Modelling and Microstructural Characterization of Sintered Metallic Porous Materials

This paper presents selected characteristics of the metallic porous materials produced by the sintering of metal powders. The authors focus on materials produced from the iron powder (Fe) of ASC 100.29 and Distaloy SE. ASC 100.29 is formed by atomization and has a characteristic morphology. It consists of spherical particles of different sizes forming agglomerates. Distaloy SE is also based on ...

Simulated Microstructural Evolution and Design of Porous Sintered Wicks

Porous structures formed by sintering of powders, which involves material-bonding under the application of heat, are commonly employed as capillary wicks in two-phase heat transport devices such as heat pipes. These sintered wicks are often fabricated in an ad hoc manner, and their microstructure is not optimized for fluid and thermal performance. Understanding the role of sintering kinetics—an...

Characterization of loose powder sintered porous titanium and Ti6Al4V alloy

Porous titanium and Ti6Al4V alloy, biomedical candidate materials for use in orthopedic and dental implants, were manufactured by sintering the powders at various temperatures in loose condition. The characteristics of the corresponding powders and utilized sintering temperatures limited the final porosities in the range 30-37.5 vol. %. Similar to wrought alloys, compression stress-strain curve...

METALLIC AND CERAMIC MATERIALS RESEARCH Task Order 0005: Metallic, Materials, Methods, Characterization and Testing Research

Flow in porous metallic materials: a magnetic resonance imaging study.

PURPOSE To visualize flow dynamics of analytes inside porous metallic materials with laser-detected magnetic resonance imaging (MRI). MATERIALS AND METHODS We examine the flow of nuclear-polarized water in a porous stainless steel cylinder. Laser-detected MRI utilizes a sensitive optical atomic magnetometer as the detector. Imaging was performed in a remote-detection mode: the encoding was co...
