The effects of strain rate and temperature on the induced transformation behaviour retained austenite hence mechanical properties TRIP-aided steels with annealed martensite (AM), bainitic ferrite (BF) polygonal (PF) matrix microstructures were examined. For this, tensile tests carried out at four different rates varying from 3.33×10−5 s−1 to 3.33×10−2 room 150°C. Additional intermittent intermediate estimate extent using X-ray diffraction analysis. Tensile strength (TS) decreased both...
Abstract The thermomechanical behavior of fluorinated and oxyfluorinated Kevlar fiber‐reinforced ethylene propylene (EP) composites has been studied. have prepared using brabender mixer are cured compression molding technique. FTIR study performed to understand the chemical reaction occurred due modification composites. Thermal crystallinity studied by DSC, TGA, DMTA, XRD. These studies show that thermal stability, storage modulus, as well treated EP increases in comparison untreated...
Abstract This article deals with oxy-fluorinated short KevlarTM fiber reinforcement and its effect on the dynamic, mechanical, rheological properties of syndiotactic polystyrene composites. The composites were prepared using a twin-screw extruder at 20 rpm resulting composite was molded under injection molding. study shows that addition into matrix significantly affects dynamic mechanical by appreciably increasing storage modulus. Rheological reveal significant enhancement viscosity treated...
Artificial neural networks are parameterized nonlinear models used for empirical regression and classification modelling. Their flexibility enables them to discover very complex relationships among large number of variables with interdependencies. Hence it is a appropriate technique developing predictive in the short term. This article discusses development network based on Bayesian framework some applications same. These examples include: (i) prediction yield tensile strengths hot-rolled...
Low alloy transformation induced plasticity (TRIP)-aided steels are of particular interest to the automotive industry as they offer an excellent combination strength and ductility at affordable costs. These unique properties depend primarily on deformation behavior retained austenite martensite, which is therefore, most important aspect TRIP-aided steels. As such, it develop a mathematical model for austenite. This would not only help in better understanding but also aid design...
Abstract A phenomena based description of the microstructure and flow stress evolution metals subjected to hot working is presented. The change in dislocation density with time was determined from generation recovery rates. Dynamic recrystallization assumed initiate when became greater than a critical value. calculated as function overall deformed recrystallized grains. To validate model set single hit compression tests were carried out on two different AFP (Ausscheidungshärtende...
Abstract Binary blends of a reactive ketone based polymer with liquid crystalline (LCPA‐950) were studied. The main properties required are flexibility and thermal resistance material in presence polyphosphazene, which acts as compatibilizer. It has been observed that the addition LCP composites showed reduced viscosity during blending changes crystallization phase. FTIR study there was partial interaction between PEEK polyphosphazene. Polyphosphazene is miscible both LCP, evident from DMA...
A neural network model has been developed to predict the strain induced transformation behaviour of retained austenite in plasticity aided steels, as a function driving force for martensitic transformation, initial content, matrix microstructure and forming conditions. The was found make realistic predictions that generally agree with established metallurgical principles other published data.
