Pakhomova, N. Ryzhov] Conclusions: 1. The changes in the martensite substructure of the surface layer have a determining effect on the contact fatigue life of N22 and 25N20 alloys subjected to shot-impact treatment (SH). 2. An increase in the contact life of iron-nickel alloys is attained in a narrow range of SH regimes, which ensure alongside with strengthening and creation of high residual compressive stresses a more stable structure, being characterized by a lowered level of microdistortions and low mobility of dislocations. 3. It is recommended to combine the shot-impact treatment of iron-nickel alloys with subsequent low-temperature annealing at which martensite hardening takes place as a result of strain aging and reduction of microdistortions which facilitate increase of resistance to contact fatigue failure. 4. The structure of iron-nickel alloys is similar to the martensite structure of the carbonized layers of gears. This permits the assumption of a similar mechanism of the effect of SH on carbonized gears. The results of this investigation can be used in developing SH regimes for gears.
