RISOn tool–workpiece interactions during machining metal matrix composites: investigation of the effect of cutting speed
Metal matrix composites (MMCs) are widely employed in many industrial applications due to their excellent strength and wear characteristics. In order to overcome the challenges faced during machining MMCs, knowledge regarding machinability of MMCs...
On modeling the deformations and tool-workpiece interactions during machining metal matrix composites
Significance of application of metal matrix composites (MMCs) in various industries has already been demonstrated. In order to address the challenges faced during machining MMCs, development of novel modeling techniques for understanding...
Incorporating Aspect Ratio in a New Modeling Approach for Strengthening of MMCs and its Extension from Micro to Nano Scale
is developed in this paper incorporating the aspect ratio effect into the geometrically necessary dislocation strengthening relationships. By making use of this multi-scale approach, the deformation behavior of metal–matrix composites (MMCs) and metal...
Evaluation of Characteristics of Interfacial Phases Produced in Al/Ni3Al Composite during Manufacturing
Metal matrix composites (MMCs) are currently being investigated because of their superior properties. The properties are mainly attributed to the efficiency of the load transfer from the matrix to the reinforcements through the ma...
In-situ fabrication of Al(Zn)-Al2O3 graded composite using aluminothermic reaction during hot pressing
In this study, fabrication of multilayer Al(Zn)-Al2O3 with different volume fractions of Al2O3 were investigated. In this regard, Al and ZnO powders were milled by a planetary ball mill and then five-layer functionally ...
Ni–Cr matrix composites reinforced with nano- and micron-sized surface-modified zirconia: Synthesis, microstructure and mechanical properties
Ni-20Cr alloy with Ni-coated and uncoated hybrid particle size (nano- and micron) ZrO2 reinforcements (11, 15 and 19 wt. %) were used to prepare oxide dispersion strengthening (ODS) superalloy by powder metallurgy. The ...
