材料科学技术（英文）

Isothermal aging behaviours of a CuZnAl shape memory alloy have been investigated by means of dilatometry.The length of the specimens during isothermal aging from 190 to 280℃ increases with the aging time at each temperature.The isothermal aging kinetics fits in Avrami equation and the time exponent...

Effect of Ni on Sintering Characteristics of Short Cast Iron Fibre

LI Dongchun TIAN Yongjun CHEN Shizhen YU Dongli HE Julong ** Yanshan University , Qinhuangdao , 066004 , China+ To whom correspondence should be addressed

材料科学技术（英文）

Nickel,as the carrier through which Fe atoms diffuse,obviously enhances the densification of sintered compact containing short cast iron fibre. When Ni content is above 4.5 wt-% there are some austenites in microstructure at room temperature, discontinuous cementite networks at the interfaces betwee...

Transverse Distributions of Front and Back Tension Stresses in Cold Strip Rolling

LIU Hongmin LIAN Jiachuang ** Yanshan University , Qinhuangdao , Hebei Province , 066004 , China+ To whom correspondence should be addressed

材料科学技术（英文）

In this paper,such a new lateral displacement function is proposed that the lateral flow velocity is con- tinuous at the entry and the exit of deformation zone.A new kind of finite strip method—the third power B-spline finite strip method—is put forward to simulate strip rolling process.Front and ba...
