钼钒铝三元中间合金的制备及组织性能研究
Preparation and Study of the Microstructure and Properties of Molybdenum Vanadium Aluminium Ternary Intermediate Alloy
摘要
Abstract
To obtain ternary intermediate alloys of vanadium,molybdenum and aluminium with high actual yields,controllable processes and low carbon contents,Mo35-V45-Al20,Mo40-V40-Al20 and Mo45-V35-Al20 alloys were prepared through aluminothermic reactions and process control.The differences in the microstructures and properties of different alloys were also explored,laying a foundation for the production of high-quality ternary intermediate alloys of molybdenum,vanadium and aluminium.The results reveal that the elemental contents of the Mo35-V45-Al20,Mo40-V40-Al20,and Mo45-V35-Al20 alloys prepared via the heating process meet the industry standards and that the main phase of the three alloys is the V0.5Mo0.5 phase.A small endothermic peak appears in the Mo40-V40-Al20 alloy at 1 370.4 ℃,which is likely the peak corresponding to the initiation of melting of the V0.5Mo0.5 phase.With increasing Mo content,the number of V0.5Mo0.5 second phase particles in the alloy increases,and the second phase particles in the Mo40-V40-Al20 alloy are finer and more evenly distributed.Moreover,the alloy density significantly increases.The maximum hardness of the Mo40-V40-Al20 alloy is 71.24 HRC.关键词
