Investigation of Parameters Involved in the Production of Aluminum Matrix Composites Using Hot Powder Extrusion
Aluminum matrix composites reinforced with Al2O3 and SiC particles (5 Vol%) were produced using the hot powder extrusion method. Extrusion temperature and extrusion reduction in area were chosen in the range of 500 to 600°C and 90 to 95%, respectively. The physical and mechanical properties of the extruded composites such as density, tensile strength, elongation and microhardness were evaluated...

متن کاملOn the Study of Mechanical Properties of Aluminum/Nano-Alumina Composites Produced via Powder Injection Molding
Powder Injection Molding (PIM) is a precision manufacturing process used for production of advanced composites. Mixing of polymeric binder with metal powders, molding of feedstock, de-binding of brown parts and sintering of green samples are four main steps of this process. In the present study, the compounds containing multi-component binder system and aluminum/ nano-alumina (0-9 wt.%) powders...
متن کاملNeural Modeling of Parison Extrusion in Extrusion Blow Molding
Back-propagation (BP) neural network is used to develop process models for the parison extrusion in extrusion blow molding based on experimental data. In applying the BP network, some modifications, such as using a self-adaptive learning rate coefficient, determining the number of hidden neurons through experimentation, and so on, to the original BP algorithm are carried out to speed up learnin...
متن کاملCreep of aluminum syntactic foams
Aluminum syntactic foams with densities of 1.2–1.5 g/cm3 were deformed at 500 ◦C under constant uniaxial compressive stresses ranging from to 14 MPa. The foam creep behavior is characterized by a short primary stage and a long secondary stage where the strain rate is constant and inimum, followed by a tertiary stage at high stresses. The minimum strain rate varies with stress according to an ap...
