Mechanical Characterization of Ceramic Nano B₄C- Al2618 Alloy Composites Synthesized by Semi Solid State Processing

Three-Dimensional Finite Element Numerical Simulation and Analysis of Solid-State Processing of Metal Material

“…e alloy ingot with the structure is heated and sheared during the transportation process through a heating source and a special spiral propulsion system so that it has importance and is injected into the mold cavity to form injection molding which is essentially a kind of rheological technology. As shown in Figure 7, in stage (1), wall thickness changes everywhere are not gradually and slowly, and the change at the beginning quickly reaches the final change result; in stage (2), the bending part of the tube gradually moves to the rear end of the tube as the bending angle increases; in stage (3), the wall thickness is still the initial value; as the bending angle increases, the deformation zone moves to this point; in stage (4), tensile and compressive stresses are generated on the pipe wall, resulting in a change in the wall thickness; in stage (5), no bending deformation occurs, and the wall thickness at this time remains basically unchanged; in stage (6), the inner concave edge of the elbow is compressed to increase the wall thickness, while the outer convex edge is stretched to reduce the wall thickness. e total change of the equivalent stress value during the bending deformation process of the pipe fitting increases with the increase of the bending angle, and the stress value of the inner concave side pipe wall of the curved pipe fitting is larger than that of the outer convex side pipe wall.…”

“…Applying three-dimensional (3D) finite element numerical method to the simulation of solid-state processing can perform analysis of metal material's forging processes before production trial production, can obtain their relevant information such as material flow law, temperature field, and strain field under the minimum physical test conditions, and thereby predicting metal material's forming defects and improving their forging quality [5].…”

Investigations on Mechanical Behaviour of Micro B4C Particles Reinforced Al6061 Alloy Metal Composites

“…The elongation of as cast Al6061 alloy is 6.69%, this is decreased to 1.5% with the addition of 12 weight % of hard ceramic particles. The strong bonding between the particle and matrix material enhances the strength meanwhile decreases the ductility due to formation of high stress concentration around the particles (17,18) .…”

Mechanical characterization and fractography of 100 micron sized silicon carbide particles reinforced Al6061 alloy composites

“…An optimized two stage stir casting technique is developed for the composite preparation. Prepared aluminum-silicon carbide, alumina, and graphite composites are evaluated for their physical, mechanical, and wear properties [5]. Manish et al [6] reviewed the mechanical behaviour of various metal matrix composites reinforced with Al2O3, B4C, TiC, graphite, SiC, and TiB2 particles.…”

“…Fig.7is the graph of UTS and YS (stress to produce a plastic strain 0.2%) of the Al composites, plotted with the weight percentages of SiC content. The test found that the ultimate and yield strength of base Al6061 alloy is 141 MPa and 126 5. MPa, respectively.…”
