Flow characteristics of variable hydraulic transformerYANG Guan-zhong(杨冠中), JIANG Ji-hai(姜继海) (Department of Fluid Power Control and Automation, Harbin Institute of Technology, Harbin 150080, China)Abstract:A new kind of hydraulic transformer, called variable hydraulic transformer (VHT), is proposed to control its load flow rate. The hydraulic transformer evolves from a pressure transducer......
Microstructure evolution and mechanical property characterization of a nickel-based superalloy at the mesoscopic scaleQiang Zhu1,Gang Chen1,Chuanjie Wang1,Lukuan Cheng1,Heyong Qin2,Peng Zhang11... quantitative statistics results showed that as the aging time increases,the particle size and volume fraction of the γ" phase increase.As the grain size increases,the flow stress decreases due to the dwindling......

Preparation and magnetic property of multi-walled carbon nanotube/α-Fe2O3 composites CHEN Chuan-sheng(陈传盛)1, 2, LIU Tian-gui(刘天贵)3, CHEN Xiao-hua(陈小华) 2, LIN Liang-wu(林良武)1, LIU Qi...: In order to attain new functional nanomaterials with good magnetic property, multi-walled carbon nanotubes/hematite (MWNTs/α-Fe2O3) composites were synthesized using the co-deposition method. MWNTs......
microstructure and mechanical property of the experimental alloy was analyzed in hot-compression procedure. The experimental results show that the strain rate and the deformation temperature are the key parameters of deformation activation energy. When the deformation temperature is definite, the relation between flow stress and strain rate is liner, and the variation of deformation activation......
’s transfiguration under the force or flow. The rheological property of medical gum can be used to forecast and explain the flow, transfiguration and quality change when the gums are treated...: peach gum; supernatant; rheological property 1 Introduction The peach gum, a kind of transparent gum, is excreted from the trunk of Prunnus dulcis under environmental stress and belongs to edible......
