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

4Sol-gel derived HA/TiO_2 double coatings on Ti scaffolds for orthopaedic applications显示文摘Hydroxyapatite/titania (HA/TiO2) double layers were coated onto Ti scaffolds throughout for orthopaedic applications by sol-gel method. Differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and X-ray diffractometry (XRD) were used for the characterisation of the phase transformations of the dried gels and coated surface structures. Scanning electron microscope (SEM) equipped with energy dispersive spectrometry (EDS) was used for the observation and evaluation of the morphology and phases of the surface layers and for the assessment of the in vitro tests. The in vitro assessments were performed by soaking the HA/TiO2 double coated samples into the simulated body fluid (SBF) for various periods. The TiO2 dipping-coating method at a speed of 12 cm/min, followed by a heat treatment at 600 ℃ for 20 min. The HA la lyaeyre wr wasa ssu cbosaetqeude bnytl ya dipping-coated on the outer surface at the same speed and then heat-treated at difference temperatures. The results indicat that the HA phase begins to crystallize after a heat treatment at 560 ℃. The crystallinity increases obviously at 760 ℃. SEM observations find no delamination or crack at the interfaces of HA/TiO2 and TiO2/Ti. The HA/TiO2 coated Ti scaffolds displays excellent bone-like apatite forming ability when it is soaked into SBF. Ti scaffolds after HA/TiO2 double coatings can be anticipated as promising implant materials for orthopaedicXU W HU W Y LI M H MA Q Q P. D. HODGSON WEN C E 2006中国有色金属学会会刊:英文版2006,16,B01:5
5Environmental and Psycho-social Factors Related to Prostate Cancer Risk in the Chinese Population:a Case-control Study显示文摘Objective To study the risk environmental and psycho-social factors associated to prostate cancer(PCa) in Chinese population. Methods 250 PCa patients and 500 controls were enrolled in this case-control study. Information was collected and logistic regression analysis was used to estimate the odds ratios(OR) and 95% confidence intervals(95% CI) for relationship between lifestyle, eating habits and psycho-social factors with PCa risk. Results Green vegetables and green tea were associated with a decreased risk of PCa(OR=0.39, 95% CI: 0.28-0.53; OR=0.59, 95% CI: 0.40-0.87, respectively). Family history of PCa(OR=7.16, 95% CI: 2.01-25.49), history of prostate diseases(OR=2.28, 95% CI: 1.53-3.41), alcohol consumption(OR=1.97, 95% CI: 1.33-2.90), red meat consumption(OR=1.74, 95% CI: 1.20-2.52), barbecued(OR=2.29, 95% CI: 1.11-4.73) or fried(OR=2.35, 95% CI: 1.24-4.43) foods were related with increased PCa risk. Negative psycho-social factors including occupational setbacks(OR=1.61, 95% CI: 1.00-2.59), marital separation(OR=1.94, 95% CI: 1.29-2.91), self-contained suffering(OR=2.37, 95% CI: 1.58-3.55), and high sensitivity to the personal comments(OR=1.73, 95% CI: 1.18-2.54) were related to PCa. Conclusion Regular consumption of green vegetables and green tea may suggest protective effects on PCa. Alcohol consumption, red meat consumption and barbecued or fried foods were associated with PCa. Negative psycho-social factors may also play a role in the incidence of PCa in Chinese population.LI Mei Ling LIN Ji HOU Jian Guo XU Lei CUI Xin Gang XU Xing Xing YU Yong Wei HAN Xue WANG Guo Min GUO Jian Ming XU Dan Feng THOMPSON Timothy C CAO Guang Wen ZHANG Hong Wei 2014Biomedical and Environmental Sciences2014,27,9:5
6Thermal Stability of Retained Austenite in TRIP Steel After Different Treatments显示文摘Thermal decomposition of retained austenite in TRIP steel was investigated by means of differential scanning calorimetry(DSC).The decomposition curve was abnormal,and the decomposition temperature and the activation energy were measured by the Kissinger method,which were all higher than those in quenched steel.The thermal decomposition data of samples soaked in liquid nitrogen after TRIP treatment were all similar to those without additional low temperature treatment.It indicated that there is a high thermal stability in retained austenite of the TRIP steel at low temperature,which was also proved by XRD analysis.SHI Wen LI Lin Bruno C De Cooman Patrick Wollants YANG Chun-xia 2008Journal of Iron and Steel Research(International)2008,15,1:5

8Biosynthesis of Unsaturated Fatty Acids via Mortierella Isabellina Cultivated in a Medium Containing Butanol显示文摘Mortierella isabellina was found to accumulate large amounts of unsaturated fatty acids when it was grown in a medium containing butanol(5 g/L) and yeast extract(10 g/L) and cultivated at 25 ℃ for 5 d during which additional feeding butanol of 2 g/L was fed after being cultivated for 48 h . The resultant mycelial lipids accounted for 40 1% of the dry mycelia, while about 34% of butanol in the medium was converted. The mycelial lipids contained four kinds of unsaturated fatty acids, i.e ., palmitoleic(4 9%), oleic(54 1%), linoleic(10 4%) and linolenic(5 4%) acids. Those accounted for 74 8% of the total fatty acids. The effects of the culture conditions, such as cultivation temperature, initial pH of the medium and additional feeding butanol in the course of cultivation, on the production of mycelial lipids by M. isabellina were studied.XIAN Mo 1, YAN Ji chang 2, CHENG Tie xin 1, KANG Yi jian 3, LI Wen xing 1, BI Ying li 1 and ZHEN Kai ji 1** 1.
