Identifying the most significant parameter in stir casting process for optimizing the effect of nano reinforcement MWCNT on AA 7075-T651

Abstract

The purpose of this research is to determine the most important factors affecting the mechanical properties of hybrid aluminum metal matrix composites (MMCs). The literature review and the pilot experiments both helped to determine which variables were most and least important. The fishbone diagram visually represented the identified elements, but it ignored the meaning of the responses provided. FMEA, which stands for Failure Mode and Effect Analysis, was used to identify critical parameters from among all of the elements shown in the fishbone diagram. After that, we used a Plackett–Burman layout to narrow down the list of relevant elements and identify the most influential ones. It was found that stirring time, speed, and reinforcement were among the most crucial factors in achieving ultimate tensile strength (UTS) is high, and Hardness.
