В работе представлены результаты исследования влияния вариации фазового состава композитных (1−x)Si3N4 – xAl2O3 керамик на сохранение устойчивости прочностных свойств в случае облучения тяжелыми ионами Xe23+ (230 МэВ) при флюенсах 1011–1014 ион/см2 . Вариация концентрации компонент была выбрана с учетом возможности получения композитных керамик с различным соотношением фаз: Si3N4, Al2O3,а также Al2(SiO4)O и SiO2, формирование которых в составе керамик связано с процессами термического разложения Si3N4 при высокотемпературном отжиге в кислородосодержащей атмосфере и фазовых трансформаций по типу формирования твердых растворов. Выбор типа ионов для облучения обусловлен возможностями моделирования процессов структурных повреждений, приводящих к разупрочнению поврежденного слоя, сравнимых с воздействием осколков деления ядерного топлива в керамиках – материалах инертных матриц дисперсного ядерного топлива. В ходе проведенных исследований, установлено, что при флюенсах облучения 1011– 1012 ион/см2 структурные изменения, связанные с формированием одиночных изолированных структурнодеформированных включений не приводит к существенным изменениям прочностных характеристик керамик, при этом малые изменения наблюдаемые связаны с деформационными искажениями, накопление которых приводит к дестабилизации поврежденного слоя. В случае более высоких флюенсов облучения (выше 1012 ион/см2 ) для которых характерно формирование эффектов перекрытия дефектных областей в поврежденном слое, наибольшей устойчивостью к разупрочнению обладают керамики 0,4 Si3N4 – 0,6 Al2O3, в которых согласно данным рентгенофазового анализа доминирующей фазой является Al2(SiO4)O, наличие которой обуславливает большое количество границ зерен, что в свою очередь приводит к дислокационному упрочнению и сдерживанию процессов разупрочнения, связанного с деформационными искажениями поврежденного слоя.

The paper presents the results of investigation of the influence of the variation of the phase composition of composite (1−x)Si3N4 – xAl2O3 ceramics on the stability of strength properties in the case of irradiation with heavy ions Xe23+ (230 MeV) at fluences1011–1014 ions/cm2 . The variation of the component concentration was chosen taking into account the possibility of obtaining composite ceramics with different phase ratio: Si3N4, Al2O3, as well as Al2(SiO4)O and SiO2, the formation of which in the composition of ceramics is associated with the processes of thermal decomposition of Si3N4 during high-temperature annealing in an oxygen-containing atmosphere and phase transformations by the type of solid solution formation. The choice of the type of ions for irradiation is conditioned by the possibilities of simulation of structural damage processes leading to unstrengthening of the damaged layer, comparable to the impact of nuclear fuel fission fragments in ceramics – materials of inert matrices of dispersed nuclear fuel. In the course of the conducted studies, it was established that at irradiation fluences of 1011–1012 ion/cm2 structural changes associated with the formation of single isolated structurally deformed inclusions do not lead to significant changes in the strength characteristics of ceramics, while small changes observed are associated with deformation distortions, the accumulation of which leads to destabilization of the damaged layer. In the case of higher irradiation fluences (above1012 ions/cm2 ), which are characterized by the formation of the effects of overlapping defect regions in the damaged layer, the ceramics of 0,4 Si3N4 – 0,6 Al2O3, in which, according to X-ray phase analysis data, the dominant phase is Al2(SiO4)O, the presence of which causes a large number of grain boundaries, which in turn leads to dislocation hardening and restraint of the disordering processes associated with deformation distortions of the damaged layer.
