Kinetics of the Synthesis of Aluminum Boride by the Self-Propagating High-Temperature Synthesis Method

Ceramics, 2022
The influence of certain factors on the kinetics of the process of obtaining aluminum borides (burning rate, ingot formation, and phase separation) was investigated. In this study, we report the registration of diboride using the SHS protocol.

Atomic-scale grain boundary engineering to overcome hot-cracking in additively-manufactured superalloys [PDF]

, 2019
There are still debates regarding the mechanisms that lead to hot cracking in parts build by additive manufacturing (AM) of non-weldable Ni-based superalloys.

Features of the welded seam material crystalliza-tion in Ti-TiB alloy under electron-beam welding conditions

Mechanics and Advanced Technologies, 2023
Natural metal composite materials represent a promising class of modern structural materials that need to be welded. Such materials can be welded by fusion, as has been established with the Ti-TiB alloy as an example.

Effects of stoichiometry, purity, etching and distilling on resistance of MgB2 pellets and wire segments [PDF]

, 2002
We present a study of the effects of non-stoichiometry, boron purity, wire diameter and post-synthesis treatment (etching and Mg distilling) on the temperature dependent resistance and resistivity of sintered MgB2 pellets and wire segments.
