Description

,ествующне быстрорежущие стали на основе железа обычно легированы углеродом, ванадием, вольфрамом, хромом и кобальтом. Известш случаи легировани  доиолиительио бором, азотом и некоторыми другими элементами . Однако заметного повышени  стойкости это дополнительное легирование не давало.Iron-based high-speed steels are commonly alloyed with carbon, vanadium, tungsten, chromium and cobalt. There are known cases of doiolithio lification with boron, nitrogen, and some other elements. However, this additional doping did not significantly increase the durability.

Пред,: о енный сплав отличаетс  дополиительны .м комплексным легированием трем  элементами - бором, ниобием и азотом, причем иовыитение стойкости составл ет пор дка п ти раз.Previously, the alloy is different in addition to the complex doping of the three elements — boron, niobium, and nitrogen, and the increase in durability is about five times.

Сплав Полтавит 1 имеет следующий состав (в о/о): углерод 1,50-1,80; ванадий 5,5- 7,5; вольфрам 7,2-8,8; хром 3,8-4,2; кобальт 3,5-4,5; ниобий 1,1 -1,3; бор 0,2-0,3 н азот 0,3-0,4.Alloy Poltavit 1 has the following composition (in o / o): carbon 1.50-1.80; vanadium 5.5-7.5; tungsten 7.2-8.8; chromium 3.8-4.2; cobalt 3.5-4.5; niobium 1.1 -1.3; boron 0,2-0,3 n nitrogen 0,3-0,4.

Предложеииый сплав может подвергатьс  термообработке. После отжига твердость снлава снижаетс  до 33 HRc. После закалкиThe proposed alloy may be heat treated. After annealing, the hardness of the melt decreases to 33 HRc. After quenching

И двухкратного отнуска твердость повышаетс  до 66 единиц HRc за счет мартенситного иревращеии  н дисперспопиого твердени .And a double derailment hardness is increased to 66 HRc units due to martensitic and rotation and dispersion hardening.

Сплав Полтавит 1 может быть получен паплавкой существующими методами.Alloy Poltavit 1 can be obtained by flocking existing methods.
