New-emerging approach for fabrication of near net shape aluminum matrix composites/nanocomposites: Ultrasonic additive manufacturing
Recently, high-performance lightweight materials with outstanding mechanical properties have opened up their way to some sophisticated industrial applications. As one of these systems, aluminum matrix composites/nanocomposites (AMCs) offer an outstanding combination of relative density, hardness, wear resistance, and mechanical strength. Until now, several additive manufacturing methods have be...
متن کاملUltrasonic Inspection of Near Net Shape Disks
With new fabrication technologies, disks for gas turbine engines can be manufactured from high strength ~terials with a substantial cost savings. Utilization of these technologies to their full potential is currently limited by the ability to perform a reliable high resolution, high sensitivity ultrasonic inspection. A computer automated inspection system is being developed to inspect near-net ...
متن کاملdesign of the die profile for the incremental radial forging process
in this paper, based on the slab method of analysis, a novel and general approach isdeveloped for studying the radial forging process with curved profile dies. the presented approachis not only more general with respect to previous studies, but it is also easier to understand and useand can be efficiently used for optimization of the die profile depending on the forging geometryand conditions. ...
متن کاملProcess modeling of microalloyed steel for near net shape casting
Strip casting is an emerging technology for flat products; it is based on the concept of near-net shape casting; it holds potential for substantial energy saving and reduction in environmentally undesirable emission. In conventional thermo-mechanical processing, the pinning pressure due to the effects of Nb and NbC on boundary mobility is used to advantage to retard static recrystallisation and...
متن کاملClose-die Flashless Forging in Automotive Industry
This paper describes the possibilities and conditions of the closed-die flashless forging process using conventional mechanical presses and equipment. The technique of driven gear forging with an internal flash or with special die design has been developed. The quality of forgings is comparable to that achievable on Hatebur presses. Furthermore the problem of how to increase shift production un...
