첨가원소 Sn의 증가에 따른 Ti-Fe-Sn 극미세 합금의 미세조직 및 기계적 성질 변화 |
초록 |
In the present study, microstructural evolution and mechanical properties of Ti-Fe-Sn ultrafine eutectic alloys have been investigated. Ultrafine eutectic microstructure consisting of a mixture of β-Ti solid solution and FeTi intermetallic compound homogeneously formed in Ti70.5 Fe29.5, Ti69.8Fe29.8Sn1 and Ti68.4Fe28.6Sn3 alloys. Addition of Sn in the Ti70.5Fe29.5 eutectic alloy induced volume fraction change of FeTi phase. In addition lattice parameter of β-Ti phase changed due to increasing Sn content. Addition of Sn 3 at.% induced morphology change of the eutectic colony into spherical shape and decreasing of colony size. Refining of microstructure reveal that development of mechanical properties, With increasing the content of Sn in these alloys, it is effective to enhance the macroscopic plasticity up to 4.7 %. |
