It has been found that the heating of the model cell is largely determined by the level of absorbed microwave power than by the time of exposure to the electromagnetic field. This effect is more pronounced at high power levels. The temperature distribution along the radius of the model cell is uneven, expressed in a higher heating intensity in the central region adjacent to the rod. Towards the periphery, the temperature decreases according to a law close to exponential. At a power of 30–38 μW, the difference in temperature of the specified regions reaches 30–35°C, and the effect of time is reflected in an increase in temperature by no more than 4–6%. In the studied range of microwave radiation powers, the temperature in the carbon rod region increases by 82.8%, and at the periphery, the temperature increases by 23.2%.

This theory predicts the behavior of materials exposed to small and large deformations. Owing to the rubber-like properties (e.g., the ability to withstand gigantic deformations returning to the original state or close to it when the load is lifted), hyperelastic materials are widely applied in modern science and technology. Study of the properties of hyperelastic materials is exceptionally important for medical materials science since all soft tissues of human and animal bodies are considered hyperelastic. The energy approach is very important and informative to explore deformation properties in these materials. We calculate the energy W of deformable hyperelastic incompressible bodies under tension using an example of aortic valve biomaterial. We make use of the most common hyperelastic models: the neo-Hookean model, the Mooney-Rivlin (two-parameter) model, the Ogden (first order) model, the polynomial (second order) model, the Yeoh (third order) model, and the Veronda–Westmann model. The statistical indicators of the value of W obtained are analyzed for all models. The mean value of W is 0.377 ± 0.03 J/cm3 (M ± SD), the coefficient of variation being CV = 7.45%. It is established that the average relative deviation of W from the average value for other (linear, bilinear, and exponential) deformation models is 10.08%, which is almost two times higher than that of hyperelastic models (p < 0.05).","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"16 4","pages":"1131 - 1134"},"PeriodicalIF":0.3,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160594","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}

Silicide formation during mechanical activation begins already after 9 min of milling, and only the highest silicide CrSi2 is observed up to 60 min. During the milling, a roll-shaped structure is formed from alternating layers of Cr and Si, which become thinner with increasing activation time, reaching the diffusion path lengths of each other’s components in some places. With subsequent rapid (~6°C/s) heating of the activated mixtures to a temperature of 1000°C, starting from a milling time of 45 min, a state close to phase equilibrium is established, in which the content of CrSi2 is maximal, but CrSi, Cr5Si3, and Si are also present (up to 10% in total). The diffusion nature of silicide formation is confirmed both during mechanical synthesis and during subsequent rapid heating. In this case, the observation of only one highest silicide CrSi2 during milling is probably due to the abnormally large coefficient of interdiffusion of components in this silicide at low temperatures compared to other silicides, the layers of which in the “diffusion pie” are significantly thinner and are not detected in X-ray diffraction analysis.</div>","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"16 4","pages":"1022 - 1029"},"PeriodicalIF":0.3,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160906","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}
