(Universiti Malaysia Perlis, 2009-12-01)
Metal matrix composites (MMC) have attracted interest for application in numerous fields. Current available processing method have given many problems in the production metal matrix composites. Generally, the main problems ...
Water vapour effects on chromia forming alloys during cyclic oxidation
(Universiti Malaysia Perlis, 2009-12-01)
Fe-Cr model alloys (Cr: 9, 17, and 25 wt %) were subjected to cyclic oxidation in Ar-20O2, Ar-20O2-5H2O and Ar-10H2-5H2O (pO2= 3.6 x 10-22 atm) all in volume % atmospheres at 700oC. In general, increasing alloy chromium ...
Quantitative stereology for fractal dimensions of Aluminum Alloy AA6061 and AA6063
(Universiti Malaysia Perlis, 2009-12-01)
Fractal dimension is an increasingly important method in material sciences. The searching for a possible correlation between fractal dimension and impact energy are current interest. This paper present the results of an ...
