沉积复合OTFC试样的氧化层形貌有如下特征：(1)氧化层绝大部分致密、完整、与基体附着良好，晶粒细小（图7a，7b）；(2)在短时间(15s)沉积2O3 OTFC试样的局部表面出现了不均匀氧化（图7c，7d），但只是在沉积Cr/Y=4/1膜试样的局部表面产生了类似无涂层Fe25Cr上剥落的厚膜（图7d）；(3)沉积2O3(Cr/Y=2/1) 60s（图7e）与15s（图7c）的结果不同，前者整个试样表面氧化产物颗粒细小，无粗大氧化物颗粒形成；(4)沉积2O3(Cr/Y=2/1) 60s和2O3(Al/Y=3.6/1)薄膜的试样由于氧化增重非常少，氧化层很薄，刻印着涂层中局部出现的裂纹（图7e，7f），这种印迹的保留可能反映着传质机制的改变，即新氧化物由在外表面形成转变为在外表面以下形成。

The microfracturing process of Jinping marble specimen in Sichuan province under uniaxial compression is recorded by using the testing scheme. Quantitatively investigated the propagation and coalescent of cracks at meso-scale with digital technology, the basic geometric information of rock microcracks such as area, angle, length, width, perimeter, are obtained from binary images after segmentation. The failure mechanism of specimen under uniaxial compression with the quantitative information is studied from macro/micro scopic perspective. The result shows that during the damage of the specimen the distribution of microcracks in the whole specimen are still subjected to exponential distribution with some microcracks concentrated in certain regions.

应用于四川锦屏大理岩预制裂纹试样中进行单轴压缩破坏全程的数字化试验，对微裂纹的萌生、生长及贯通过程进行数字化定量分析，得到试样在受荷过程中微裂纹的面积、方位角、长度、宽度和周长基本几何数据，从宏细观角度描述了岩石试样单轴压缩过程中的破坏机制，并分析得出试样单轴受压破坏过程中虽然微裂纹在某些区域集中，但在整个试样中微裂纹的统计分布依然是服从某一指数分布的这一结论。

The experimental results show that: the failure mode of strengthened beam at elevated temperature can be classified as flexure failure mode or flexure-shear failure mode, and the failure mode of strengthened beam at high temperature may be different from that at room temperature; and although the load supported by the strengthened specimen is larger than that supported by the unstrengthened specimen, the fire resistance of the strengthened specimen is still larger than that of the unstrengthened specimen, due to the influence of fire insulation.

结果表明：高温下该类构件的破坏形态大致可分为受弯破坏和弯剪破坏两类，常温下发生弯曲破坏的加固构件有可能在高温下出现破坏形态的转变；虽然加固构件所承受的荷载明显大于未加固构件，前者由于防火涂料的保护，其耐火极限仍大于后者。

The effects of strain rate on plastic formation and dynamic recrystallization of 7050 aluminum alloy were discussed. The results show that the deformation of the specimen is inhomogeneous, and the effective strain in the center of the specimen is maximum. The deformation inhomogeneity increases with the increase of strain rate. The effective stress of specimen is inhomogeneous. As the strain rate increases, the minimum stress value moves from the drum-shaped region to the heart of specimen. The standard deviation of dynamic recrystallization grain size decreases with the increase of strain rate.

模拟结果表明，热变形过程中，试样的各个部位的变形分布不均匀，心部的等效应变最大，变形的不均匀性随应变速率的增大而增大，但是变化的程度不大；试样内部各部位的应力大小分布不均匀，随应变速率的增大，最小应力值由自由变形的鼓形区域逐步向心部移动；动态再结晶晶粒尺寸标准偏差随应变速率的增加而减小。

The fatigue is analyzed for the SENT specimen of TA6V titanium alloy at different stress ratio and on different stress level by the general finite element analysis software ANSYS. The dangerous fatigue location is predicted by the nodal stress Y-direction of the hemicycle notch for TA6V titanium alloy SENT specimen. Based on the local stress-strain method and the material S-N graph, the nominal stress-strain of the specimen is converted to the local stress-strain of the dangerous location by the elastic and plastic finite element analysis, thus the fatigue life is estimated by Miner fatigue damage accumulation theory and compared with the fatigue test of small crack growth.
