It has been proved that an addition of boron carbide introduced as an inoculant to the chromium white cast iron changes the structure of castings. Castings after inoculation revealed a different structure with numerous grains. Primary precipitates of chromium carbide also appeared, reducing the mechanical properties of as-cast parts. Properly established heat treatment regime makes chromium iron castings regain their, originally high, mechanical properties.
