Microstructure and abrasive wear properties of Hi-C medium chromium wear resistant alloy steels after heat treatment (2)

January 22, 2021/in Castings /by Sara Wu

1.1 Heat treatment process Five quenching temperatures were designed: 860 ° C, 900 ° C, 940 ° C, 980 ° C, 1020 ° C, according to the phase composition calculation of wear-resistant alloy steel at different temperatures by JmatPro and the phase diagram analysis of Fe-C-Cr ternary alloy in longitudinal section. The heat treatment process […]

2.4 Low-magnification analysis In order to further analyze the material quality of the dia90 mm low chromium cast grinding ball, the sample was taken at the fracture position parallel to and close to fracturing by electric spark cutting method. The sample was polished by grinding wheel and heated to about 70 °C in 50% hydrochloric […]

2.3 Metallographic test With the hardness mentioned above test samples, the metallographic samples were prepared near the fracture point, polished and polished without erosion at 100-fold optical. Non-metallic inclusions were detected under the microscope. The results are shown in Table 2 and Figure 2.
