Influence of a multi-step process on the thickness reduction error of sheet metal in a flexible rolling processYi Li1,2,Ming-zhe Li1,2,Kai Liu1,21. Dieless Forming Technology Center, Roll Forging Institute, Jilin University2. College of Materials Science and Engineering, Jilin University摘 要:Flexible rolling is a forming process based on thickness......
Effects of the width and thickness of slabs on broadening in continuous castingJian-xun Fu1,2), Jing-she Li1), and Hui Zhang2) 1) School of Metallurgical and Ecological Engineering, University... Numerical simulations were performed to study slab broadening in the secondary cooling zone. The effects of slab width and thickness on slab broadening were considered. The obtained results reveal......

Effect of W/C ratio and cover thickness on polarization characteristics of embedded steel in mortar Kyung-Man MOON1, Sung-Yul LEE1, Myung-Hoon LEE2, Yun-Hae KIM1 1. Department...; Abstract: The effects of cover thickness and W/C (water-to-cement) ratio on polarization properties of embedded steel bar were investigated......
were prepared by wet ball milling method, their magnetoelectric (ME) effect was studied as a function of their constituents and modulation frequency. The results show that the ME coefficient increases as a function of modulation frequency from 400 to 1000 Hz and the ME characteristics of ME curves are also modified because the electrical conductivity of the CoFe2O4 phase is sensitive......
