The shock Hugoniot of the intermetallic alloy Ti–46.5Al–2Nb–2Cr

Abstract: Temperature dependent reflectivity and anisotropic magnetization reversal in magnetically doped quasi-twodimensional charge density wave alloys A 0.01 Nb Se 2 ( A = Cr , Mn , Fe ) J. Appl. Phys. 103, 07D306 (2008); 10.1063/1.2856509Shear strength measurements in the TiAl-based alloy Ti-48Al-2Nb-2Cr-1B during shock loadingPlate impact experiments were conducted on a ␥-titanium aluminide ͑TiAl͒ based ordered intermetallic alloy. Stress measurements were recorded using manganin stress gauges supported on the back… Show more

“…Ti-Al alloys are attractive for a broad range of applications to aerospace and automobile engines due to their high strength, high melting temperature, desirable oxidation and creep resistances, combined with low density [2][3][4]. Investigations on the thermophysical properties of such an alloy system in the liquid state are necessary for their future development.…”

“…However, this method does not account for differences between the structures of the components (Ni, face centred cubic and Ti, hexagonal close packed) and the product (ordered body centred cubic, B2), changes in the nature of bonding or even the effects of the martensitic shape memory effect itself. We have used this method previously [14] to determine the Hugoniot of a titanium aluminide from known elemental data, showing that there was a significant difference between the measured and calculated Hugoniots. Therefore, it is only with great caution that such methods should be employed.…”

“…Steif et al 1 simulated impact on TiAl compressor blades by firing steel spheres at thin plates of a titanium aluminide. In a material of composition Ti-46.5Al-2Nb-2Cr, 4 the Hugoniot was determined and was found to be significantly steeper than that of the common engineering alloy Ti-6Al-4V. Ikebuchi et al 2 studied the deformation structure of TiAl by impacting a copper cylinder at velocities of between 0.6 and 1.6 km s Ϫ1 on smaller targets.…”
