FIELD: machine engineering, possibly designing of units whose parts are subjected at operation to action of unstable or cyclic loads.
SUBSTANCE: method comprises steps of placing between surfaces of part interlayer of plastic material at relation of limit strength of interlayer material to that of material of each part no more than 0.6. It is possible to use flat washer of stainless steel with volume porosity 25 - 40% or metallic gauze interlayer that may be fixed by means welding or soldering. At joining turbine blade with impeller disc washer is placed between working surfaces of tooth of blade member and disc tooth and it is fixed on one of working surfaces.
EFFECT: enhanced operational reliability of loaded parts due to redistribution of local stresses caused by inaccuracy of manufacturing process.
