Abstract Scope |
There is a continuous requirement to develop materials with higher temperature capabilities, because employment of these materials to internal combustion engines could enable us to operate internal combustion engines at higher temperatures, which results in the reduction of CO2 generation. Refractory high entropy alloys (RHEAs) or refractory compositionally complex alloys (RCCAs) are candidates of the next generation high temperature structural materials due to their high melting temperatures and reasonably good mechanical properties. On the other hand, such materials should have protective properties against oxidation and hot corrosion, thereby their oxidation behabior should be systematically investigated. This study focuses on the RHEAs or RCCAs which consist of the combination of following elements : Nb, Ti, Ta, Cr, Mo, Al. The effects of alloy composition on their mass change kinetics, constitution of thermally grown oxides will be systematically investigated and discussed. |
