Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations
Current state-of-the-art metallic materials, such as Ni-based superalloys, are approaching the physical limits of their development, as the operating temperatures required for future applications are close to or beyond their melting points
The remarkable properties of some of these alloys make them promising candidates for use in a wide range of current and future applications. These advanced materials are based on 13 refractory metals, W, Re, Os, Ta, Mo, Nb, Ir, Ru, Hf, Rh, V, Cr, and Zr, whose melting points are between 1855 ◦C (Zr) and 3422 ◦C (W)

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Current state-of-the-art metallic materials, such as Ni-based superalloys, are approaching the physical limits of their development, as the operating temperatures required for future applications are close to or beyond their melting points. Progress in high social-impact fields, such as energy and transportation, requires the exploration and development of new material solutions with improved structural or functional properties at much higher temperatures.
