Microwave-Assisted Sintering of Al–ZrO2 Nano-Composites
Abstract In this project, nano-ZrO2 particles were dispersed in aluminum powder by a Y-shape mixer. The particle size of ZrO2 powder was < 40 nm and the amount of ZrO2 reinforcement varies from 3 to 15%.The mixed powders were compacted .Subsequently the compacted discs were sintered both in the microwave oven and in the conventional muffle furnace .Using microwave –assisted sintering method led...
متن کاملDirect Laser Sintering of Ceramics
For more than one decade layer manufacturing technologies assist the development of new products. Due to a layer-wise build-up of a three-dimensional geometry, nearly every complex design is producible in a short period of time. Selective Laser Sintering is a powderbased technique to produce plastic prototypes (Rapid Prototyping) or metal mould inserts (Rapid Tooling). The laser sintering of ce...
متن کاملThermal Stresses in Direct Metal Laser Sintering
In Direct Metal Laser Sintering objects are created by sequential sintering loose metal powder particles by means of laser technology. When the laser sintering process involves temperature gradients, thermal stresses develop. Corresponding residual stresses induce warping of the densified structure leading to unacceptable tolerance losses. This paper examines the role of laser beam scan pattern...
متن کاملPractical Issues in the Application of Direct Metal Laser Sintering
Direct Metal Laser Sintering (DMLS) was introduced to meet the objective of producing metal parts directly from CAD data. CRDM has accumulated six years of experience in applying this technique, mostly to prototyping parts for evaluation. For some applications, such as blow moulds, porosity generated in DMLS has proved to be beneficial, but for others a concession on tolerances or finish are ne...
متن کامل[Article] From Powders to Dense Metal Parts: Characterization of a Commercial AlSiMg Alloy Processed through Direct Metal Laser Sintering
In this paper, a characterization of an AlSiMg alloy processed by direct metal laser sintering (DMLS) is presented, from the analysis of the starting powders, in terms of size, morphology and chemical composition, through to the evaluation of mechanical and microstructural properties of specimens built along different orientations parallel and perpendicular to the powder deposition plane. With ...
