Abstract
Ti alloys are difficult to machine, accounting for 50-75% of the final component price, necessitating urgent improvements in machinability to increase their demand in several fields. This study found that adding small amounts of Ce (0.1-2.0wt.%) significantly improves the machinability of Ti-6Al-4V alloy. Here, we systematically analyzed microstructural changes due..... More

Abstract
This study demonstrates that the addition of the rare earth element Erbium (Er) significantly enhances the machinability and tensile properties of titanium (Ti). Pure Ti alloys and Er-added Ti alloys with 0.5-1.1 wt.% Er content were prepared, and their microstructure, machinability, and tensile properties were compared. Two different types of..... More

Abstract
Fe-Mn-Si based shape memory alloy is a new functional material that can be used to apply prestress to civil and structural components such as concrete structures. In this study, the effects of alloying elements Ni, C and Ti on the mechanical and shape memory properties of the alloy were investigated..... More
