Title

Microstructural Evolution and Mechanical Properties of Mo40/C93200 Bimetal Processed by Compound Casting

Pages

  46-57

Abstract

Compound casting refers to a process that is used to produce bimetals. This study investigates the Interface of Mo40/C93200 that is produced by Compound casting process. In this research, molten bronze is poured around the steel core, and interaction between liquid and solid creates a diffusion zone and is followed by a transition layer which leads to the creation of a diffused region between the Interfaces of metal layers. The results of micro-hardness and macro hardness tests were used to complete the studies. The results of the hardness of the Mo40 alloy revealed that the alloy micro-hardness was almost 308 Vickers which confirms the ferrite-pearlite state of microstructures. The results of metallography revealed that the boundary between steel and bronze alloys due to the difference in electric potential during etching evolved a galvanic cell and one section was formed as the cathode and the other section as the anode. In this situation, steel was corroded and bronze was protected. Also, the results of SEM show that the boundaries between two alloys have an acceptable adhesion and the strength of Interface is sufficient. The result of tensile test indicates that the final yield strength was about 800 MPa and the elongation increases by 2%, which is an acceptable value. It is also observed that the failure is a soft defect type and a sufficient connection between steel and bronze is formed.
