Driven by high frequency and multi-directional shot peens, dislocations of various orientations proliferate into the metal, and accumulate in high density in the surface layer of a shallow depth. Migration, generation and annihilation of dislocations dictate the evolution of mobile dislocation density.

At 1273K, the density of dislocations were considerably decreased in deformed TiAlMnNb alloy, twinning and 11 superdislocations were hardly observed, but few 1/212 superdislocations and 01 perfect dislocations were found in deformed TiAlMnNb alloy. In high temperature range, brittle-to ductile transition had already occurred in deformed TiAlMnNb alloy, unpinning and climbing were the dominant deformation behavior in TiAlMnNb alloy. In the same way as TiAlMnNb alloy, different distinguishing feature the dislocation configuration at low, intermediate and high temperatures emerged in deformed TiAlMnNbB alloy.
在中温区域,合金中位错组态变化可分为两个小区域,在673K以下,合金的位错组态有孪晶、1/210单位位错和少量的11超点阵位错;这一温度区间内孪晶和位错密度都大大提高,不同系统的孪晶相互交割阻碍了孪生的继续发展,不同方向的位错相互交割阻碍位错进一步滑移,同时孪晶界面也阻碍了位错的运动。

The results show that the composite is dense and silicon particles are distributed uniformly. Transmission electron microscope observations show that stacking faults with high density, twins and dislocations are found in silicon particles. The Si-Al interfaces are well-bonded and no interface reactants are found. The dislocations and eutectic silicon precipitates are observed in LD11 matrix. Sip/LD11 composite has low density of 2.4 g/cm3, low coefficient of thermal expansion of 8.1×10-6/K, high thermal conductivity of 161.3 W/, and the annealing treatment can reduce the CTE and improve the thermal conductivity.
研究结果表明:复合材料组织致密,颗粒分布均匀;透射电镜观察发现,在Si颗粒内部存在高密度的层错,同时还存在孪晶和位错; Si-Al界面结合状况良好,无界面反应物; LD11铝合金中存在位错和析出的共晶Si;复合材料具有低密度(2.4 g/cm3),低热膨胀系数(8.1×10-6/K),高热导率161.3 W/(m·K的特性,可以通过退火处理进一步降低其热膨胀系数,提高热导率。

The causes of shield tunnel defections could be divided into six branches: the segment dislocations, lining material deterioration and seepage. etc. Fault trees are also founded to illustrate each branch. 23 quantitative elements from the fault trees are selected to serve as the diagnosis indexes, all of which could be applied in engineering practice. By using the AHP method, a 3-level diagnosis index system is established. Afterwards, the procedure of setting up the quantitative judging criteria is given, as well as the relative index weight of index layer, by using the improved Analytic Hierarchy Process-multiplication scale method. At last, the values of corresponding parameters of membership functions are set, with the Cauchy distribution model.
