ABSTRACT A hydrophobically associating copolymer was prepared by free‐radical polymerization with acrylamide (AM), acrylic acid (AA), and N ‐allyloctadec‐9‐enamide (NAE) as monomers. The structure characterized Fourier transform infrared spectroscopy, 1 H‐NMR, 13 C‐NMR, scanning electron microscopy. rheological experiments indicated that the possessed superior properties compared partially hydrolyzed polyacryamide. It found an AM/AA/NAE/Tween‐80 system could effectively decrease interfacial...
Continuous cooling transformation (CCT) diagrams represent roadmaps for producing all heat-treatable steels. CCT curves provide valuable information on the solid-state phase sequence, depending defined strategies, alloying concept of steel and previous processing steps. The experimental characterization is usually done a laboratory scale applying thermal analysis dilatometry. In current research studies, however, also other in-situ methods such as high-temperature laser scanning confocal...
The effects of partitioning temperature and time on the strengthening plasticising mechanism a one-step quenching (Q&P) steel were investigated. results show that as decreased, lath martensite became finer with higher dislocation density, while density RA amount decreased increasing time. Lower shorter are conducive to achieve high ultimate tensile strength 1377 MPa better total elongation 12.3% for low-carbon Q&P steels. Meanwhile, caused by solid solution main mechanisms In addition, new...
Most carbonitride solubility products of Ti do not consider the influence commonly contained alloying elements such as Mn and Si in predicting dissolution law carbonitrides steels, which would cause a deviation between experimental data predicted values. To solve this problem, product models TiN TiC austenite considering Mn, Mo, Cr, Si, Al are established present study based on two‐sublattice model relevant thermodynamic data. Different austenitizing temperatures designed to analyze...
Abstract Based on the fluid motion equation, finite element equation of dam-reservoir water coupling system was established to calculate dynamic response between compressible reservoir and face rockfill dam, compared with calculated by Westergaard added mass formula, incompressible calculation results were discussed. The show that failure panel tensile stress exceed standard will affect overall anti-seepage safety basin. Although formula has little effect absolute acceleration maximum...
A novel method of cryorolling martensite for fabricating ultrafine grained low-carbon steel with attractive strength was proposed. The results indicate that ultrafine-grain structured could be manufactured by and the subsequent annealing martensite. mean ferrite size 132.0 nm tensile 978.1 MPa were obtained in a specimen reduction 70% thickness. There peak value valley grain increase from 50% to 80%, respectively. further growth at 80% is attributed heavier distortion energy large reduction,...
Ultrafine grained low‐carbon steels are fabricated by cryorolling and cold‐rolling martensite starting microstructure at liquid nitrogen temperature ambient temperature, respectively. The results indicate that process present more potential in refining ferrite grains steel (132 nm) than deformation (330 nm). tensile strength increase from 867.0 to 970.2 MPa for the specimen cryorolled compared rolled temperature. decreased elongation is attributed coarse Fe 3 C particles during annealing....
Decellularized matrix from porcine small intestinal submucosa (SIS) endows scaffolds with an ECM-like surface, which enhances stem cell self-renewal, proliferation, and differentiation. Mesoporous bioactive glass (MBG) is extensively recognized as excellent bio-ceramic for fabricating bone grafts.In the current study, SIS was doped on MBG scaffold (MBG/SIS) using polyurethane foam templating polydopamine chemistry method. To mimic bony environment of a natural matrix, ECM-inspired delivery...
Ideal bone tissue engineering scaffolds composed of extracellular matrix (ECM) require excellent osteoconductive ability to imitate the environment. We developed a mineralised tissue-derived ECM-modified true ceramic (TBC) scaffold for delivery aspartic acid-modified morphogenic protein-2 (BMP-2) peptide (P28) and assessed its osteogenic capacity. Decellularized ECM from porcine small intestinal submucosa (SIS) was coated onto surface TBC, followed by mineralisation modification (mSIS/TBC)....
Previous studies on the austenite grain growth were mostly based a fixed temperature, and relationship between austenitizing parameters was fitted according to results. However, there is lack of quantitative research during heating process. In present work, diffusion principle controlled Ti microalloying element, process carbonitrides containing analyzed. Combined with precipitation model model, prediction microalloyed steel different heat treatment processes established. The size versus...
