Parameter Variation in Planetary Ball Milling of Titanium Aluminide Powder in XHV‐Adequate Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Numerical Simulation of Factors Affecting Rotary Atomization of High Salinity Produced Water in Gas Fields

Shiyou jixie
The more concentrated the droplet size after atomization, the more easily the atomization process is controlled. Adjusting atomization parameters can reduce the operating cost of the produced water system of gas field and improve the treatment effect. In

Melt Damage and Prevention of Gas Nozzle Tip in Close-Coupled Gas Atomization

J
Gas atomization is one method for producing fine metal powder. In close-coupled gas atomization, a high-speed gas jet is ejected near the molten metal, and the molten metal is further broken down in the shear layer at the outer edge of the jet, producing

Roles of Atomizing Gas in Swirl Effervescent Atomization

International Journal of Engineering & Technology, 2018
Issues of propellant atomizing, mixing and viscous loss become increasingly more important as the thrust chamber are reduced in size. The present investigation examines the behavior of resulting sprays emanating from swirl effervescent atomizers at various gas-to-liquid ratios (GLRs) and aeration tube configurations. A series of cold flow test has been

Microstructure Design of Steel‐Spinel Composites via Spark Plasma Sintering Process

Advanced Engineering Materials, EarlyView.
This study illustrates how spark plasma sintering at reduced oxygen partial pressure enables controlled formation of steel‐spinel composites through tailored redox reactions and cation exchange. Comparison of the MgO–Fe2O3, steel–(MgO+Cr2O3), and steel–(MgO+Fe2O3) systems shows how oxygen activity and interface chemistry govern spinel formation, phase ...

Rapid solidification of metallic particulates [PDF]

In order to maximize the heat transfer coefficient the most important variable in rapid solidification is the powder particle size. The finer the particle size, the higher the solidification rate.
