Analytical study to effects on reflection coefficient of Ti-Mn alloys at increasing concentration Mn element in the...

Manganese (Mn) is one of the trace elements in the human body, The titanium-manganese (TiMn) alloys have been used in some applications as well. The TiMn alloys with various manganese contents ranging from 2 to 12 wt % were prepared by using mechanical alloying and spark plasma sintering (SPS) techniques (Sibum, 2003)^. This paper investigated the effects of increasing manganese content in the Ti. Concentrations of Mn (2 wt % to 12 wt %) in titanium influence the reflection coefficients and acoustic signatures of Ti-Mn alloys by Scanning Acoustic Microscopy (SAM) technique, was determined by The oscillatory behavior, The spectral treatment of these signatures, via fast Fourier transform. Correspond to longitudinal and Rayleigh relations depend on Mn Concentrations, was Concluded that Mn Concentrations (from 2 wt % To 12 wt %) increase with increasing Bulk physical properties and Acoustic wave velocities (AWV) as Young's Modulus, Shear Modulus, Bulk modulus, Longitudinal Velocity, Transverse Velocity, and Rayleigh Velocity were (from 105 To 122)Gpa, (from 39.6 To 45.9)Gpa, (from 103 To 119.6)Gpa, (from 4862 To 6183) ms¹, (from 2450 To 3115)ms^-1and (from 1658 To 2064)ms^-1 respectively.
