| Abstract Scope |
Medium entropy alloys (MEAs) have gained attention for their excellent mechanical properties, such as high strength and relatively high ductility that could even outperform the well-established and commercially-use Ti-6Al-4V. In particular, the MEAs comprising elements of Al and Ti attract enormous attention due to their lightweight feature compared to well-developed CoCrNi MEAs. This study constructs the phase diagrams of Ti-Al-Cr-V by experiments, such that the ordered B2 phase can be clearly distinguished from the disordered BCC phase via synchrotron x-ray measurements. Alongside the phase diagram determination, the microstructural evaluation and structural transformation for MEAs were captured. By associating the metallographic information with physical properties, promising MEAs with enhanced mechanical properties and desired transport properties can be located via the phase diagram engineering. |
