Abstract

1. Способ изготовления крепежных элементов из высокопрочных титановых сплавов, содержащих стержень с головкой и резьбовым концом, включающий изготовление заготовок, горячую высадку, термообработку, механическую обработку, упрочнение галтели головки и накатывание резьбы, отличающийся тем, что накатывание резьбы производят при нагретой заготовке в интервале температур 350°C-200°C ниже температуры начала полигонизации, происходящей в процессе возврата после термообработки.2. Способ изготовления крепежных элементов из высокопрочных титановых сплавов по п.1, отличающийся тем, что накатку резьбы выполняют при завершении операции старения на этапе охлаждения.1. A method of manufacturing fasteners of high-strength titanium alloys containing a rod with a head and a threaded end, including the manufacture of blanks, hot upsetting, heat treatment, machining, hardening of the fillet of the head and thread rolling, characterized in that the thread rolling is performed with a heated workpiece in the interval temperatures 350 ° C-200 ° C below the temperature of the onset of polygonization that occurs during the return process after heat treatment. 2. A method of manufacturing fasteners of high strength titanium alloys according to claim 1, characterized in that the thread rolling is performed at the end of the aging operation at the cooling stage.
