Description
лорода при этих температурах равна мм рт. ст.The temperature at these temperatures is mm Hg. Art.
Предлагаемый способ позвол ет дл сплавов на основе молибдена/ легированных углеродом и одним из элементов IV А группы Периодической системы, достичь равномерного раснределени частиц окислов на издели х существенно большей толщины, чем при обычном методе.The proposed method allows for alloys based on molybdenum / doped with carbon and one of the elements of Group IV A of the Periodic System, to achieve uniform distribution of oxide particles on products of substantially greater thickness than with the conventional method.
При осуществлении предлагаемого способа на сплаве состава, ат.%: Mo+0,2Zr+ +0,2C+0,lNi, в виде нагартованного листа толщиной 1 мм подвергаемого отжигу при 1400°С в вакууме в течение двух часов до образовани карбидов циркони , в результате последующего окислительного отжига ири 1800°С в вакууме Ю мм рт. ст. по всей глубине листа наблюдаетс равномерное но глубине распределение частиц ZrOo, повтор ющее распределение исходных карбидов .When implementing the proposed method on an alloy of composition, at.%: Mo + 0.2Zr + + 0.2C + 0, lNi, in the form of a 1 mm thick hard-faced sheet subjected to annealing at 1400 ° C in vacuum for two hours to form zirconium carbides, as a result of subsequent oxidative annealing iri 1800 ° C in vacuum Yu mm RT. Art. over the entire depth of the sheet, a uniform but deep distribution of ZrOo particles is observed, repeating the distribution of the initial carbides.
Така же картина наблюдаетс и при образовании карбидов циркони путем высокотемпературной прокатки с промежуточными отжигами при 1300°С силава состава: Mo-f 0,8%Zr+0,8%C, внутреннее окислениеThe same picture is observed in the formation of zirconium carbides by high-temperature rolling with intermediate annealing at 1300 ° C. The strength of the composition: Mo-f 0.8% Zr + 0.8% C, internal oxidation
которого происходит в процессе отжига при 1700°С в течение двух часов в атмосфере водорода.which occurs in the process of annealing at 1700 ° C for two hours in an atmosphere of hydrogen.
