Influence of Powder Deposition on Powder Bed and Specimen Properties

Effects of powder recycling on stainless steel powder and built material properties in metal powder bed fusion processes

Influence of Ultrafine 2CaO·SiO2 Powder on Hydration Properties of Reactive Powder Concrete

In this research, we assessed the influence of an ultrafine 2CaO·SiO₂ powder on the hydration properties of a reactive powder concrete system. The ultrafine powder was manufactured through chemical combustion method. The morphology of ultrafine powder and the development of hydration products in the cement paste prepared with ultrafine powder were investigated by scanning electron microscopy (S...

Milk powder agglomerate growth and properties in fluidized bed agglomeration

Fluidized bed agglomeration is used to produce large and porous dry agglomerates with improved instant properties. Water (or binder solution) is sprayed in the fluidized bed of particles to render their surface sticky. The agglomerate growth results from the repetition of different steps (wetting of the particle surface, particles collision and bridging, and drying) and depends on the processin...

The Influence of Aloe Vera Powder on Dough Properties and the Quality of Barbari Bread

ABSTRACT: Barbari is traditional flat leavened Iranian bread and one of the most popular breads consumed in Iran. Barbari bread stales quite fast and its shelf life is very short. Therefore, the addition of bread improvers and anti-staling agents, such as aloe vera, is a suitable method for extending the shelf life of the bread. In the present study, the effect of aloe vera powder at 0, 1, 3, 6...

The Effect of Powder Recycling in Direct Metal Laser Deposition on Powder and Manufactured Part Characteristics

A potential way of improving the material efficiency and cost effectiveness of the Direct Metal Laser Deposition (DMLD) process is to take powder that is not utilised in each deposition attempt and re-use it in subsequent attempts (powder recycling). Currently, this is not widely implemented for fear of a detrimental effect on part quality. This study examines how powder recycling, using simple...
