magnitude was the dispersive one. With respect to the characterisation
of macroscopic powder flow behaviour, the yield locus and flow
function dependencies at different stress levels for the studied samples
were determined. It was found that the character of the flow was
cohesive (

= 3.24). The effective angle of internal friction was found
to be 40.75° and the angle of internal friction was 31.9°.
