After the addition of carbon, the microhardness in the grain boundary is about 150 MPa higher than that in the grain. The fracture type of pure Mo is intergranular fracture, the grain boundary strength of Mo-C alloy is strengthened due to the addition of carbon and the fracture type is changed to transgranular fracture, transcrystalline fracture and a large number of cleavage planes and steps are observed on the bending fracture surface. But if the carbon content is too high, the carbide precipitation will be severe at grain boundaries and is deleterioated to the ductility of the alloy.

添加碳后，合金的晶界显微硬度比合金的晶内显微硬度高150MPa左右；纯钼的断裂方式以沿晶断裂为主，添加碳后，由于合金的晶界强度得到提高，合金的断裂方式变成以穿晶断裂为主，断口上有大量的解理面，具有明显的河流状花样和解理台阶，且塑性越好的断口，撕裂岭也越多；当添加的碳含量偏高时，在晶界处产生了大颗粒的碳化物，这种大颗粒的碳化物会降低合金的塑性。

As is well documented elsewhere, the Real is inextricably linked with the registers of the Symbolic and the Imaginary and together these form a basic triadic structure for all Being.

像在其他地方已经很好地指出的那样(e.g。 Fink， 1995)，真实界无法避免与符号界及想像界的连结，这三者也为所有人类形成了基要的三位一体结构。

After tempering at 700℃, bainitic ferrite laths started to coarsen. The grain boundary characteristics and effective grain size of ULCB steels can be measured by EBSD technique.

晶界特征结果显示，轧态和回火态组织均存在大量低能量小角度晶界和低Σ值重位点阵晶界。

Quasi-convex relaxation algorithm, which aims to solve ordinary constraint global optimization problems, is produced by a combination of branch-and-bound method with quasi-convex lower bound and quasi-concave upper bound functions developed from quasi convex-concave extension. This algorithm extends the interval algorithm with box constraint to general constraint global optimization problem.

利用拟凸-凹扩张中构造出的函数的拟凸下界函数和拟凹上界函数，与分枝定界方法相结合，建立了求一般约束全局优化问题的拟凸松弛算法，这一算法是将盒子约束的区间算法推广到一般约束优化问题中。

The results show that the relationship betweentotal potential energy and time step exhibits periodic characteristic when sigma-3symmetric twist grain boundary model and sigma-3 tilt grain boundary model slide atOK. But for sigma-13 asymmetric tilt grain boundary, the relationship between totalpotential energy and time step exhibits damp surge characteristic.

结果发现，∑3对称扭转晶界模型与∑3对称倾侧晶界模型在0K滑动时，系统的势能与计算步数之间的关系曲线呈现周期性变化的规律，而∑13非对称倾侧晶界模型系统的势能与计算步数之间的关系却呈现阻尼振荡特征的变化规律。

Results of EBSD show that most of the reversed austenite in the steel treated by QT distribute along the grain boundary, but in the steel treated by two--phase region heat treatment the austenites distribute uniformly along all kinds of boundaries, especially also along the lath martensite boundary in the grain, so the cryogenic toughness can be also improved even the amount of austenitic is lower than that in the steel treated by QT process.

EBSD结果则表明：经两相区处理，回转奥氏体不仅在晶界和板条束界形成，也在晶内的板条界上形成，因此即便在其含量低于淬火+回火处理的条件下， 9Ni钢的低温韧性也有明显提高，证明回转奥氏体的分布也是影响9Ni钢低温韧性的一个主要因素。
