1Design of TRIP Steel With High Welding and Galvanizing Performance in Light of Thermodynamics and Kinetics显示文摘A new type of transformation induced plasticity (TRIP) steel with not only high strength and high ductility but also superior welding and galvanizing properties was designed and developed recently. Low carbon and low silicon content were preliminarily selected with the aim of meeting the requirements of superior quality in both welding and galvanizing. Phosphorus was chosen as one of the alloying elements, because it could reduce carbon activity in cementite and increase the stability of austenite. In addition, the possibility of phosphorus segregating at grain boundary was also discussed by thermodynamics as well as kinetics. Phase diagram was estimated at high temperature and the composition of the steel was then selected in the hyperperitectic range to avoid problems, which might occur in sheet steel continuous casting. Phase diagram in the inter-critical temperature was estimated for the steel to obtain the starting temperature of fast cooling. For understanding the minimum rate of fast cooling, pearlite growth kinetics was calculated with self-developed diffusion coefficients of elements in grain boundary. Overaging temperature was determined through the calculation of T0 temperature by both equilibrium and para-equilibrium assumptions, which was different from the current determination, which is only based on an equilibrium estimation.LI Lin DE COOMAN B C LIU Ren-dong VLEUGELS j ZHANG Mei SHI Wen 2007Journal of Iron and Steel Research(International)2007,14,6:13

3放电等离子烧结添加TiC开孔钛基复合材料的磨损模式(英文)显示文摘采用放电等离子烧结法制备具有开孔隙的钛基复合材料(TMCs),研究添加TiC增强颗粒对材料摩擦性能的影响。材料中含有同等摩尔比的Ti和TiH2以及不同体积分数的TiC(0、3%、10%和30%),烧结温度为850℃。采用纳米压痕和磨损试验评估材料的纳米硬度和耐磨性能,摩擦试验采用球-平面接触往复滑动模式。结果显示,随着TiC含量的增加,材料的纳米硬度从5 GPa增加到14 GPa。当TiC含量为10%时,材料的摩擦因数最低(0.2),磨损率也最低。当TiC含量较低时,样品发生粘着磨损,并伴随严重的塑性变形;当TiC含量适中时,样品表面形成机械混合层(MML);当TiC含量较高时,样品的主要磨损机制为磨粒磨损。总之,随着TiC含量的变化,材料的磨损机制、摩擦因数和磨损量也随之变化。I.

4系统性药物治疗儿童银屑病的安全性显示文摘银屑病是一种常见的慢性炎症性皮肤病。成年人的发病率为2%~3%,其中大约有三分之一的患者在18岁之前发病。在儿童期,该病的发病率呈线性增长。从1970年至2000年,儿童银屑病的发病率增加了一倍多。尽管对许多轻度银屑病患儿而言,局部治疗已足够,但对更多可能影响生活质量的重度或顽固性的银屑病患儿,则往往需要系统性治疗。bronckers imgj seyger mmb west dp lara-corrales i tollefson m tom wl hogeling m belazarian l zachariae c mahé e siegfried e philipp s szalai z vleugels ra holland k murphy r baselga e cordoro k lambert j alexopoulos a mrowietz u kievit w paller as 邓婕(编译) 张锡宝(审校) 2017皮肤性病诊疗学杂志2017,24,5:3
5烧结温度和添加碳化物对NbC-Ni基金属陶瓷显微组织和力学性能的影响显示文摘本文报道了烧结温度和添加碳化物(VC、Mo_2C和TiC)以及Mo金属对一种新型NbC-Ni基金属陶瓷的致密化、NbC晶粒生长、显微组织演变以及维氏硬度(HV30)和断裂韧性的影响。所有的金属陶瓷均采用真空无压烧结制备,使用电子探针显微分析(EPMA)以及X射线衍射(XRD)来分析试样的微观组织、相组成及晶格常数的变化。结果表明,烧结温度,特别是添加碳化物的含量对NbC-Ni金属陶瓷的性能有显著的影响。当烧结温度低于1 340°C时,试样内存在Ni池和残余孔隙。温度高于1 380℃时,添加VC或Mo/Mo_2C的NbC-Ni基金属陶瓷达到完全致密,呈现出类似于WC-Co的两相组织结构。同时添加TiC+VC或TiC+Mo_2C的材料则形成一种含有芯环结构的NbC晶粒。相对于无添加的NbC-Ni金属陶瓷,添加体积分数5%~10%VC/Mo_2C和10%TiC能够明显提高材料的硬度和断裂韧性。黄水根 Vleugels Jozef Cannizza Eduardo Woydt Mathias 刘中柱 Mohrbacher Hardy 2018硬质合金2018,35,2:2
6以MH_2(M=Ti,Zr)为原料反应烧结制备MB_2-SiC复相陶瓷显示文摘分别以TiH2,ZrH2为原料,结合原位反应与脉冲电流辅助烧结制备了TiB2-SiC及ZrB2-SiC复相陶瓷。研究发现,所制备的复相陶瓷表现出一定的织构化现象,TiB2及ZrB2晶粒在反应烧结过程中其(001)面沿垂直压力和电流方向生长。金属氢化物粉体的粒径大小对复相陶瓷的致密化及微结构有较大影响:粒径越小越有利于陶瓷的致密化和硼化物晶粒的定向生长。由于金属硼化物的定向,复相陶瓷的机械性能表现出各向异性。TiB2-SiC复相陶瓷具有较高的断裂韧性,最高可达7.3 MPa.m1/2,而ZrB2-SiC复相陶瓷具有更高的抗弯强度(937 MPa)。冉松林 汪德文 Huang Shui-gen Van der Biest Omer Vleugels Jef 2013人工晶体学报2013,42,4:2
7Computer simulation of W-C-Co-V system diffusion couples显示文摘Diffusion couples,WC/Co-1at.%C,V8C7/Co,and WC/Co-0.3wt.%V8C7 were constructed and annealed at tem-peratures ranging from 1100 to 1300°C. The concentration profile of V and W atoms in these couples were measured by EPMA. Aided by Thermo-calc & DICTRA software package,the concentration profiles of W and V in established diffu-sion couples were calculated by the moving boundary model according to revised dynamic parameters and MOB database,respectively. Then the concentration profile of W in Co binder during sintering WC-Co cemented carbide was simulated by the Cell model. It can provide reference for composition and sintering process design of cemented carbides with high per-formance. Meanwhile,the validity of revised dynamic parameters of the W-C-Co-V system is verified by the comparison of experimental and simulated results.HE Yanlin LI Lin HUANG Shuigen Jef Vleugels Omer Van der Biest 2007Rare Metals2007,26,5:2
