| Abstract Scope |
Metallic alloys with exceptional capabilities at elevated temperatures have been persistently sought to facilitate the advancement of high-temperature structural components in various applications. With regard to this, Co-Cr-W-Ni alloys have stimulated broad research interest owing to their superior softening resistance together with excellent cold and hot workability. Hence, appreciable effort has been focused on examining and further optimizing their high-temperature performances, yet, leaving behind their deformation behavior at ambient temperature less understood. In the present study, we aim to clarify the room-temperature deformation micro-mechanisms of Co-Cr-W-Ni alloys with the aid of coupled scanning electron microscope (SEM)/electron backscatter diffraction (EBSD) technique. We will systematically address: (i) what kind of deformation modules presents in these alloys? (ii) what is the corresponding defect sub-structure evolution characteristic? and (iii) what micro-event plays the dominant role in damage nucleation? |
