Characteristics and Evaluation of Al/Al2O3/SiC/Mg Nano-Powder on Perforated SS316L Composite Bimetallic Sheet

The enhancement of nuclear and high-temperature applications largely depends on the cladding procedure for the composition of bimetallic sheets made of stainless steel. The current study presents a modified version of a unique experimental set-up for a perforated substrate sheet with ball-milled, nano-scale clad powder reinforcement. To create the clad material, Al₂O₃, SiC nano-sized grain powders and Mg coarse grain powder were combined with fine Al powder particles using a ball milling technique. In parallel, SS316L substrate sheets were utilised to fabricate bimetallic composite sheets and were perforated at regular intervals for a specific area. In an inert gas environment, a conventional heating process with mild initial compaction was offered for the sintering process to progress upon. The influence of the processing on the interfaces is suggested by the microstructure, energy-dispersive X-ray (EDX) and micro-hardness results from different sites in the synthesised bimetallic composite sheet. The processing methods and how they affect the diffusion behaviour of the clad intersection and perforation zone are described in depth in this experimental study.
