This paper reviews the methods of strengthening molybdenum alloys with metal oxides and carbides and their effects on alloy structure and properties, providing guidance for the design of high-performance refractory molybdenum alloys.
Metal oxide and carbide strengthening molybdenum (Mo) alloys have been designed as promising ad-vanced materials in refractory metals to solve some of the core engineering problems in superalloy ap-plications. Hence, there is a need to summarize the results obtained and evaluate the opportunities for preparing high-performance Mo alloys by strengthening metal oxides and carbides to improve the per-formance characteristics of Mo metal materials. This paper reviews the results of the reported work con-cerning the structure and properties of Mo alloys with different metal oxide and carbide strengthening methods added to Mo matrix. The influence of the doping of La2O3 and Y2O3 particles, ceramic Al2O3 and ZrO2 particles, and refractory TiC and ZrC carbides particles of Mo alloys are discussed. The impacts of particle morphology, size, distribution and volume fractions of oxide and carbide are analyzed, as well as the specific features of different doping techniques for obtaining high-performance Mo alloys mate-rials. This work will guide future research on the design of high-performance refractory Mo alloys by adding oxides and carbide particles, helping to solve the core issues in the field of superalloy application research.& COPY; 2023 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science & Technology.
