| Popis: | The microstructure and mechanical properties of TiNiFe alloys with different compositions was investigated by tensile test, X-ray diffraction, EBSD, SEM, and TEM. The results indicated that tensile strength rapidly increased with increasing Ni content. In addition, Ti2(Ni,Fe) particles were observed in the TiNiFe alloys, which affected the mechanical properties. Increasing the content of Ni had little influence on the grain size of TiNiFe alloys. With the replacement of Ni by Fe, the lattice constant of TiNiFe alloys decreased as the Ni content increased. |
