Difficulties in the Production of Ausferritic Nodular Cast Iron without Heat Treatment [PDF]
Archives of Foundry Engineering, 2023 The paper presents results of tests carried out on ausferrite carbide matrix alloyed ductile cast iron. The ausferrite was obtained via addition of Cu and Mo alloying elements. This eliminated heat treatment from the alloy production cycle.
