Die corrosion has been a concern during aluminum alloy die casting. The casting parameters play significant role in causing corrosion, such as the temperature of melt and working time. In order to study effect time on dynamic behaviors, SDHA steel was stirred molten ADC12 at 650–800 °C. morphology product were investigated through X-ray diffraction (XRD) scanning electron microscope (SEM) obser...

Based on the 3 factors and levels orthogonal experiment method, compositional effects of Mg, Si, Ti addition microstructures, tensile properties, fracture behaviors high-pressure die-casting Al-xMg-ySi-zTi alloys have been investigated. The analysis variance shows that both Mg Si apparently influence properties alloys, while does not. mechanical are comprehensively influenced by amount eutectic...

introduction: many studies have been performed to evaluate the stress distribution around endodontic posts; those which compared posts composed of different materials are rare. the aim of this study was to compare stresses induced in dentin by three structurally different posts using photoelasticity method. materials and methods: nine blocks of psm-5 photoelastic material with 45×45×10 mm dimen...
