We have developed optical flow based techniques for finding the surface strain of an untreated sample of material from a sequence of images taken during the application of force from a test rig. Not all optical flow algorithms have suitable functional characteristics for this task, as image sequences are characterised by both shortand long-range displacements, non-rigid deformations, as well as...

The corrosion resistance of a Magnesium alloy is low and needs to be improved. This research aimed at corrosion-resistance improvement by supatterd deposition aluminium film, which is formed on the surface of AZ91 Magnesium-alloy. Corrosion resistance performed polarization curve measurement, was evaluated in quest of the corrosion rate using the Tafel extrapolation method, and conducted surfac...

This paper deals with the comparative study on the properties of Aluminium alloy (LM6-12%Si) castings in sand casting and Evaporative pattern casting (EPC) process. Thermocouples are used to measure the temperature of the casting during solidification. Signals from the thermocouples are connected to the DAQ (Data Acquisition Card) 6024E.The software development platform used for this applicatio...

Upon the isothermal oxidation of an ODS FeAl Grade 3 intermetallic alloy, a structured oxide scale is developed between 800 and 950o C. TEM studies have revealed a three-layered structure with a top nanoequiaxed alumina, a central alumina and a bottom Fe-Al spinel. At these temperatures, aluminium outward diffusion does not seem to be suppressed neither by the spinel sub-layer nor by the yttria...
