Abstract

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.

穿孔 SS316L 复合双金属片上的 Al/Al2O3/SiC/Mg 纳米粉体的特性与评估

核能和高温应用的增强在很大程度上取决于不锈钢双金属片成分的包覆程序。目前的研究介绍了一种独特实验装置的改进版，该装置用于带有球磨纳米级包覆粉末增强材料的穿孔基板薄片。为了制造覆层材料，使用球磨技术将 Al2O3、SiC 纳米颗粒粉末和 Mg 粗颗粒粉末与细小的 Al 粉末颗粒结合在一起。同时，利用 SS316L 基板制造双金属复合板材，并在特定区域以一定间隔穿孔。在惰性气体环境中，烧结过程采用传统的加热工艺，初始压实度较低。合成双金属复合片材不同部位的微观结构、能量色散 X 射线（EDX）和显微硬度结果表明了加工过程对界面的影响。本实验研究深入阐述了加工方法及其如何影响包层交叉点和穿孔区的扩散行为。
