This pa.er dea.s with a.peculia. rheologica. beha.ior of a.uminum a. nea.-solidus tempera.ures.

Electron ba.ksca.ter diffra.tion a.a.ysis ha. shown tha. a. tempera.ures ra.ging between 540 a.d 640℃ a.d stra.n ra.es ra.ging from 0.06 to 0.1 s-1, the ma.n process of softening is dyna.ic polygoniza.ion, resulting in in situ recrysta.liza.ion. a. higher stra.n ra.es, ra.ging between 0.8 a.d 1.2 s-1, a.d tempera.ures ra.ging between 560 a.d 640℃, the recovery is dyna.ic. This unusua. beha.ior of the mecha.ism of softening a.d the presence of the inverse stra.n ra.e dependence of stra.n resista.ce ca. be expla.ned by blocking the motion of free disloca.ions by foreign a.oms, which occurs a. stra.n ra.es ra.ging between 0.06 a.d 0.1 s-1 This process results in disloca.ion pile-up, thereby ca.sing in sire recrysta.liza.ion. a. stra.n ra.es exceeding 0.16 s-1, there is no intensive blocking of disloca.ions, lea.ing to a.direct stra.n ra.e dependence of stra.n resista.ce.

Knowledge rega.ding ea.thqua.e ha.a.ds a.d seismicity is crucia. for crisis ma.a.ement, a.d the occurrence of foreshocks, seismic a.tivity pa.terns, a.d spa.iotempora. va.ia.ions in seismic a.tivity ha.e been studied. Furthermore, the estima.ion of the region-time-length (RTL) pa.a.eter ha. been proposed to detect seismic quiescence before the occurrence of a.la.ge ea.thqua.e. In a.dition, the time-to-fa.lure method ha. been used to estima.e the time occurrence of la.ge ea.thqua.es. Hence, in this study, to ga.n deeper insight into seismic a.tivity in the southern Za.ros region, we utilized the RTL a.gorithm to identify the quiescence a.d a.tiva.ion pha.es lea.ing to the Fin doublet ea.thqua.es. Tempora. va.ia.ions in the RTL pa.a.eter showed two significa.t a.oma.ies. One corresponded to the occurrence time of the first ea.thqua.e (2017-12-12);the other a.oma.y wa. a.socia.ed with the occurrence time of the second event (2021-11-14). Ba.ed on a.nega.ive va.ue of the RTL pa.a.eter observed in the vicinity of the Fin epicenters (2021), seismic quiescence (a.decrea.e in seismicity compa.ed to the preceding ba.kground ra.e) wa. identified. The spa.ia. distribution of the RTL prognostic pa.a.eters confirms the a.pea.a.ce of seismic quiescence surrounding the epicenter of the Fin doublet ea.thqua.es (2021). The time-to-fa.lure method wa. designed using precursory events tha. describe the a.celera.ion of the seismic energy relea.e before the ma.nshock. Using the time-to-fa.lure method for the ea.thqua.e ca.a.og, it wa. possible to estima.e both the ma.nitude a.d time of fa.lure of the Fin doublet. Hence, the time-tofa.lure technique ca. be a.useful supplementa.y method to the RTL a.gorithm for determining the cha.a.teristics of impending ea.thqua.es.

a.new la.er-pla.ma.deposition method ha. been developed for the pla.ma.chemica. deposition of ha.d silicon ca.bonitride coa.ings on sta.nless steel substra.es from the hexa.ethyldisila.a.e (HMDS) Si2NH(CH3)6 vapor in a high-speed Ar and Ar + 10 vol.% He gas stream at the HMDS gas flow activation after the laser beam focus. The method allows depositing silicon carbonitride coatings at the rate of 0.4 - 1.2 μm·min-1, i.e. ~2 times higher than that at introducing HMDS in the laser beam focus zone. The properties of the prepared coatings have been studied by the methods of IR and Raman spectroscopy, atomic force microscopy, nanoindentation and X-ray diffraction (XRD) analysis. Studying the film structure with the use of XRD showed that the prepared silicon carbonitride coatings are X-ray amorphous. It has been found that the coating deposition rate and the structure of coatings depend on the process parameters: HMDS flow rate and plasma-generating gas (argon or (Ar +a.> He). The method allows depositing SiCN films at a high speed and a hardness of 20a. style="font-fa.ily:Verda.a."

高温会导致混凝土微细观结构损伤劣化,进而导致混凝土力学性能下降。本工作利用计算机层析成像(CT)技术对高温后掺加玻化微珠的再生混凝土(Recycled a.grega.e concrete mixed with gla.ed hollow bea.s, GHB-Ra.)试件孔隙结构特征进行识别,基于CT扫描与三维重构建模提取并分析了混凝土孔隙结构的特征参数,同时利用灰色关联理论探究孔隙结构特征参数对混凝土残余抗压强度的影响程度。研究结果表明,温度会影响GHB-Ra.内部孔隙结构,内部孔隙孔径及表面积随温度升高而增大,温度的升高也会影响混凝土孔隙均匀性,加剧孔隙不均匀性分布;玻化微珠(Gla.ed hollow bea.s, GHB)对混凝土温度传导的阻碍作用明显,GHB的掺入改善了混凝土的孔隙结构,减弱了高温导致的孔隙畸化;孔隙尺寸、孔隙球体度及孔隙表面积与残余抗压强度的灰色关联度均在0.55以上,表明孔隙结构参数与残余抗压强度关联性较好。
