Fa'idodin Waya Molybdenum Doped Tare da Lanthanum

Kwatanta yanayin zafi na sake sakewa: A bayyane yake an faɗaɗa ƙananan ƙirar waya na molybdenum a 900 ℃ kuma an sake yin recrystallized a 1000 ℃. Tare da haɓakar zafin jiki na annealing, ƙwayar recrystallization shima yana ƙaruwa, kuma kyallen takarda suna raguwa sosai. Lokacin da zafin zafin jiki ya kai 1200 ℃, wayar molybdenum an sake dawo da ita gaba ɗaya, kuma microstructure ɗinta yana nuna nau'in nau'in nau'in nau'in nau'in recrystallized. Yayin da zafin jiki ya ƙaru, hatsin yana girma ba daidai ba kuma yana bayyana ƙananan hatsi. Lokacin da aka rufe a 1500 ℃, wayar molybdenum tana da sauƙin karye, kuma tsarinta yana nuna nau'in hatsi mai ƙima. Tsarin fiber na lanthanum-doped molybdenum waya ya faɗaɗa bayan an cire shi a 1300 ℃, kuma siffa mai kama da haƙori ya bayyana a iyakar fiber. A 1400 ℃, da recrystalized hatsi bayyana. A 1500 ℃, fiber texture ya ragu sosai, kuma tsarin recrystallized ya bayyana a fili, kuma hatsi ya girma ba daidai ba. Matsakaicin recrystallization na lanthanum-doped molybdenum waya ya fi na tsantsar waya molybdenum, wanda ya faru ne saboda tasirin La2O3 na kashi na biyu. Mataki na biyu na La2O3 yana hana ƙauran iyakar hatsi da haɓakar hatsi, don haka ƙara yawan zafin jiki na recrystallization.

Kwatanta Kayan Aikin Injiniyan Daki: Tsaftataccen wayan molybdenum mai tsafta yana ƙaruwa tare da ƙara yawan zafin jiki. Lokacin da zafin jiki na anneal a 1200 ℃, elongation ya kai matsakaicin darajar. A elongation rage tare da anneal zafin jiki karuwa. Annealed a 1500 ℃, kuma elongation ya kusan daidai da sifili. The elongation na La-doped molybdenum waya yayi kama da tsarki molybdenum waya, da kuma elongation kudi kai matsakaicin lokacin da annealed a 1200 ℃. Sa'an nan kuma elongation yana raguwa tare da yawan zafin jiki. Bambancin kawai shine raguwar raguwa yana jinkirin. Ko da yake elongation na lanthanum-doped molybdenum waya yana jinkiri bayan annealing a 1200 ℃, elongation ya fi na molybdenum waya zalla.
