Abstract

In this research, the Erosion behavior of carbidic austempered Ductile iron and alloyed Ductile iron was studied and compared. For this purpose, cubic specimens with a size of 3*3*1 cm were prepared, and subsequently austempered. Microstructural characterization was carried out using optical microscopy and scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS). Hardness and surface roughness were measured prior to the Erosion test. Specimens underwent Erosion test at the angles of 30, 45, 60, 75, and 90 degrees. Diagrams depicting weight loss for different angles denote that the carbidic specimens show higher Erosion strength in all angels. Moreover, X-ray diffraction results from the surface of the carbidic specimens prior and after the Erosion test demonstrated that there is 38 percent residual austenite on the surface of the carbidic specimens after the Erosion test which provides evidence for the strain-induced transformation of austenite to martensite during Erosion test. Micro-hardness tests on the surface of the carbidic specimens after the Erosion test demonstrated an increase from 446 to 531 vickers due to the transformation. Moreover, as apparent from the SEM images, the dominant Erosion mechanism is cutting and ploughing at low (30-60 degrees) and high angles (60-90 degrees) is crack and micro crack, respectively.
