Thermodynamics of densification of powder compact
This paper established a necessary condition for the sintering of powder compacts by examining the total free energy balance in terms of the particle size, neck size and contact number. The thermodynamic analysis of the proposed model clarifies the relation of shrinkage (q) of powder compact-contact angle (f)-relative density at a given dihedral angle (fe) of a grain boundary. Faster densificat...
متن کاملFabrication, densification, and replica molding of 3D carbon nanotube microstructures.
The introduction of new materials and processes to microfabrication has, in large part, enabled many important advances in microsystems, lab-on-a-chip devices, and their applications. In particular, capabilities for cost-effective fabrication of polymer microstructures were transformed by the advent of soft lithography and other micromolding techniques (1, 2), and this led a revolution in appl...
متن کاملProgress in Titanium Metal Powder Injection Molding
Metal powder injection molding is a shaping technology that has achieved solid scientific underpinnings. It is from this science base that recent progress has occurred in titanium powder injection molding. Much of the progress awaited development of the required particles with specific characteristics of particle size, particle shape, and purity. The production of titanium components by injecti...
متن کاملCompact Model Representation for 3D Reconstruction
3D reconstruction from 2D images is a central problem in computer vision. Recent works have been focusing on reconstruction directly from a single image. It is well known however that only one image cannot provide enough information for such a reconstruction. A prior knowledge that has been entertained are 3D CAD models due to its online ubiquity. A fundamental question is how to compactly repr...
متن کاملMicro-powder injection molding: Investigation of powder-binder separation using synchrotron-based micro-tomography and 3D image analysis
Micro-powder injection molding (μ-PIM) is one of the most promising processes of mass production for the fabrication of small complexly shaped ceramic or metallic parts with high sintered density. However, dimensional accuracy of finished parts is difficult to achieve because of extremely high shear rates during the injection molding process. This promotes the separation of powder and binder ev...
