Ultrafine Grained Duplex Structure Developed by ART-annealing in Cold Rolled Medium-Mn Steels
Springer Science and Business Media LLC - Tập 21 - Trang 208-214 - 2014
Jie Shi, Jun Hu, Chang Wang, Cun-yu Wang, Han Dong, Wen-quan Cao
The microstructural evolutons of the cold rolled Fe-0. 1C-5Mn steel during intercrical annealing were examined using combined advanced techniques. It was demonstrated that intercrtical annealing results in an ultrafine granular ferrite and austenite duplex structure in cold rolled 0.1C-5Mn steel. The strong partitioning of manganese and carbon elements from ferrite to austenite was found during in...... hiện toàn bộ
Influence of Cast Dimension on Rotary Bending High Cycle Fatigue Properties of Single Crystal Superalloy
Springer Science and Business Media LLC - Tập 20 - Trang 98-102 - 2013

FEM Analysis of Rolling Pressure Along Strip Width in Cold Rolling Process
Springer Science and Business Media LLC - Tập 14 - Trang 22-26 - 2007
Xiang-hua Liu, Xu Shi, Shan-qing Li, Jian-yong Xu, Guo-dong Wang
Using 3-D elastic-plastic FEM, the cold strip rolling process in a 4-high mill was simulated. The elastic deformation of rolls, the plastic deformation of the strip, and the pressure between the work roll and the backup roll were taken into account. The distribution of rolling pressure along the strip width was obtained. Based on the simulation results, the peak value of rolling pressure and the l...... hiện toàn bộ
Optimization of submerged entry nozzle parameters for ultra-high casting speed continuous casting mold of billet
Springer Science and Business Media LLC - Tập 29 - Trang 44-52 - 2022
Pei Xu, Yong-zhi Zhou, Deng-fu Chen, Mu-jun Long, Hua-mei Duan
Controlling the flow behavior in the mold in an appropriate way is the basis for realizing the billet ultra-high speed continuous casting. Based on the new proposed physical water modeling experiment considering the effects of solidified shell and hydrostatic pressure, the flow behavior in the mold with cross section of 160 mm × 160 mm during continuous casting of billet is regulated by optimizing...... hiện toàn bộ
Characterizing the Structure Evolution of Tertiary Scale during Simulated Coiling by EBSD
Springer Science and Business Media LLC - Tập 21 - Trang 215-221 - 2014
Sheng LIU, Hui-bin WU, Xiao LI, Hai-tao JIANG, Di TANG
Effect of heat input on microstructure and mechanical properties of dissimilar joints of AISI 316L steel and API X70 high-strength low-alloy steel
Springer Science and Business Media LLC - Tập 24 - Trang 1248-1253 - 2017
Ebrahim Mortazavi, Reza Amini Najafabadi, Amirhossein Meysami
Control of Hydrogen During ESR Process
Springer Science and Business Media LLC - Tập 20 - Trang 7-11 - 2013
Chen Yan, Ying Li, Bei-yue Ma
Experimental and numerical studies were carried out for the behavior of hydrogen in a three-phase electroslag furnace using double electrode series technique during electroslag remelting (ESR) process. The effect of water vapor content of furnace gas on the hydrogen content of ingots was studied through the “gas-slag-metal” osmosis experiment. Based on the experimental results, a mathematical mode...... hiện toàn bộ
Tensile Properties of TWIP Steel at High Strain Rate
Springer Science and Business Media LLC - Tập 16 - Trang 81-86 - 2009
Rong-gang XIONG, Ren-yu FU, Yu SU, Qian LI, Xi-cheng WEI, Lin LI
Electromagnetic Dam in Twin-Roll Strip Caster
Springer Science and Business Media LLC - Tập 13 - Trang 27-29 - 2006
Yong-lin Ma, Bao-feng Wang, Bao-wei Li, Guo-dong Wang, Xiang-hua Liu
The electromagnetic dam (EMD) in twin-roll strip caster was simulated with FEM. The results show that the direction and magnitude of Lorentz force distributing in the EMD changed in a period. The negative part is about 30% of the positive part, and the acting time of the negative force is about 40% of a period. In order to prevent the liquid steel from leaking efficiently, the distance between two...... hiện toàn bộ
