Abstract:
Hypereutectic high chromium white cast iron alloys were produced with TiBAl (1-3 wt.%) inoculants. The heat treatments were applied to the samples as 1000 degrees C for 1 and 2 h. The microstructures of the samples were investigated by SEM. The chemical concentrations of matrix and carbides were determined by EDS and XRD to detect the type of carbides and matrix. The surface hardness of the samples was detected as HRC. The images of the fracture surfaces of the samples were examined by SEM. The toughness of the samples was evaluated by using charpy V-notch samples to detect the relationship between inoculation, carbide size and fracture toughness. (C) 2016 Elsevier B.V.
