Essay

Cyclic crack propagation resistance alloys. The thesis deals with determination of pecularities of fatigue crack propagation and formation of the threshold crack resistance in the aluminium alloy AlMg6 at the original state as well as after preliminary plastic stretch and stress deformation. The method of estimation of the effective threshold SIF range of the AlMg6 alloy was suggested. General diagrams of the preliminary plastic deformation effect on the threshold SIF range and the fatique crack growth rate which allow to perfect the technology of the material press treatment were built. The sphere of usage is technology of processing of materials by pressure, the further scientific researches.
