1. Способ обработки монокристаллических турбинных лопаток из никелевых сплавов, включающий нагрев, отличающийся тем, что, с целью повышения усталостной прочности, перед нагревом проводят поверхностную пластическую деформацию со степенью 5-25%, а нагрев ведут до 1200-1250°С с выдержкой 10-60 мин при этой температуре.2. Способ по п.1, отличающийся тем, что после нагрева осуществляют дополнительную поверхностную пластическую деформацию со степенью 1-3%.1. The method of processing single-crystal turbine blades of nickel alloys, including heating, characterized in that, in order to increase fatigue strength, surface plastic deformation is carried out with a degree of 5-25% before heating, and heating is carried out to 1200-1250 ° C with a holding 10 -60 min at this temperature. The method according to claim 1, characterized in that after heating, an additional surface plastic deformation is performed with a degree of 1-3%.
