Abstract

Было обнаружено, что электрошлаковый переплав металлического титана или его сплавов при регулируемых парциальных давлениях азота и до некоторой степени кислорода может растворять богатые азотом включения, способствуя устранению или уменьшению центров порождения трещин. Способ электрошлакового переплава титана и его сплавов обеспечивает растворение или, по меньшей мере, уменьшение богатых азотом включений во время процесса плавления.Международная заявка была опубликована вместе с отчетом о международном поиске.It was found that electroslag remelting of metallic titanium or its alloys under controlled partial pressures of nitrogen and to some extent oxygen can dissolve nitrogen-rich inclusions, helping to eliminate or reduce the centers of production of cracks. The method of electroslag remelting of titanium and its alloys provides for the dissolution or at least the reduction of nitrogen-rich inclusions during the melting process. The international application was published along with an international search report.
