Information × Registration Number 0214U007027, 0112U002790 , R & D reports Title Physical-chemical bases of increasing cyclic and static durability of products made of titanium alloys with surface layers gradient hardening of the (O, N, C) interstitial elements' by thermal diffusion saturation popup.stage_title Head Fedirko Viktor, Registration Date 02-04-2014 Organization Karpenko Physico-Mechanical Institute of the National Academy of Science of Ukraine popup.description2 It is shown that the enhancement of the surface layer of thermo-diffusion saturation of oxygen- controlled environment increases the fracture resistance of titanium alloys VT1-0, PT-7M and OT4-1 for cyclic and static loads and long depends on the level of strengthening (K) and the depth of hardened zone (l). Dependence is extreme character with a maximum at an 'optimal' of interstitial solid solution strengthening (Kopt. and lopt .). First time the universal increase in fatigue durability of titanium alloy samples for oxygen saturation, not only but also implementing other impurities (N , C) in certain ratios K and l. Experimentally reproducible effect of increasing the durability of titanium alloy VT1- 0, PT-7M , OT4 -1 with reinforced oxygen at "optimal " levels (Kopt.) surface layer under different loading conditions: for pure bending, by rotating bending; under cyclic tension and prolonged static load on the basis of 1000 hours.
