Research on Preparation and Properties of Al2O3-doped Molybdenum Wire AITranslate
Abstract AITranslate
In order to improve the properties of molybdenum wire,using ammonium tetramolybdate,nitric acid,aluminum nitrate and urea as raw materials,MoO3-Al2O3 precursor was prepared by hydrothermal method,and then Mo-Al2O3 composite powder was obtained by low temperature calcination and two-stage hydrogen reduction.Then,the Mo-Al2O3 molybdenum rod with a diameter of about 20mm was obtained by pressing and high temperature sintering,and finally the Mo-Al2O3 molybdenum wire with a diameter of 0.18mm was obtained by blanking,rotary forging,drawing,annealing and cold drawing.The effects of different Al2O3 doping contents on the microstructure and properties of molybdenum powder and molybde-num wire were studied,and the strengthening mechanism of molybdenum wire was analyzed.The results show that the addition of Al2O3 particles can refine Mo grains and improve the properties of molybdenum wire.The more the addition amount of Al2O3 particles,the greater the grain refinement degree of Mo-Al2O3,and the better the mechanical properties of molybdenum wire.The strengthening mechanism of Al2O3-doped molybdenum wire is dispersion strengthening,grain refinement strengthening,work harden-ing and texture strengthening,which together endow the Al2O3-doped molybdenum wire with ultra-high strength.Within the experimental range,the tensile strength and elongation of Mo-0.25%Al2O3are the highest,reaching 2243MPa and 3.9%,respectively.
