Interstitial free (IF) steels are characterized by their interstitial ferritic matrix due to addition of micro-alloying elements that draw carbon and nitrogen out form carbonitrides. The IF typically have excellent deep drawing ability, certain mechanical strength, high plastic deformation performance. In this paper, the microstructure evolution carbides precipitation behavior during hot rolling, cold rolling annealing processes been studied using both experimental thermodynamic kinetic...
Abstract Linear polypropylene (PP) foams, blown in the continuous extrusion process using supercritical CO 2 as blowing agent, exhibited poor cell morphology and narrow foaming window, because of their low melt strength. In this study, polytetrafluoroethylene (PTFE) was blended with PP resin aim improving behavior PP. It found that PTFE particles were deformed into fine fibers under shear or extensional flows during process, which significantly increased strength from 0.005 N to 0.03...
ABSTRACT The fabrication of high‐performance oil sorbents is great significance for spill cleanup. main objective this study was to prepare open‐cell polypropylene/polyolefin elastomer (PP/POE) blend foams reusable sorption. Open‐cell PP/POE were prepared via continuous‐extrusion foaming using supercritical carbon dioxide as the blowing agent. interconnected structure characterized by scanning electron microscopy. hydrophobicity and lipophilicity revealed tests contact‐angle measurement,...
Abstract Natural structure‐forming processes found in biological systems are fantastic and perform at ambient temperatures, contrast with anthropogenic technologies that commonly require harsh conditions. A new research direction “bioprocess‐inspired fabrication” is proposed to develop novel fabrication techniques for advanced materials. Enamel, an organic–inorganic composite biomaterial outstanding mechanical performance durability, formed by repeating the basic blocks consisting of...
The present study investigated the effects of austempering process far below Ms (martensite start temperature) on microstructural evolution and impact toughness bainitic steel with ultrahigh compared results tempered martensitic steel. revealed that lamellar composed ferrite laths retained austenite films is obtained by temperature. exhibited Charpy V-notch absorbed energy up to 131 ± 6 J, which was 2.7 times higher than (49 1 J). ultra-high attributed deflection crack propagation direction...
In this study, the multi-scale microstructures of bainitic steel were refined to different degrees by austempering below Ms (martensite start temperature). The influence and their boundaries on impact toughness was analyzed. results revealed that significantly improved as temperature decreased. block structure Bain groups are Ms, thereby introducing high-density HAGBs (high-angle grain boundaries) increasing crack propagation resistance. proportion V2, V3, V5 variants increased formed with...
Background After the successful reforms of drug pricing, China has implemented two significant to reduce medical consumables expenses: elimination markup on prices (zero-markup policy) and implementation centralized procurement high-value (national policy). The public hospitals in Guangdong province had zero-markup policy national for coronary stents. Currently, research consumable stents at hospital level lacks analysis changes cost structures (other expenses) studies response strategies....
