Application of Machine Learning to Mechanical Properties of Copper Graphene Composites [PDF]
arXiv, 2022 While copper-graphene (Cu/Gr) composites have been promising materials due to their theoretically high strength and conductivity, their design has been hampered by the large number of variables affecting their properties. We applied four different Machine Learning (ML) models to manually collected datasets compiling the yield strength and ultimate ...

An Atom-Probe Tomographic Study of the Compositional Trajectories During gamma(f.c.c.)/gamma-prime(L12) Phase-Separation in a Ni-Al-Cr-Re Superalloy [PDF]
arXiv, 2019 The compositional diffusional-trajectories for a phase separation of gamma(f.c.c.)/gamma-prime(L12) phases are studied in a quaternary Ni-10Al-8.5Cr-2Re alloy, aged at 700 deg.C for 0 to 1024 h, utilizing atom-probe tomography (APT). As the gamma-prime(L12)-precipitates grow, the enrichments of Ni, Cr, and Re and depletion of Al on the gamma(f.c.c ...

A Series of Plasma Innovation Technologies by Double Glow Discharge Phenomenon [PDF]
arXiv, 2020 In order to break the limitation of plasma nitriding technology,which can be applied to a few nonmetallic gaseous elements, the "Double Glow Discharge Phenomenon" was found and then invented the "Double Glow Plasma Surface Metallurgy Technology". This double glow plasma surface metallurgy technology can use any element in the periodic table of chemical
