Elastic Constants of Co3Ti and CoTi Intermetallic Compounds

The elastic constants of both the L12 type (Co, Ni)3Ti and the B2 type CoTi compounds were measured at room temperature by a rectangular parallelepiped resonance (RPR) method. The elastic constants, c11, c12 and c44, of (Co, Ni)3Ti are 228, 148 and 129 GPa, respectively, while those of CoTi are 203,...

More Information
Summary:The elastic constants of both the L12 type (Co, Ni)3Ti and the B2 type CoTi compounds were measured at room temperature by a rectangular parallelepiped resonance (RPR) method. The elastic constants, c11, c12 and c44, of (Co, Ni)3Ti are 228, 148 and 129 GPa, respectively, while those of CoTi are 203, 129 and 68 GPa. The elastic anisotropy of the (Co, Ni)3Ti is large (A=3.23), while that of the CoTi is relatively small (A=1.83).
