Abstract
Properties of used constructional materials mainly define increasing of aviation product’s operational indicators. Fatigue failure resistance of metal materials, as well as other physicomechanical properties, substantially depends on structure. Laser heat treatment of details from steel 40ХН allows raise fatigue failure resistance at microhardness increasing of a blanket in thermal influence zone in 2…2,5 times. It’s possible to get lower probability of fatigue cracks origin while in service.
