Film Layer Structure and Wear Resistance on High Strength Room Temperature Blackening of Cu-Se-P System ZHANG Yu-feng1,WANG Jian-cheng1,ZHOU Hou-qiang1 (1.Wuhan Ordnance Noncommissioned Officer School, Wuhan 430075 ,China) 摘要:In this paper,the high strength room temperature blackening film on steel surface were prepared, the structure and the forming principle of the film were studied. The Cu......
TOUGHENING OF IN SITU SYNTHESIZED MoSi2-SiC COMPOSITE AT ROOM TEMPERATURE J.Zhu1,L.Q.Zhang2,Z.Q.Sun3,X.W.Fu2,W.Y.Yang2 (1.School of Materials, Tsinghua University, Beijing 100083, China;2.School..., it is concluded that the toughening of such compositeat room temperature can be attributed to the high interfacial binding energy, the re-finement of the MoSi2 matrix and the defection and bridging......
and annealing twins at room temperature, at the same time, a significant amount of annealing twins and stacking faults are observed by transmission electron microscopy (TEM). Mechanical twins play a dominant role during deformation, and result in excellent mechanical properties. Key words:cold rolling reduction; annealing temperature; TWIP (twinning induced plasticity) steel; twinning; [全文内容正在添加......

Abstract: Twin roll cast ZK60 alloy strip/sheet with final thickness of 0.5 mm was prepared, and effect of rolling temperature on microstructure and texture development was investigated using OM and XRD......
, Taiyuan 030024, China摘 要:Zr 55 Al 10 Cu 30 Ni 5 bulk metallic glass was rolled up to 95% in thickness reduction at room temperature, and the dependences...Crystallization Behavior of Zr55Al10Cu30Ni5 Bulk Metallic Glass Rolled at Room TemperatureYong Hu 1,2) , Jinfu Li 1) , Pengna Zhang 1) and Yaohe Zhou 1) 1) State Key Laboratory of Metal Matrix......
temperature at 3, 6 and 16 m/min rolling speeds into 1 mm thickness. The results indicate that the microstructures achieved by rolling at low temperature or at low rolling speed are composed of many prismatic regions divided by shear strips due to pile-up of twin crystals; the prismatic regions increase at elevated rolling temperature or at high rolling speed, and finally all are composed of equiaxed......
to the surface to reduce the influence of gravity. We applied 50 images per second to record the spreading process. Our measurement was carried out in the open air at room temperature of (24±1...; Dynamic wetting of rolling oil on aluminum surfaces ZHOU Ya-jun(周亚军), ZHOU Hong-hui(周宏慧) (School of Mechanical and Electrical Engineering, Central......
DIMENSIONAL INSTABILITY OF LD31 Al ALLOY WELDMENTS AT ROOM TEMPERATURE AND AFTER THERMAL CYCLES X.S.Liu1,X.D.Sun2,W.L.Xu1,H.Y.Fang1,X.T.Tian1 (1.National key Laboratory of Advanced Welding... aluminum alloy weldments at room temperature and after thermal cycles was studied by use of light interference and CMM(three-coordinate measuring machines). At the same time, distortion mechanism......
and rolling process on the properties and microstructures of Ti-26 (Ti-15V-3Al-3Cr-3Sn-Forming) sheet was studied. The results show that the best rolling temperature for Ti-26 alloy... by vacuum consumable arc furnace melting for two times. Plate with thickness of 4 mm was fabricated by hot rolling above the phase transformation temperature after the ingot was originally forged at 1 150......
