Effect of varying preheating temperatures in electron beam powder bed fusion: Part I Assessment of the effective powder cake thermal conductivity [PDF]
arXiv, 2021 One of the major barriers in adapting the existing EB-PBF process parameters to a new powder material system is controlling the preheating conditions such that every layer of powder results in enough partial sintering to create a coherent powder cake. To be able to understand the powder sintering process and adapt it to other materials, we must look at

Nano-scale analysis of titanium dioxide fingerprint-development powders [PDF]
, 2008 Titanium dioxide based powders are regularly used in the development of latent fingerprints on dark surfaces. For analysis of prints on adhesive tapes, the titanium dioxide is suspended in a surfactant and used in the form of a small particle reagent ...

Development of competitive high-entropy alloys using commodity powders [PDF]
arXiv, 2021 One of the main drawbacks of the powder metallurgy route for High-Entropy Alloys (HEAs) is the unavailability of fully pre-alloyed powders in the market. Using commodity powders (commercial Ni, Fe and Co base fully pre-alloyed powders, fully available in large quantities and at competitive prices) to produce HEAs presents a completely new and ...

Thermal Properties of Powders [PDF]
, 1990 This paper presents measurements of the specific heats of various powders, including nylon, ABS, PVC, and two kinds of wax. An unsteady-state conduction technique is also presented for measuring the thermal conductivities of these powders at ...

Powders for powder bed fusion: a review [PDF]
Progress in Additive Manufacturing, 2019 The quality of powder used in powder bed-based additive manufacturing plays a key role concerning process performance and end part properties. Even though this is a generally accepted fact, there is still a lack of a comprehensive understanding of the powder property–part property relationship.
