| Abstract Scope |
The present work focuses on the comparative investigation of structure-property relationship between high Mn steel and bi-metallic hammers for clinker crusher application. Our earlier studies reported that high Mn steel witnesses severe embrittlement at ambient temperatures. The low thermal stability of high Mn steel at different temperatures has been the primary cause for the in-service failure of clinker crushers operations. In contrast, cladding of alloy steel with white cast iron for bimetallic hammers are potentially more capable for clinker crusher application when they are subjected to temperatures ranging within 250 - 500ºC. The microstructures reveals the constituents of transformed phases and its distribution along with the variation in grain sizes at different temperatures. The changes in microstructural features are further correlated to results of unnotched Charpy impact testing and wear testing that suggest the bimetallic hammers with distinct interfacial transition layers could be considered as candidate materials for this application. |
