Caking phenomena in amorphous food powders

Trends in Food Science & Technology, 1995
Abstract Caking of free-flowing powders during storage is a deleterious phenomenon that is ubiquitous in the feed, fertilizer and pharmaceutical industries, and of economical importance for low-moisture foods. Among other subjects related to caking of amorphous powders, the following aspects are reviewed in this article: (1) physical and ...

Deposition of Amorphous Aluminium Powder Using Cold Spray

International Thermal Spray Conference, 2012
Abstract Deposition of amorphous aluminium powder using cold spray technology as a corrosion prevention measure was studied. Amorphous aluminium (Al-Ni-Ce) powder was successfully deposited on 7000-series aluminium substrates using cold spray parameters of 1.7 MPa under compressed air and temperature of 450°C. The coatings were subjected

Crystallization kinetics of amorphous Ni78P22 powders and hydrogen adsorption on both amorphous and crystal alloy powders

Journal of Materials Science, 1988
A thermal and kinetic investigation of the behaviour of amorphous and crystal powder alloy Ni78P22 was performed in a hydrogen atomsphere. It was shown that the amorphous alloy absorbs hydrogen within the temperature range 393 to 520 K. After that it is transformed into the crystal (stable) state in two steps at 615 and 670 K, respectively, thus ...

Synthesis of amorphous/crystalline composite using electroless copper plated amorphous powder

Materials Science and Engineering: A, 2005
Abstract An amorphous/crystalline composite was synthesized by warm extrusion of copper-deposited Ni57Zr20Ti18Si3Sn2 amorphous powder. Electroless plating method was applied to deposit crystalline copper on Ni57Zr20Ti18Si3Sn2 amorphous powder after fabricating Ni57Zr20Ti18Si3Sn2 amorphous powder by gas-atomization technique.

Synthesis of bulk amorphous composites with three amorphous phases by consolidation of milled amorphous powders

Intermetallics, 2010
Abstract Bulk amorphous composite with three amorphous phases was fabricated by consolidation of milled amorphous composite powders. The amorphous composite powder was synthesized by a controlled milling process using the Cu-based amorphous powder blended with 30 vol% Zr-based amorphous powders.

Powder Injection Molding of Cu-Based Amorphous Powders and Fe-Based Metamorphic Powders

ASME 2008 2nd Multifunctional Nanocomposites and Nanomaterials, 2008
Powder injection molding (PIM) process was applied to Cu-based amorphous alloy powders and Fe-based metamorphic alloy powders, and microstructure, hardness, and wear resistance of the PIM products were analyzed. When Cu-based amorphous powders were injection-molded and sintered at 470 °C, sintering was not made since most of amorphous phases were ...

α-Al2O3 powders from amorphous alumina gel

Inorganic Materials, 2015
We have studied the properties of α-Al2O3 powders prepared from amorphous alumina gel. The powders have a small particle size owing to the low synthesis temperature. The sintering temperature of compacts produced by pressing the powders is lower than that in the case of powders prepared from hydroxide precursors. The sintered material has a homogeneous,
