| Abstract Scope |
This article summarizes the characteristics and research on alloyed white cast iron, noted for its excellent mechanical and tribological properties due to carbon forming carbides. Its microstructure is controllable via alloying, cooling rates, modifiers, and spheroidizers, though production is technologically challenging, often needing protective or vacuum atmospheres.
High-alloy white irons are vital for abrasion-resistant applications like crushing. They offer high hardness (450-800 HB) but face brittleness, mitigated by elements like silicon and molybdenum.
Recent research on high-vanadium cast iron (9-15% V) explored its microstructure across different compositions. Studies detailed how silicon, cooling rate, and other elements impact vanadium carbide morphology and spheroidization, making this cast iron very ductile, as well as complex carbide crystallization. Controlling the liquid metal's state during casting is crucial.
Advanced analytical techniques like optical microscopy, SEM, EDX, WDS, EBSD, and thermal analysis were employed for comprehensive material characterization. |
