Research on Preparation of Mo-Re Pre-Alloyed Powder by Sol-Gel Method AITranslate
Abstract AITranslate
Mo-47.5Re pre-alloyed powder was prepared by wet chemical sol-gel method with ammonium heptamolybdate tetrahydrate,ammonium perrhenate and anhydrous oxalic acid as raw materials.The ther-mal decomposition and material change rule of wet gel of molybdenum-rhenium precursor during drying-calcination process were studied.Molybdenum-rhenium pre-alloyed powder containing molybdenum matrix phase with solid solution rhenium and molybdenum-rhenium intermediate phase(σ-phase andχ-phase)was prepared.The particles of the pre-alloyed powder are fine,the laser particle size D50 is about 5.09μm,and the distribution of molybdenum and rhenium elements is uniform and highly dispersed.Therefore,it is an ideal powder metallurgy raw material for preparation of molybdenum-rhenium alloy with high rhenium content.
