Using dislocation-based constitutive modeling in three-dimension crystal plasticity finite element(3D cPFE)simulations,co-deformation and instability of hetero-phase interface in different material systems were herein studied for polycrystalline metal matrix composites(MMcs).Local stress and strain fields in two types of 3layer MMcs such as fcc/fcc cu-Ag and fcc/bcc cu-Nb have been predicted under simple compressive ***,more severe strain-induced interface instability can be observed in the fcc/bcc systems than in the fcc/fcc systems upon refining to metallic nanolayered composites(MNcs).By detailed analysis of stress and strain localization,it has been demonstrated that the interface instability is always accompanied by high-stress concentration,i.e.,thermodynamic characteristics,or high strain prevention i.e.,kinetic characteristics,at the hetero-phase *** then follows that the thermodynamic driving forceg and the kinetic energy barrier q during dislocation and shear banding can be adopted to classify the deformation modes,following the so-called thermo-kinetic *** by inserting a high density of high-energy interfaces into the cu-Nb composites,such thermo-kinetic integration at the hetero-phase interface allows a successful establishment of MMcs with the high△g-high q deformation mode,which ensures high hardening and uniform strain distri-bution,thus efficiently suppressing the shear band,stabilizing the hetero-phase interface,and obtaining an exceptional combination in strength and *** hetero-phase interface chosen by a couple of thermodynamics and kinetics can be defined as breaking the thermo-kinetic correlation and has been proposed for artificially designing MNcs.

微生物在冰川碳循环中发挥着重要作用,然而当前缺乏对冰尘微生物参与的溶解性有机质(DoM)转化过程的深入研究.本研究利用了分析化学和微生物生态学的主流手段——超高分辨率的傅里叶变换离子回旋共振质谱(FT-IcR MS)和微生物16S rRNA测序技术,分别解析了培养实验中青藏高原龙匣宰陇巴冰川冰尘的DoM分子组成以及微生物群落,并耦联两者构建了复杂微生物参与的冰川DoM转化过程.研究结果表明:在60天的培养实验中,冰尘DoM的生物可利用性随着培养时间的增加而降低,微生物对DoM组分的转化过程可分为三个阶段.在前7天里,微生物选择性降解了具有较高H/cwa和较低o/cwa的DoM分子,且群落变化不大;在第15至30天期间,DoM组分保持稳定,但微生物多样性增加;到培养末期, DoM分子在微生物作用下转化为难降解的惰性DoM组分,这些惰性DoM具有更高的芳香指数和o/cwa、更低的H/cwa以及含有更多的杂原子.此外,培养实验揭示了冰尘中cyanobacteria、Bacteroidota、gammaproteobacteria、Firmicutes和Actinobacteriota等类群协同作用于DoM组分转化,使其变得惰性.本研究揭示了冰尘中微生物转化DoM组分的过程,为理解微生物在冰川有机碳循环中的作用提供了新见解.

In this paper, a finite element model was developed for a turbine blade with thermal barrier coatings to investigate its failure behavior under cyclic thermal loading. Based on temperature and stress fields obtained from finite element simulations, dangerous regions in ceramic coating were determined in terms of the maximum principal stress criterion. The results show that damage preferentially occurs in the chamfer and rabbet of a turbine blade with thermal barrier coatings and its thermal fatigue life decreases with the increase of thermal stress induced by high service temperature.

Tic_(x)is an excellent composite strengthening particle and grain refiner for Al ***,the stability of Tic_(x)is poor when solute Si exists in Al alloy melts,which significantly depresses its strengthening and grain refining *** this work,the destabilization mechanisms of the Tic_(x)particles in Al-Si alloy melt with a composition of Al-7Si-7.5Tic were explored via experiments,first-principles calculations and thermodynamic *** experimental results show that Si atoms diffuse into Tic_(x)and Ti atoms are released into the Al melt to form a Ti-rich transition zone during the insulation of Tic_(x)in Al-Si melt,and the TiAlySiz and Al_(4)c_(3)phases are solidified in the Ti-rich zone and at Ti-rich zone/Tic_(x)interface,*** first principles calculations show that the low formation energy of c vacancies facilitates the rapid diffusion of Si atoms in Tic_(x),while the doping of Si atoms reduces the energy barrier of diffusion of Ti atoms in Tic_(x)and promotes the formation of Ti-rich *** thermodynamic calculations show that the wide crystallization temperature range of the destabilized product TiAlySiz phase is the key to continuous decomposition of Tic_(x)*** addition,the driving force of the main destabilization reaction of Tic_(x)in the Al-Si alloys is about 44 times higher than that in the Al alloys without Si *** indicates that the presence of solute Si remarkably promotes the subsequent decomposition process of Tic_(x)in the Al-Si alloy melts.
