1PHYSICAL SIMULATION OF INTERFACIAL CONDITIONS IN HOT FORMING OF STEELS显示文摘In the last few years,substantial experimental simulation and mumerical modelling hare been carried out in IMMPETUS to characterise the interfacial heat transfer and friction conditions during hot forging and rolling of steels. Emphasis has been placed on the influence of the oxide scale which forms on the steel workpiece. In the present paper, the experimental methods used for investigating interfacial heat transfer and friction conditions are described. Theses include hot flat rolling of steel slabs and hot axi- symmetric forging of steel cylinders and rings.Temperature measurements and computations demon- strate that for similar conditions, similar conditions, the effective interfacial heat transfer coefficients (IHTC) derived for hot rolling are significantly higher than those for forging, mainly due to the contribution of scale cracking during rolling. On the basis of experimental observations and numerical analysis,physical models for interfacial heat transfer in forging and rolling have been established. In addition, hot' sandwich' rolling and hot tensile tests with finite element modelling have been carried out to evaluate the hot ductility of the oxide scale.The results indicate that the defomation, cracking and decohesion behaviour of the oxide scale depend on deformation temperature, strain and relative strengths of the scale layer and scale - steel interface.Finaly, friction results from hot ring compression tests and from hot rolling with forward/backward slip measurements are reported.Y.

2Ikaros in B cell development and function显示文摘The zinc finger transcription factor,Ikaros,is a central regulator of hematopoiesis.It is required for the development of the earliest B cell progenitors and at later stages for VDJ recombination and B cell receptor expression.Mature B cells rely on Ikaros to set the activation threshold for various stimuli,and to choose the correct antibody isotype during class switch recombination.Thus,Ikaros contributes to nearly every level of B cell differentiation and function.MacLean Sellars Philippe Kastner Susan Chan 2011World Journal of Biological Chemistry2011,2,6:3
