Обсуждаются критерии оптимизации режимов ударно-волновой обработки для повышения усталостного ресурса сплавов авиационного моторостроения, основанные на учете автомодельности пластических волновых фронтов и кинетики роста усталостных трещин. Показано, что закономерности автомодельности, отраженные в степенных зависимостях структурированных волновых фронтов при амплитудах ударного импульса 1–10 ГПа и скоростях деформации 10[5]–10[6] с[-1], соответствуют «инвариантам действия», определяющим диссипативные свойства (stored energy) материалов, обусловленные многомасштабным развитием дефектов. Показана связь волновых «инвариантов действия» с инвариантными параметрами, характеризующими степенную кинетику развития усталостных трещин. Исследована связь структурных масштабов материала с «инвариантами действия». Количественный трактофафический анализ с использованием данных интерферометрии поверхностей разрушения позволил идентификацию структурных масштабов для определения «инвариантов действия», определяющих кинетику развития усталостных трещин в материалах после удара-волновой обработки. Развиты методические основы исследования поведения материалов при последовательных ударно-волновых и усталостных воздействиях, позволяющие оптимизацию процессов ударно-волновой проковки (LSP – Laser Shock Peening) для обеспечения максимального усталостного ресурса. Применительно к LSP-обработкам материалов авиационного моторостроения показана необходимость реализации полного исследовательского цикла, включающего: – проведение эксперимента для преломовного нагружения для получения стандартных образцов с параметрами нагружения, прогнозируемыми для режимов LSP; – проведение стандартных усталостных испытаний на образцах, подвергнутых ударно-волновому нагружению, в сочетании с методами структурного анализа; – обоснование моделей, описывающих структурированные волновые фронты, для исследования LSP воздействия и кинетики развития усталостных трещин с последующим изучением влияния этого воздействия на усталостные свойства на основе прогнозируемых режимов LSP по данным модельных экспериментов, результатов структурного анализа; использование «инвариантов действия» в качестве параметров оптимизации режимов LSP.

Self-similar patterns of structure formation and assessment of the resource of aviation engine alloys under consecutive shock wave and fatigue loads

The criteria for optimizing shock-wave treatment modes to increase the fatigue life of aircraft engine alloys are discussed. They are based on taking into account the self-similarity of plastic wave fronts and the kinetics of fatigue cracks. It is shown that the self-similarity patterns reflected in the power dependence of structured wave fronts at shock pulse amplitudes of 1-10 GPa and strain rates of 10^10^ s^1 correspond to the "action invariants" that determine the dissipative properties (stored energy) of materials caused by multiscale defect development. The relationship between wave "action invariants" and invariant parameters characterizing the power law of fatigue crack kinetics is shown. The relationship between the structural scales of the material and the "action invariants" is investigated. Quantitative fractographic analysis using fracture surface interferometry data allowed the identification of structural scales for determining the "action invariants" that determine the kinetics of fatigue crack development in materials after shock-wave treatment. Methodological principles for studying the behavior of materials under successive shock-wave and fatigue effects have been developed, allowing the optimization of Laser Shock Peening (LSP) processes to ensure maximum fatigue life. With regard to LSP treatments of aircraft engine materials, the need for a full research cycle has been shown, including: – conducting experiments on plane-wave loading to obtain standard samples with loading parameters predicted for LSP modes; – conducting standard fatigue tests on samples subjected to shock-wave loading, in combination with structural analysis methods; – substantiation of models describing structured wave fronts for the study of LSP impact and the kinetics of fatigue crack development with subsequent study of the influence of this impact on fatigue properties based on predicted LSP modes according to model experiments and results of structural analysis; use of "action invariants" as parameters for optimizing LSP modes.
