ʻOi aku ka kiʻekiʻe o ka mahana recrystallization o ka uea molybdenum lanthanum-doped ma mua o ka uea molybdenum maʻemaʻe, a no ka mea hiki ke hoʻomaikaʻi ka liʻiliʻi o La2O3 i nā waiwai a me ke ʻano o ka uea molybdenum.Ma waho aʻe, hiki i ka La2O3 ke hoʻonui i ka ikaika o ka wela o ka lumi o ka uea molybdenum a hoʻomaikaʻi i ka brittleness o ka lumi ma hope o ka recrystallization.
Hoʻohālikelike ʻia ʻo Recrystallization: Ua hoʻonui ʻia ka microstructure o ka uea molybdenum maʻemaʻe ma 900 ℃ a hoʻihoʻi hou ʻia ma 1000 ℃.Me ka piʻi ʻana o ka mahana o ka annealing, hoʻonui pū ʻia nā kīʻaha recrystallization, a hoʻemi nui nā ʻiʻo fibrous.Ke piʻi ka mahana annealing i 1200 ℃, ua hoʻihoʻi hou ʻia ka uea molybdenum, a ʻo kāna microstructure e hōʻike ana i kahi ʻano like like equiaxed recrystallized palaoa.I ka piʻi ʻana o ka mahana, ulu ʻole ka ʻai a ʻike ʻia nā ʻano huaʻai.Ke hoʻopili ʻia ma 1500 ℃, ua maʻalahi ka uhai ʻana o ka uea molybdenum, a hōʻike kona ʻano i ka palaoa equiaxed coarse.Hoʻonui ʻia ke ʻano o ka fiber o ka lanthanum-doped molybdenum wire ma hope o ka hoʻopili ʻia ʻana ma 1300 ℃, a ʻike ʻia ke ʻano like me ka niho ma ka palena o ka fiber.I ka 1400 ℃, ua ʻike ʻia nā ʻōpala i hoʻoponopono hou ʻia.Ma ka 1500 ℃, ua emi loa ka ʻano o ka fiber, a ua ʻike maopopo ʻia ke ʻano o ka recrystallized, a ua ulu like ʻole nā hua.ʻOi aku ka kiʻekiʻe o ka mahana recrystallization o ka uea molybdenum lanthanum-doped ma mua o ka uea molybdenum maʻemaʻe, ʻo ia ka mea nui ma muli o ka hopena o nā ʻāpana lua o La2O3.ʻO ka La2O3 ka lua o ka hana keʻakeʻa i ka neʻe ʻana o ka palena o ka palaoa a me ka ulu ʻana o ka palaoa, pēlā e hoʻonui ai i ka mahana recrystallization.
Hoʻohālikelike Nā Pono Mechanical lumi lumi: Ke hoʻonui nei ka elongation o ka uea molybdenum maʻemaʻe me ka piʻi ʻana o ka mahana annealing.I ka manawa o ka anneal wela ma 1200 ℃, hiki i ka elongation ke kiʻekiʻe loa.Ke emi nei ka elongation me ka piʻi ʻana o ka mahana anneal.Hoʻopili ʻia ma 1500 ℃, a ua aneane like kona elongation me ka ʻole.ʻO ka elongation o La-doped molybdenum uea like me ka molybdenum uea maʻemaʻe, a hiki i ka elongation rate ke kiʻekiʻe loa i ka wā i hoʻopili ʻia ma 1200 ℃.A laila emi ka elongation me ka piʻi ʻana o ka mahana.ʻO ka mea ʻokoʻa wale nō ka lohi o ka emi ʻana.ʻOiai ua lohi ka elongation o ka uea molybdenum lanthanum-doped ma hope o ka annealing ma 1200 ℃, ʻoi aku ka kiʻekiʻe o ka elongation ma mua o ka uea molybdenum maʻemaʻe.
