Abstract Multi-principal element alloys (MPEAs) are an emergent class of metallic materials that displays a huge range possible properties and applications. CrCoNi MPEAs attract great interest because they show good strength–ductility combinations, especially in Cr-rich non-equiatomic compositions. In this work, the Cr 40 Co 30 Ni MPEA was produced characterized at different annealing condition...

A new approach to modelling the microstructure evolution and yield strength in laser powder bed fusion components is introduced. Restoration mechanisms such as discontinuous dynamic recrystallization, continuous recovery were found be activated during of austenitic stainless steels; these are modelled both via classical Zener-Hollomon thermostatistical approaches. mechanism suggested for format...

It is shown that the size effect recently observed by Espinosa et al., fJ. Mech. Phys. Solids 51, 47 s2003dg in pure tension tests on free thin metallic films can be explained by the existence of a boundary layer of fixed thickness, located at the surface of the film that was attached onto the substrate during deposition. The boundary layer is influenced by the epitaxial effects of crystal grow...

The mechanical properties and microstructural developments of 321 stainless steel during thermomechanical process were investigated. The repetitive cold rolling and subsequent annealing were conducted to achieve nanocrystalline structure in an AISI 321 stainless steel. Heavily cold rolling at −20°C was conducted to form martensite in metastable austenitic steel. The process was followed by anne...

The ferrite fraction and phase distribution of duplex steels depend strongly on the temperature evolution during hot deformation are correlated to different mechanical behaviors as well cold deformation. Therefore, control microstructure forming is relevant for target-oriented material design. In flow stress modelling forming, influence beyond often neglected. present work, a new method demonst...
