Journal ArticleDOI
Change in microstructure of selectively laser melted AlSi10Mg alloy with heat treatments
TL;DR: In this paper, the authors examined changes in the microstructure and mechanical properties of AlSi10Mg alloy, initially fabricated using selective laser melting (SLM) combined with a powder-bed system, by applying heat treatments at temperatures of either 300 or 530°C.
Journal ArticleDOI
Ultrafine grained copper alloy sheets having both high strength and high electric conductivity
TL;DR: In this paper, the ultrafine grained (UFG) microstructure, mechanical properties and electric conductivity of the Cu alloys severely deformed by accumulative roll bonding (ARB) process were systematically investigated.
Journal ArticleDOI
Managing Both Strength and Ductility in Ultrafine Grained Steels

TL;DR: In this article, the UFG steels with ferrite single phase were shown to have high tensile ductility but limited tensile strength and uniform elongation, which was attributed to the early plastic instability in UFG microstructures.
Journal ArticleDOI
Crystallography of Fe2Al5 phase at the interface between solid Fe and liquid Al
TL;DR: In this paper, the microstructures and crystallographic features of a η-Fe2Al5 phase formed on pure Fe hot-dipped in a pure Al melt at 750°C were examined in order to understand the η phase layer formation having a saw-tooth morphology.
Journal ArticleDOI
A new route to fabricate ultrafine-grained structures in carbon steels without severe plastic deformation
TL;DR: In this paper, a low-carbon steel sheet with a duplex microstructure composed of ferrite and martensite was cold-rolled to 91% reduction in thickness, and then annealed at 620-655°C.
