Influencing Factors For Obtaining Ultrafine Austenite Grains With Initial Microstructure Of Warm-Rolled Ferrite/Pearlite

S.J. Yao , L.X. Du , X.H. Liu , G.D. Wang

金属学报(英文版)

Three warm-rolled ferrite/pearlite microstructures were prepared by rolling at 500℃, and the austenitizing characteristics were discussed in conjunction with deformation during the heating stage. The results indicated that the final austenite grain size was sensitive to the deformation direction of ...

Numerical Simulation Of Molten Pool And Control Strategy Of Kiss Point In A Twin-Roll Strip Casting Process

G.M. Cao , C.G. Li , Z.Y. Liu , D. Wu , G.D. Wang , X.H. Liu

金属学报(英文版)

Coupled turbulent flow, temperature fields of the twin-roll casting strip process were simulated by three-dimensional finite element method. Based on the heat balance calculation and using inverse methods between the simulations and real experiments, the relational models among casting speed, locati...

MECHANICAL STABILIZATION OF DEFORMED AUSTENITE DURING CONTINUOUS COOLING TRANSFORMATION IN A C-Mn-Cr-Ni-Mo PLASTIC DIE STEEL

D.S. Liu , G.D. Wang , X.H. Liu and G.Z. Cui(The State Key Laboratory of Rolling and Automation , Northeastern University , Shenyang 110006 , China)

金属学报(英文版)

The influence of prior austenite deformed at different temperature on the subsequent continuous cooling bainitic transformation has been investigated in an C-Ma-Cr-Ni-Mo plastic die steel. The results show that the prior deformation in low temperature region of austenite retards significantly the ba...

SIMULATION OF THE TWIN ROLL STAINLESS STRIP CASTING PROCESS

Y.C. Miao , X.M. Zhang , G.D. Wang

金属学报(英文版)

The position of the solidification completed temperature of twin roll stainless strip casting process is very important to the quality of the casting strip. In order to control this position, the solidification completed temperature should be known at first.The present paper first simulated dendriti...

INFLUENCE OF COLD ROLLING TECHNOLOGY ON TEXTURE EVOLUTION OF IF STEEL

J.X. Li , X.H. Liu , G.D. Wang

金属学报(英文版)

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 temperature. The main aim was to investigate the evolution of rollingand annealing textures from the well kn...
