Abstract
Herein, structure, mechanical properties, and oxidation behaviour of a refractory (CrHfMoNbTaTiVZr)84Si16 complex concentrated alloy (RCCA) prepared by vacuum arc melting were studied. Consisting of C11b-MeSi2, C14 Laves, bcc, and Me5Si3 phases, the alloy exhibited better 1200 °C-specific yield strength (45 MPa cm3 g−1), fracture toughness (5.77 ± 1.58 MPa m1/2), and 1 h-mass gain at 1200 °C (∼60 mg cm−2) than most of current RCCAs.
期刊介绍：
The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
