In the study, we applied the nonlinear ultrasonic for evaluation the creep damage and the microstructural degradation in γ”for Inconel 718 plates. The nonlinear ultrasonic holds the potential of becoming the primary means of characterizing creep in metals, because it can probe the change of dislocation structure during the creep. Its sensitivity to microstructural evolutions during the creep is often higher than that of linear properties. We elucidated the relationship between microstructural change and the evolutions of nonlinear acoustic characterizations three-wave- interacting, with electromagnetic acoustic resonance (EMAR) throughout the creep lifetime, nonlinearly was relationship change in dislocation density.

Исходными компонентами являлисьоксиды кобальта Со3О4, цинка ZnO, алюминия Al2O3 и шестиводный нитрат магния Mg(NO3)2∙6H2O. B качестве металла-восстановителя использовался порошок алюминия промышленной марки АСД-4. Применение механохимической активации шихты существенно влияет на параметры горения системы. Исследованы фазовый состав и структура продуктов синтеза до и после механохимической активации. Состав продуктов подтвержден рентгенофазовым анализом (дифрактометре «ДРОН-2М», фильтрованное Сo kα-излучение). ИК-спектроскопический анализ (ИК-Фурье спектрометр Nicolet 5700) показал, что в процессе механохимической активации шихты происходит выделение воды из шестиводного нитрата магния, о чем свидетельствуют полосы поглощения, относящиеся к свободной воде, наблюдается фазовый переход γ-Al2O3→α-Al2O3, образуются зародыши новой фазы (шпинели). Морфологические особенности поверхности частиц исходной смеси изучены с применением растровой электронной микроскопии (Philips SEM 515). Микроструктуры продуктов синтеза с применением механохимической активации и без нее исследованы с помощью оптической микроскопии (Axiovert 200M).

The usual trigger circuit inside LTD cavity is a single wire O-ring and the minimum number of the external trigger cables connected to this O-ring is determined as 1 cable per 10 switches. In recent article LTD cavity of 34 bricks with novel trigger system and special internal trigger brick was represented. In our tests similar trigger system was used but without the internal trigger brick. The LTD cavity of 16 bricks was tested in more than 3000 shots. In all these shots no malfunction was observed. Numerical simulation has shown that up to 40 switches might be successfully triggered by 1 external trigger cable by using both the novel trigger system and a simple wire O-ring. This last prediction was tested in experiment with LTD cavity of 16 bricks in 600 shots and no malfunction was observed also. The results of this research have shown that previous requirement can be reduced to less strict claim of 1 trigger cable per 16 switches.","PeriodicalId":156877,"journal":{"name":"8th International Congress on Energy Fluxes and Radiation Effects","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126656857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advantage of radiosurgery is non-invasiveness, the effectiveness of exposure to foci and the low probability of radiation reactions after treatment. However, in patients with a tumor volume exceeding 3 centimeters in diameter, with radiosurgical doses (>18 Gy), the risk of post-radiation complications is subsequently high, therefore radiosurgical methods of hypofractionation and staged radiosurgery are increasingly used. The research included a group of patients (46 people) who underwent treatment by the method of staged radiosurgery and a group of patients (27 people) who underwent hypofractionation. The clinical study was conducted at the Leksell Gamma Knife Icon installation (Stockholm, Sweden). The summed dose was in the range from 16 to 30 Gy.
