Изобретение относитс к разработке снособа модифицировани молибдена и его снлавов .This invention relates to the development of a method for modifying molybdenum and its catalysts.
Известен способ модифицировани молибдена редкоземельпымп металлами.There is a method for modifying molybdenum with rare-earth metals.
Ио предлагаемому способу в расплав ввод т тонкодисиерсный порошок боридов тугоплавких металлов в количестве до 1%. Это способствует получению мелкозернистой структуры и улучшению технологических свойств молибдена и его сплавов.According to the proposed method, a thinning powder of borides of refractory metals is introduced into the melt in an amount of up to 1%. This contributes to obtaining a fine-grained structure and improving the technological properties of molybdenum and its alloys.
В опытно-промышленных услови х модифицировали молибден и его сплавы с титаном и цирконием введением в качестве модификатора тугоплавких соединений бора: пентаборида вольфрама и молибдена, диборида титапа , карбида бора. Плавку провод т в вакуумной печи с введением модификатора в количестве до 1 % в виде тонкодисперсного порошка пепосредственно с расходуемым электродом .In experimental-industrial conditions, molybdenum and its alloys with titanium and zirconium were modified by introducing as a modifier refractory boron compounds: tungsten and pentaboride molybdenum, titap diboride, boron carbide. Melting is carried out in a vacuum furnace with the introduction of a modifier in an amount of up to 1% in the form of fine powder directly with a consumable electrode.
Предмет изобретени Subject invention
Снособ модифицировани молибдена и его сплавов, отличающийс тем, что, с целью получени мелкозернистой структуры и улучшени технологических свойств, в расплав ввод т тонкодисперсный порошок боридов тугоплавких металлов в количестве до 1,0%.A method for modifying molybdenum and its alloys, characterized in that, in order to obtain a fine-grained structure and improve technological properties, fine-dispersed powder of borides of refractory metals in the amount of up to 1.0% is introduced into the melt.
