engineering, industrial and natural processes. Particle-based computational modelling has …

Selective laser melting (SLM) is a near-net-shape time-and cost-effective manufacturing
technique, which can create strong and efficient components with potential applications in …

This work investigates the effects of powder characteristics, particularly particle size
distribution (PSD), on the micro-/defect-structure, tensile, and fatigue properties of Grade 23 …

Pulsed laser melting in liquid (PLML) has been developed to fabricate crystalline spherical
submicrometer particles (SMPs) by irradiating lasers onto raw particles dispersed in liquid …

Additive manufacturing based on powder spreading is attracting great interest, but one key
weakness is that narrow gaps used for spreading produce non-uniformity in the spread layer …

The quality and uniformity of the powder layer have a direct impact on the performance of
parts produced via powder bed fusion (PBF). Because powder layer properties depend on …

The flow behaviour of a powder is critical to its performance in many industrial applications
and manufacturing processes. Operations such as powder transfer, die filling and powder …

This research aims at evaluating the characteristics of the 5 wt.% B4C/Ti-6Al-4V composite
powder feedstock prepared by two different categories of mechanical mixing for powder bed …

Powder spreadability is critical to particle spread layer and thus the quality of final product in
powder-based additive manufacturing, but the metrics and the underlying mechanics have …

Spreadability of cohesive and frictional powder is critical in powder spreading of additive
manufacturing. Different to flowability, the experimental test techniques and underlying …
