dc.description.abstractPolycrystalline alloys of iron in vanadium up to 15.32 atomic percent were prepared principally by arc melting. In order to obtain the elastic constants and investigate the possibility of the existence of an elastically isotropic alloy supersonic measurements were made. These measurements determined the longitudinal and transverse wave velocities in the 10-30 MHz range at room temperature. The resulting longitudinal modulus increased with alloying whereas the shear modulus remained roughly constant although the data are somewhat scattered. These data are interpreted to show that the shear constants vary through alloying in a manner consistent with the results of other experiments and that the results are consistent with a s(1) d(n+1) electronic configuration in the transition metals. The existence of an isotropic alloy is indicated for alloys with electron to atom ratios lower than vanadium rather than for the alloys measured.en_US
