The use of Cu and Ti in Zn alloys improves mechanical properties as solid solution and dispersoid particles (grain refiners) may harden the material and reduce creep deformation. This is one of the main design problems for parts made with Zn alloys,

This paper describes the superplastic characteristics of shipbuilding steel deformed at 800 °C and a strain rate less than 0.001/s. After the superplastic deformation, the steel presents mixed fractures: by decohesion of the hard (pearlite and carbi

Characterization of mechanical properties at a micro and nano scale has become increasingly important for manufactured parts, though facilities with accurate and state-of-the-art equipment are scarce, expensive and not always available. For this reas
