Lightweighting in the transportation industry is today recognized as one of most important strategies to improve fuel efficiency and reduce anthropogenic climate-changing, environment-damaging, human death-causing emissions. However, structural applications lightweight alloys are often limited by some inherent deficiencies such low stiffness, high wear rate inferior strength. These properties could be effectively enhanced addition stronger stiffer reinforcements, especially nano-sized...
Aluminum (Al) alloys are increasingly used in the transportation industry to reduce weight of vehicles due their high strength-to-weight ratio. These applications unavoidably involve similar and dissimilar joining an automotive grade 5754 Al alloy manufacture multi-material vehicle body structures parts. Ultrasonic spot welding (USW), emerging promising solid-state technology, can be suitably applied join alloys. In this study, was welded (Al5754-Al5754) (Al5754-ZEK100 Mg alloy, Al5754-HSLA...
The creep behavior of 8xxx aluminum conductor alloys with different quantities Fe-rich particles and solutes was investigated. Creep resistance significantly improved large amounts solutes. At 100 °C, a high Fe solute content (0.023 wt.%) had stronger effect on than FeAl 3 particles. However, as the temperature increased to 150 200 amount (2.5 vol.%) stronger. threshold stress increasing particle contents, each factor being independent, but it decreased temperature. true exponents were...
The present work encompasses the effect of overaging on strain-controlled low-cycle fatigue (LCF) behavior an extruded AA6061 aluminum alloy at varying strain amplitudes. During T7 aging treatment, size precipitates increased from 60 nm under T6 conditions to 220 after for 48 h 200 °C, leading a decrease in monotonic tensile strength. LCF tests, nearly symmetrical hysteresis loops can be observed mid-life cycle all test conditions, whereas first-cycle were moderately inflected long-aging...
Composites with polypropylene (PP) and lyocell fibers were manufactured by compression molding technique. In order to improve the interfacial adhesion between natural thermoplastic matrix during manufacturing, maleic anhydride grafted (MAPP) as a coupling agent has been employed. Physical properties such void contents water absorption rate studied. Tensile flexural tests carried out evaluate composite mechanical properties. test results showed higher strength modulus of than pure (PP)....
This research explores micromechanics modeling for the prediction of stiffness and strength properties nanocomposites consisting randomly oriented carbon nanotubes (CNTs) an epoxy matrix, multiscale composites unidirectional glass fibers, orientated CNTs, matrix.For properties, including Young's modulus, Poisson's ratio, shear CNTs/epoxy fiber/CNTs/epoxy composites, Mori-Tanaka model Halpin-Tsai equations were used.To obtain tensile compressive strength, several empirical employed.The...
Cyclic deformation characteristics of a rare-earth (RE) element containing extruded Mg-10Gd-3Y-0.5Zr (GW103K) magnesium alloy were evaluated via strain-controlled low-cycle fatigue tests under varying strain amplitudes. Microstructural observations revealed that this consisted fine equiaxed grains and large number RE-containing precipitates. Unlike the RE-free alloys, exhibited essentially cyclic stabilization symmetrical hysteresis loop due to relatively weak crystallographic textures...
Composites with polypropylene (PP) and 2 wt% NaOH treated jute fibers were prepared by the injection molding technique.In order to improve affinity adhesion between reinforced fiber polymer matrix (polypropylene) during manufacturing, maleic anhydride grafted (MAPP) as a coupling agent has been employed.Tensile tests carried out evaluate composite mechanical properties.The tensile test results showed have higher strength modulus than pure (PP).In addition, found be influenced variation of...
