Abstract: Local mechanical properties in aluminum cast components are inhomogeneous as a consequence of spatial distribution of microstructure, e.g., porosity, inclusions, grain size and arm spacing of secondary dendrites. In this work, the effect of porosity… read more here.

Abstract: Abstract Shear stress has been recognized as an important parameter, in addition to stress triaxiality and Lode parameter, that characterizes the stress state and influences the ductile fracture process. Micromechanical analyses are performed on a… read more here.

Abstract: Abstract Large numbers of voids inevitably exist in the metal ingot due to non-equilibrium solidification. Forging is an important technique to eliminate such internal defects and obtain sound products. However, the research regarding void evolution… read more here.
