Laser cutting of metal matrix composite, having extensive applications in aerospace and automobile industries, is important from the eminence of cut point of view. Keeping this in view, a fusion approach of Taguchi method (TM) and principal component analysis (PCA) has been functional for multi-objective optimization (MOO) of pulsed Nd: YAG laser beam cutting (LBC) of Al7075/SiCp metal matrix c...

The analysis of steady state creep in a rotating disc made of Al-SiCp composite having variable thickness has been carried using Sherby’s constitutive model. The creep parameters have been evaluated using the available experimental results in the literature using regression analysis. Three variations in the thickness (constant, linearly and hyperbolic varying thickness) of the disc have been co...

The initial discharge process of plasma electrolytic oxidation (PEO) on the 60 vol. % SiCP/2009 aluminum matrix composite in silicate solution was situ monitored by sound and vibration measurement techniques. underwater sound, airborne sample signals were detected 120 s PEO process, their generation mechanism discussed. In terms waveforms spectrograms signals, can be divided into five stages: c...
