Inoculation of chromium white cast iron

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.
