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

The Effect of the Rheocast Process on the Microstructure and Mechanical Properties of

The effect of cooling slope parameters on the microstructure and mechanical properties of new Al-5.7Si-2Cu-0.3Mg alloys, is not readily available in the literature. Therefore, this study aimed at investigating the effect of pouring temperature and cooling slope

This paper aims to assess the role of Cu on Al-Si-Mg alloys, in a range of 0-5 wt%, qualitatively on microstructure, defect formation, in terms of porosity, and strength in the as-cast conditions. The ternary system of Al-Si-Mg, using the A356 alloy as a base material, were cast using the gradient solidification technique; applying three different solidifica tion rates to produce directional
