| Abstract Scope |
High-entropy alloys (HEAs) are presently of great research interest in materials science and engineering. HEAs typically contain at least five elements with equimolar or near equimolar concentrations. Because of their high-entropy effects, HEAs have the potential to be used in many applications such as high temperature materials, cryogenic materials, wear resistance, diffusion barriers, etc. They are traditionally fabricated by vacuum melting method. However, this method produces microstructure defects such as shrinkage cavity, porosity, and segregation. In this study, spark plasma sintering (SPS) was used for diffusion bonding (cladding) of AlCrCoFeNi onto iron core (F-0008) for surface modification and corrosion resistance. SPS was carried out at 50 MPa and 1150˚C for 5 min. Results on the microstructure, interface characterization, and corrosion behavior are presented. |
