2 long-wavelength acoustic modes are softer than all other modes. Disciplin...

Second Order Elastic Constants, Third Order Elastic Constants, Pressure Derivatives of Second Order Elastic Constants and the Low Temperature Thermal Expansion of D-tin

The complex behaviour of metals under severe thermal and stress environments is influenced markedly by their elastic properties. Indeed the response of a material tc~ an applied stress is always determined by the elastic constants and their pressure derivatives. Furthermore, both the mechanical and thermodynamic equation;$ of state of a metal that contains dislocations require detailed knowledg...

New Estimates of the Third-order Elastic Constants for Isotropic Aggregates of Cubic Crystals

An improved method, based on an extension of the self-consistent method from the linear theory, is proposed to evaluate the effective third-order elastic constants for isotropic aggregates of cubic crystals. The calculated constants are compared with the Voigt and Reuss-type estimates, which are currently the only other analytical estimates available for these constants. The agreement between c...

Elastic constants of Ni-Mn-Ga magnetic shape memory alloys

We have measured the adiabatic second order elastic constants of two Ni-Mn-Ga magnetic shape memory crystals with different martensitic transition temperatures, using ultrasonic methods. The temperature dependence of the elastic constants has been followed across the ferromagnetic transition and down to the martensitic transition temperature. Within experimental errors no noticeable change in a...
