Roller Burnishing of Particle Reinforced Aluminium Matrix Composites
Energy and resource efficient systems often demand the use of light-weight materials with a specific combination of properties. However, these requirements usually cannot be achieved with homogeneous materials. Consequently, composites enabling tailored properties gain more and more importance. A special kind of these materials is aluminium matrix composites (AMCs), which offer elevated strengt...
متن کاملTENSILE AND FRACTURE CHARACTERISTICS OF A SIC- PARTICLE-REINFORCED 7075 ALUMINIUM ALLOY
Fracture behavior of a 7075 aluminium alloy reinforced with 15 Vol%. SiC particles was studied after T6 and annealing heat treatments under uniaxial tensile loading at room temperature. The scanning electron microscopy of fractured surfaces and EDS analysis showed:, that fracture mechanism changed from due mainly to fractured particle in T6 condition to interface decohesion in samples in anneal...
متن کاملStrengthening Mechanisms in the Aged 2024 and 7075 Aluminium Alloys
Aluminum 2024 and 7075 alloys which are widely used in aerospace and marine applications were chosen to investigate their strengthening mechanisms. Using differential thermal analysis (DIA), metallography and tension tests, the best solutionizing conditions were determined to be 500±5°C and 2 hours for 2024 and 480?±5°C and 1 hour for 7075 alloy. Aging was performed in the range of 100 to 200°C...
متن کاملStrain gradient effects on deformation strengthening behavior of particle reinforced metal matrix composites
Dislocation models with considering the mismatch of elastic modulus between matrix and reinforcing particles are used to determine the effective strain gradient h for particle reinforced metal matrix composites (MMCp) in the present research. Based on Taylor relation and the kinetics of dislocation multiplication, glide and annihilation, a strain gradient dependent constitutive equation is deve...
متن کاملStrengthening of Fiber-reinforced Self-healing Ceramics
ID No: FC-169 ABSTRACT The continuous fiber reinforced self-healing ceramic composites (shFRC) were proposed as one of the candidate materials for turbine blade [1]. The shFRC consists of three components, which are oxide fiber bundle, oxide matrix and self-healing agent interlayer. As the self-healing is generated at only the interlayer, it is necessary that crack propagation is led into the i...
