Deformation mechanism map of Cu/Nb nanoscale metallic multilayers as a function of temperature and layer thickness
(Cornell University, 2017)
The mechanical properties and deformation mechanisms of Cu/Nb nanoscale metallic multilayers (NMMs) manufactured by accumulative roll bonding (ARB) are studied at 25C and 400C. Cu/Nb NMMs with individual layer thicknesses ...
Basal slip latent hardening by prism plane slip dislocations in sapphire (α-Al2O3)
(Elsevier, 2010)
The properties of sapphire (α-Al2O3) predeformed at T = 1450 °C by 〈〉{} prism plane slip and subsequently deformed in 〈〉(0 0 0 1) basal slip between 1050 and 1250 °C were investigated. The critical resolved shear stress ...
Correlation between microstructure and creep behavior in liquid-phase-sintered α-Silicon Carbide
(The American Ceramic Society, 2006)
The influence of increasing the sintering time from 1 to 7 h on the microstructure evolution and the mechanical properties at high temperature was studied in α-silicon carbide (α-SiC) sintered in argon atmosphere with ...
A critical assessment of the dislocation-driven model for superplasticity in yttria tetragonal zirconia polycrystals
(The American Ceramic Society, 2008)
In this paper, the origin of the threshold stress in pure 3 mol %-yttria tetragonal zirconia polycrystals (YTZP) is analysed in detail. At this regard, the two explanations reported in literature are discussed thoroughly. ...
α-Al2O3 sapphire and rubies deformed by dual basal slip at intermediate temperatures (900–1300 °C): I. Dislocation organization
(Elsevier, 2009)
Under a load orientation that hinders twinning and impedes fracture, sapphire and Cr-doped α-Al2O3 single crystals (rubies) were deformed from 1500 °C to slightly above the brittle to ductile transition temperature of 900 ...
Effect of atmosphere and sintering time on the microstructure and mechanical properties at high temperatures of alpha-SiC sintered with liquid phase Y2O3-Al2O3
(Elsevier, 2006)
The influence that the atmosphere (N2 or Ar) and sintering time have on microstructure evolution in liquid-phase-sintered α-SiC (LPS-α-SiC) and on its mechanical properties at high temperature was investigated. The ...
α-Al2O3 sapphire and rubies deformed by dual basal slip at intermediate temperatures (900–1300 °C): II. Dissociation and stacking faults
(Elsevier, 2009)
Sapphire and rubies (undoped and Cr-doped α-Al2O3 single crystals) have been deformed in compression at temperatures lower than those previously used in studies of dislocations in the basal slip plane. Above 1400 °C, several ...
Tensile deformation and fracture mechanisms of Cu/Nb nanolaminates studied by in situ TEM mechanical tests
(Elsevier, 2018)
The mechanisms of deformation and failure of Cu/Nb nanolaminates manufactured by accumulated roll bonding were analysed using in-situ TEM mechanical tests. Dog-bone small-scale tensile specimens were prepared using a ...
Effect of the heat treatment on the mechanical properties and microstructure of Scalmalloy® manufactured by Selective Laser Melting (SLM) under certified conditions
(Elsevier, 2023)
Mechanical properties and microstructure of Scalmalloy® processed by Selective Laser Melting (SLM) under certified conditions are studied. Two types of samples are considered: as-built and heat-treated at 325 °C for 4 h. ...
