/in Castings, Heat Treatment Process /by Sara WuNing Jiapei, Zheng Kaihong, Zhou Hongming, Wang Haiyan, Long Jun) (1. School of Materials Science and Engineering, Central South University, Changsha, Hunan 410083, China;2.Guangdong Institute of Materials and Processing, Guangzhou 510651, China) Abstract: The effect of quenching temperature on microstructure and mechanical properties of medium chromium wear resistant alloy steel was studied. The mechanical properties […]
Failure analysis of 90mm low chromium cast ball cracking (3)
/in Grinding media balls /by Sara Wu2.4 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 […]
Failure analysis of 90mm low chromium casting ball cracking (2)
/in Grinding media balls /by Sara Wu2.3 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.
Failure analysis of 90mm low chromium casting ball cracking (1)
/in Grinding media balls /by Sara WuLU Weidong , SHEN Maolin , ZHOU Yuanxing (Institute of Ningguo Wear Resistant Materials General Plant Anhui Province, Ningguo 242300 , China) Abstract: The cracking of the 90mm low chromium casting ball occurred too early in the drop ball test. The casting ball material was analyzed by chemical composition, mechanical properties, and metallographic structure. The […]
