E-beam-enhanced solid-state mechanical amorphization of alpha-quartz: Reducing deformation barrier via localized excess electrons as mobile anions
Sung-Gyu Kang, Wonseok Jeong, Hwangsun Kim +4
Under hydrostatic pressure, alpha-quartz undergoes solid-state mechanical amorphization wherein the interpenetration of SiO4 tetrahedra occurs and the material loses crystallinity.…
Green laser powder bed fusion based fabrication and rate-dependent mechanical properties of copper lattices
Sung-Gyu Kang, Ramil Gainov, Daniel Heußen +5
Lattice structures composed of periodic solid frames and pores can be utilized in energy absorption applications due to their high specific strength and large deformation. However,…
Glass shaping at nanoscale: Mechanical forming of brittle amorphous silica by engineered inelastic interaction of scanning electrons with matter
Sung-gyu Kang, Kyeongjae Jeong, Woo Jin Cho +5
Amorphous silica deforms viscoplastically at elevated temperatures, as is common for brittle glasses. The key mechanism of viscoplastic deformation involves interatomic bond switch…
