Characterising powder flow properties – the need for a multivariate approach

open access: yesEPJ Web of Conferences, 2017
Despite their widespread and well-established use, powders are challenging materials to work with, as evidenced by the common problems encountered during storage and processing, as well as in the quality and consistency of final products.

Rheology of Powder (II)

open access: yesJournal of the Society of Materials Science, Japan, 1963
In the previous paper we reported that the internal friction of powder is related to the variation of void during tapping or the powder constant of Nutting's equation. And it was seen that the shearing stress increases pulsatively with the increase of shearing displacement and saturates gradually.In this study we carried out determination of pulsative ...

Analysis of rheological behaviour of titanium feedstocks formulated with a water-soluble binder system for powder injection moulding

open access: yes, 2014
Binder selection and formulation are critical in powder injection moulding. Binders play a key role in controlling the rheological properties of a feedstock and influence whether the resulting feedstock can be successfully injection moulded, debound and ...

Rheology and Stability of Saudi Cement for Oil Well Cementing

open access: yesJournal of King Saud University: Engineering Sciences, 1989
The suitability of some locally produced cement for oil well cementing has been investigated by means of chemical and physical analyses of powder cement, rheology and thickening time of slurries, and the compressive strength of set cement.
