Изобретение относитс  IK области порошковой металлургии, в частности, к способам изготовлени  спеченных изделий на основе тугоплавких материалов.The invention relates to the IC field of powder metallurgy, in particular, to methods for manufacturing sintered articles based on refractory materials.

Известен способ изготовлени  спеченных изделий из карбида гафни , в ключаюидий гор чее прессование порошка карбида гафии .A known method for the manufacture of sintered products of hafnium carbide, in a key, is hot pressing of gafium carbide powder.

С целью повышени  пластичности порошка карбида гафни  при обработке давлением и упрощени  технологии изготовлени  комнактных изделий перед гор чим прессованием в порошок ввод т 3-25 вес. % карбида ванади , после гор чего прессовани  провод т дополнительную обработку давлением, а затем карбид ванади  удал ют из изделий термообработкой при 2600-2800°С.In order to increase the plasticity of the powder of hafnium carbide during pressure treatment and to simplify the technology of manufacturing joint products, 3-25 wt.% Are introduced into the powder before hot pressing. % of vanadium carbide, after hot pressing, additional pressure treatment is carried out, and then vanadium carbide is removed from the products by heat treatment at 2600-2800 ° C.

Способ осуществл етс  следующим образом .The method is carried out as follows.

Подготовленную иеремешиванием смесь порошков карбидов с размером частиц 2-5 м«, состо щую из 96 вес. % карбида гафни  и 4 вес. % карбида ванади , прессуют в заготовку при давлении 300 кг/см и температуре 2300°С.A mixture of carbide powders with a particle size of 2–5 m prepared by stirring, consisting of 96 wt. % hafnium carbide and 4 wt. % vanadium carbide, pressed into the workpiece at a pressure of 300 kg / cm and a temperature of 2300 ° C.

Полученные заготовки подвергают обработке давлением, а затем провод т термообработку при 2700°С :В течение 2 час дл  удалени  карбида ванади .The resulting preforms are subjected to pressure treatment, and then heat treated at 2,700 ° C: For 2 hours to remove vanadium carbide.

Введение 3-25 вес. % карбида ванади  позвол ет иовысить пластичность прессуемого порошка и создает возможность дл  существенного снижени  параметров процесса гор чего прессовани , что в свою очередь позвол ет проводнть высокотемпературную обработку давлением при относительно невысоких давлени х (100-200 кг/см-) со скоростью деформации 20-50% в час при температуреIntroduction 3-25 weight. % vanadium carbide allows to increase the plasticity of the powder to be pressed and creates an opportunity to significantly reduce the parameters of the hot pressing process, which in turn allows high-temperature pressure treatment at relatively low pressures (100-200 kg / cm-) with a deformation rate of 20- 50% per hour at temperature

2300-2400°С, а за счет этого обеспечиваетс  упрощенпе технологии изготовлени  комиактных изделий из карбида гафни .2300-2400 ° C, and due to this, the manufacturing technology of hafnium carbide compact products is simplified.
