Hot Consolidation of Titanium Powders

open access: yesPowders, 2023
A novel method of the hot consolidation metal powders with shear deformation is proposed. The powders were encapsulated into tight containers and compacted after short-term heating in a furnace preheated to 900 °C.

The Measurement of the Thermal Properties and Absorptances of Powders Near their Melting Temperatures [PDF]

open access: yes, 1991
A new technique, using a laser as the heating source, has been adopted to measure the heat capacities, thermal diffusivities, thermal conductivities, and absorptances of powders (especially polymer powders) near their melting temperatures.

Survival of thermophilic spore-forming bacteria in a 90+ year old milk powder from Ernest Shackelton's Cape Royds Hut in Antarctica [PDF]

open access: yes, 2000
Milk powder taken to Antarctica on Shackelton's British Antarctic Expedition in 1907 was produced in New Zealand by a roller drying process in the first factory in the world dedicated to this process. Thermophilic bacilli are the dominant contaminants of

Conceptual Design of a Pilot Process for Manufacturing Aluminum-Based Intermetallic Compound Powders

open access: yesPowders, 2023
The FeAl intermetallic compound is of great interest for industry due to its low density, low cost and high mechanical and corrosion resistance, so it can replace stainless steels and nickel-based alloys for some applications.
