316L Stainless Steel Powders for Additive Manufacturing: Relationships of Powder Rheology, Size, Size Distribution to Part Properties. [PDF]

Materials (Basel), 2020
Laser-Powder Bed Fusion (L-PBF) of metallic parts is a highly multivariate process. An understanding of powder feedstock properties is critical to ensure part quality.

Assessing the robustness of powder rheology and permeability measurements

Additive Manufacturing, 2020
Abstract Powder metallurgy processes rely on powder flowability. However, flowability is not an intrinsic property and depends on the measurement conditions. Standards have been developed to adjust measurement methods to various flow conditions but there is presently questions whether current methods are adapted to the specific requirements of powder

General aspects of powder rheology applied to pharmaceutical formulations

Drug Discovery Today
Powder flowability is crucial in the pharmaceutical industry, strongly affecting solid dosage processing. Classical experimental techniques offer straightforward results for the rapid screening of formulations during development. However, they fail to describe powder properties under consolidation.

Assessment of the effect of Cellets’ particle size on the flow in a Wurster fluid-bed coater via powder rheology

Journal of Drug Delivery Science and Technology, 2019
The main objective of this study was to investigate the effect of microcrystalline cellulose (MCC) spheres (Cellets) size effect on the powder properties to assess the possible impact of the Cellets’ size on the powder behaviour in the down-flow bed and ...

Effect of particle size and formulation on powder rheology

Particulate Science and Technology, 2020
Links between flow properties and formulation of powders of 100 and 500 µm mean particle sizes were investigated. To determine the influence of surface treatment, the flow properties of glass beads were analyzed after various surface treatments leading to hydrophilic, hydrophobic, and lactose-coated surfaces.

Experimental investigation of cohesive powder rheology

Powder Technology, 2000
An annular shear cell-type cohesive powder rheometer has been fabricated, which measures the shear and normal stress states over a range of shear rate and powder concentration. The rheological behavior of a 30-μm spherical silica powder and a 40-μm industrial polymer powder have been experimentally investigated for powder flow in the frictional regime.

Influence of powder state and rheology on sintering behaviour of SiC

Open Ceramics, 2021
The influence of conditioning state of a nano-SiC powder on its spark plasma sintering behaviour and microstructural properties is discussed. The powders were firstly deeply characterized by means of SEM, X-ray diffraction, specific surface area ...

Powder rheology and characterization of new and zinc recycled WC-6wt%Co powders

International Journal of Refractory Metals and Hard Materials
Four industrially manufactured WC-6wt%Co powders were studied in terms of bulk properties, morphology and powder rheology. Two powders, comprising 100 % fresh raw material, a 100 % zinc recycled powder and a powder comprising 60 wt% zinc recycled and 40 wt% new material, were investigated.
