Effect of cooling rate on microstructure and mechanical

Castings of Al–Cu–Mg alloy with different section thickness were prepared by gravity casting and squeeze casting, and microstructure and mechanical properties of the castings were studied. The experimental results show that squeeze casting results in considerable microstructure refinement and reduction of shrinkage porosity compared with gravity casting due to a marked increase in cooling

Investigation of Porosity and Mechanical Properties of

In order to numerically investigate the effect of pores on material properties, the porosity of material must be quantified at first. In order to do this, the planer metallographical images with 2048 1536 pixels at 40 magnification are converted into binary black and white format, which only highlights the pores' morphologies while other metallurgical information is eliminated, as shown
