AlB2‐KAlF4 composites were fabricated via SHS using Al and KBF4. Phase evolution, microstructure, and reaction mechanism were characterized. KBF4/Al melting initiates the reaction; BF3‐Al redox yields AlB2 and KAIF4 with distinct morphologies. ABSTRACT Using Al and KBF4 as raw materials, AlB2‐KAlF4 composites were synthesized by self‐propagating high ...

Modeling Refractory Material Production by Self-Propagating High Temperature Synthesis (SHS)
Self-propagating high temperature synthesis (SHS) can be used to prepare near net refractory shapes which are difficult to produce by other methods. In SHS, green compacts capable of strong exothermal reaction are ignited at one end and transformed into ...

Kinetic Insights Into Boron–Carbon Interaction Under Programmed Heating
This work demonstrates the decisive role of the heating rate and short‐term mechanical activation in governing the boron–carbon interaction. The combined effect of rapid heating and mechanical activation enables the 4B + C reaction to proceed at significantly lower temperatures. For the first time, the effective activation energy of the 4B + C reaction

ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.
