RISPhysics Based Microstructure Simulation for Drilled Hole Surface in Hardened Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For a fully hardened steel material, hole surface microstructures are often subject to microstructural transition because of the intense thermomechanical loading. A white layer can be formed on the surface of a drilled ...
Dislocation Density Based Grain Refinement Modeling of Orthogonal Cutting of Titanium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, orthogonal cutting has been exploited as a means for producing ultrafine grained (UFG) and nanocrystalline microstructures for various metal materials, such as aluminum alloys, copper, stainless steel, titanium ...
Experimental Investigation and Numerical Analysis of Mechanical Ruling for an Aluminum-Coated Diffraction Grating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanical ruling process using a diamond tool is an important method for fabrication of low-density diffraction gratings. In mechanical ruling, a deposited film of aluminum or gold is mechanically burnished by the ...
Preliminary Experimental Study of Warm Ultrasonic Impact-Assisted Laser Metal Deposition
