28 August 2012; accepted 25 October 2012 Abstract: A ‘bone-like’ hollow component with curved axis and complicated cross-sectional geometry was used as the object. The experimental setup... but also avoid fracture at the corner caused by the large expansion rate and wrinkle in the transition zone of different cross sections. The loading path has a serious effect on the material flow......

INFLUENCE OF COLD ROLLING TECHNOLOGY ON TEXTURE EVOLUTION OF IF STEEL X.H.Liu1,J.X.Li1,G.D.Wang1 (1.State Key Laboratory of Rolling & Automation, Northeastern University, Shenyang 110006, China) Abstract:Two kinds of cold rolling experiments, single cold rolling and double cold rolling, werecarried out on one titanium stabilized interstitial free (IF) steel that has been warmrolled at ferrite......
A STUDY ON THE DECLINE FUNCTION OF THE PROPERTIES OF CEMENT COMPOSITE SUFFERING iN THE FREEZING-THAWING CIRCLE邓德华摘 要:<正> This Paper is a study on the rule of the decline of properties of cement composite being damaged in the freezing thawing circle. By analyzing the damaging process of cement composite in such a circle,the author sets up a model......
with uniform thickness has great significance in rolling industries, but it is daunting to accomplish existing technical matters, such as pair cross mill and high-crown control mill. The past several... models (e.g., rolling force model, temperature model and thermo-mechanical coupling model) are avoided.
