作者： chun-sen liu Zhengzhou University of Light Industry Henan Provincial Key Lab of Surface & Interface Science

Metal-organic frameworks(MOFs) are a unique class of hybrid porous solids with metals and *** to traditional porous materials, they possess predominance of large surface areas,tunable pore size and shape, adjustable composition and functionalized pore surface, which enable themunique advantages and promises for applications in many areas including chemical separation, gas storage,catalysis, drug delivery and optical sensing/detection. Our group has focused on the construction of MOFs based on the tritopic carboxylic and bifunctional ligands with targeted pore shapes andenvironments. Their potential applications to sorption,sensing, luminescence, and electrochemistry were explored.

Hot compression tests were carried out with specimens of 20Cr-24Ni-6Mo super-austenitic stainless steel at strain rate from 0.01 to 10 s^-1 in the temperature range from 950 to 1150 ℃,and flow behavior was *** analysis indicated that dynamic recrystallization（DRX）behavior was more sensitive to the temperature than strain rate,and full DRX was obtained when the specimen deformed at 1150℃.When the temperature reduced to 1050 ℃,full DRX was completed at the highest strain rate 10 s-l rather than at the lowest strain rate 0.01 s-1 because the adiabatic heating was pronounced at higher strain *** addition,flow behavior reflected in flow curves was inconsistent with the actual microstructural evolution during hot deformation,especially at higher strain rates and lower ***,flow curves were revised in consideration of the effects of adiabatic heating and friction during hot *** results showed that adiabatic heating became greater with the increase of strain level,strain rate and the decrease of temperature,while the frictional effect cannot be neglected at high strain ***,based on the revised flow curves,strain-dependent constitutive modeling was developed and verified by comparing the predicted data with the experimental data and the modified *** result suggested that the developed constitutive modeling can more adequately predict the flow behavior reflected by corrected flow curves than that reflected by experimental flow curves,even though some difference existed at 950℃ and 0.01 s^-*** main reason was that plenty of precipitates generated at this deformation condition and affected the DRX behavior and deformation behavior,eventually resulted in dramatic increase of deformation resistance.
