Optimization of process parameters of cryogenic treatment on Al/Al2O3 MMCs by Taguchi method for tensile strength

Abstract

Engineering materials are given different types of treatment to impart desired properties to the materials to make them suitable for the intended application. The conventional method is heat treatment. It is being followed by many centuries but the treatment of materials below the room temperature is altogether a new concept to enhance the material properties. When the materials are subjected to deep freezing up to -196 0 C the change in the morphology results in the stability of microstructure & dimensions. Many researchers have proved the usefulness of cryogenic treatment on ferrous materials. But a very little amount of work has been found in the area of nonferrous materials. Taguchi approach was applied to optimize the process parameters of cryogenic treatment on Al6061-Al2O3 MMCs. The results were experimentally validated. It is found that, the Taguchi approach can be used as an effective tool in optimizing the process variables to minimise the laborious effort in conduction of experiments.

Experimental investigation and statistical modelling for assessing the sliding wear of Futilized Filament Fabrication (FFF) fabricated parts

“…This investigation considers not just the interplay of orientation with the other aspects, but also three distinct elements at three distinct levels. [23] It is clear that L9 is the appropriate orthogonal array here. A total of 9 different "trial" or "experiment" conditions can be entered across the rows of this array, and each variable or interaction can be assigned in the columns.…”
