Sn effect on microstructure and mechanical properties of ultrafine eutectic Ti-Fe-Sn alloys

摘要

Microstructural investigations on ultrafine eutectic (Ti_(65)Fe_(35))_(100-x)Sn_ alloys with x= 0,1 and 3 at. percent reveal that additional Sn is effective to control formation of the micron-scale dendrites and to decrease the length-scale of lamellar spacing with enhancing macroscopic plasticity at room temperature compression. Hence, it is possible to understand the influence of the microstructural change on the plasticity of the ultrafine eutectic Ti-Fe-Sn alloys.
