Claims (2)

1. Способ повышения циклической прочности деталей машин преимущественно из жаропрочных сплавов, включающий нагрев до температуры начала термопластических деформаций с последующим охлаждением, отличающийся тем, что создают больше градиенты температур на поверхности путем интенсивного охлаждения нагретых деталей жидкостью под давлением, причем температура нагрева детали значительно ниже фазовых переходов и структурных изменений.1. A method of increasing the cyclic strength of machine parts primarily from heat-resistant alloys, including heating to the temperature of the onset of thermoplastic deformation followed by cooling, characterized in that they create more temperature gradients on the surface by intensive cooling of the heated parts with liquid under pressure, and the temperature of the part is much lower than phase transitions and structural changes. 2. Способ по п.1, отличающийся тем, что для достижения эффекта охлаждение производят под давлением 5 - 6 атм. 2. The method according to claim 1, characterized in that in order to achieve the effect, cooling is performed under a pressure of 5-6 atm.
