A technique for measuring the linear contraction during and after solidification of low-alloy steel was developed and used for examination of two commercial low-carbon and low-alloy steel grades. The effects of several experimental parameters on the

As-cast 7xxx series aluminum alloys experience a severe loss in ductility upon cooling and become brittle below 300 °C. In order to simulate the thermal stresses arising during casting, a thorough understanding of the thermal contraction behavior du

The understanding of the contraction behavior in high-strength wrought 7XXX-series alloys is very important for the analysis of stress–strain development and modeling of hot tearing and cold cracking in direct-chill casting. The linear thermal cont

Thermally induced strains and stresses developed during direct-chill (DC) semicontinuous casting of high strength aluminum alloys can result in formation of micro-cracks in different locations of the billet. Rapid propagation of such micro-cracks in

The effect of pre-deformation on precipitation hardening response as well as the work-hardening behavior of a binary Mg–Ca alloy are investigated. Our results show that application of 5% pre-deformation increases the precipitation hardening respons
