Effect of Addition of Al on Crystal Structure Microtexture and Magnetostriction Coefficient in Tb0.3 Dy0.7 Fe1.95 Alloy ZUO Liang1,Huang Jimin2,ZHAO Zengqi2,WU Shuangxia2,Jiang Liping1 (1.School... in the microtexture as addition of A1 increases.At a certain magnetic field, magnetostriction coefficient decreased as addition of Al increased. Key words:magnetostriction; Tb-Dy-Fe alloy; microtexture; rare......
of the internal friction coefficient of the granular system under different normal pressures were obtained by self-designed shear test. By the granule volume compression test, the accurate discrete element... the microscopic view. Based on the DEM, the influence of granule diameter, surface friction coefficient, normal pressure and shear velocity on the internal friction coefficient of the granular system were studied......
Effect of Carbon Nanotube Orientation on Mechanical Properties and Thermal Expansion Coefficient of Carbon Nanotube-Reinforced Aluminum Matrix CompositesZ.Y.Liu1,2,B.L.Xiao2,W.G.Wang3,Z.Y.Ma21.... fabricated by friction stir processing(FSP) and FSP-rolling, respectively. The CNT/2009 Al composites with aligned CNTs showed much better tensile properties at room temperature and elevated temperature......

Impact coefficient and reliability of mid-span continuous beam bridge under action of extra heavy vehicle with low speedLIU Bo(刘波)1, 2, WANG You-zhi(王有志)1, HU Peng(胡朋)3, YUAN Quan(袁泉)1(1. School... coefficient reaches a high value, which should not be disregarded in bridge safety assessments. Considering that no specific law exists between the impact coefficient and vehicle speed, vehicle speed......
- is the time just before impact; τ+ is the time just after impact and is the coefficient of restitution. The time of impact is assumed to be short as said before. So, the impact process can be considered instantaneous. The effect of the coefficient of restitution law is to make impact oscillator model non-smooth and non-differentiable at the impact point. In fact, the impact process makes......
Quantitative effects of phase transition on solute partition coefficient,inclusion precipitation, and microsegregation for high-sulfur steel solidificationLintao Gui1,2,Mujun Long1,2,Shixin... elements at the solid-liquid interface. The effect of the phase transition of high-sulfur free-cutting steel is quantified in the present work for the solute partition coefficient(ki), inclusion......

significant influence on the humidification vibration deformation coefficient. When initial consolidation stress is not large enough to destroy the loess structure, with initial consolidation stress increasing, the humidification vibration deformation coefficient decreases. On the contrary, the humidification vibration deformation coefficient increases with initial consolidation stress increasing. 4......
