摘要

The present issue of the International Journal of Microstructure and Materials Properties comprises six spontaneous papers discussing mechanical and microstructure properties of various casting metallic and non-metallic ceramic composites.rnThe following papers have been included in this issue.rnCanales et al. studied mechanical properties in as-cast and heat treated Al-Si-Cu alloys. The specimens were cut from ingots with different chemical compositions and microstructure occurred at strong thermal gradient. Specimens with different microstructure were machined for tensile test in the as-cast and heat treatment conditions. The analyses showed that the mechanical properties are affected by the silicon amount. They also found that heat treating enhances the yield and tensile strength, but reduces the ductility of the various aluminium alloys.
