The spheroidisation of VC carbides in high-vanadium cast iron

open access: yes, 2011
High-vanadium cast iron is a type of white cast iron, in which a regular fibrous γ + VC eutectic with about 20 vol.% of vanadium carbides crystallises. The paper presents the results of research during which the high-vanadium cast iron was subjected to ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

open access: yesEcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)
