Description
Изобретение относитс к металлургии, а именно к высокопрочным стал м дл отливок с повышенными характеристиками коррозионной усталости.This invention relates to metallurgy, namely, high strength steels for castings with enhanced corrosion fatigue characteristics.
Цель изобретени - повышение хрупкой прочности и эксплуатационной стойкости ,The purpose of the invention is to increase the fragile strength and service resistance,
Сталь выплавл ют в индукционных печах при 1590-1620°С с присадкой кобальта, теллура и ферросплавов перед разливкой расплава в формы. Химический состав исследованных сталей представлен в табл. 1. Ферробор, церий, теллур, кальций или алюминий ввод т при выпуске стали в ковш.Steel is smelted in induction furnaces at 1590-1620 ° C with an additive of cobalt, tellurium and ferroalloys before pouring the melt into molds. The chemical composition of the investigated steels is presented in table. 1. Ferroboron, cerium, tellurium, calcium or aluminum is introduced at the steel production into the ladle.
Механические свойства, эксплуатационна и термическа стойкость исследованных сталей представлены в табл. 2. Хрупкую прочность оценивают после термоциклиро- вани до 1000°С в течение 100 смен.Mechanical properties, operational and thermal stability of the investigated steels are presented in Table. 2. The brittle strength is evaluated after thermal cycling to 1000 ° C for 100 shifts.
Коррозионную стойкость оценивали по склонности стали к межкристаллитной коррозии (МКК) по методу АН ГОСТ 6032-75 и пределу коррозионной усталости, а термическую стойкость определ ли по количествуCorrosion resistance was evaluated by the tendency of steel to intergranular corrosion (MCC) according to the method of AN GOST 6032-75 and the limit of corrosion fatigue, and thermal resistance was determined by the number
циклов нагрева до 100°С и охлаждени на спокойном воздухе до по влени трещины. Испытани на ударный изгиб проводили на образцах типа 11 по ГОСТ 9454-78. Значение работы удара составл ло не менее 10% от максимальной энергии удара примен емого ма тника.heating cycles to 100 ° C and cooling in calm air until a crack appears. Impact bending tests were performed on samples of type 11 according to GOST 9454-78. The value of the impact work was at least 10% of the maximum impact energy of the applied tandem.
Предлагаема литейна сталь может быть использована в издели х новой техники при изготовлении высоконагруженных деталей сложной конфигурации, обладающих специальными свойствами.The proposed cast steel can be used in products of new technology in the manufacture of highly loaded parts of complex configuration with special properties.
Свойства литейных сталей в отливках приведены после закалки с температуры 950-970°С в масло и отпуска в течение 4 ч при 270-290°С. Термическа стойкость линейных сталей определена на отливках втулок при термоциклировании по режиму 20-1000°С на стендах с нагревом ТВЧ и охлаждением воздушной струей до по влени трещины. Как видно из табл. 2, предложенна литейна сталь обладает более высокими показател ми хрупкой прочностиThe properties of cast steel in castings are given after quenching from a temperature of 950–970 ° C to oil and tempering for 4 hours at 270–290 ° C. The thermal resistance of linear steels is determined on the castings of bushings during thermal cycling according to the regime of 20–1000 ° C on stands with high-frequency heating and air-cooling until a crack appears. As can be seen from the table. 2, the proposed cast steel has a higher brittle strength.
