Probing heat generation during tensile plastic deformation of a bulk metallic glass at cryogenic temperature
Brennhaugen, David Dominikus Eide; Georgarakis, Konstantinos; Yokoyama, Yoshihiko; Nakayama, Koji S.; Arnberg, Lars; Aune, Ragnhild Elizabeth (Journal article; Peer reviewed, 2018)Despite significant research efforts, the deformation and failure mechanisms of metallic glasses remain not well understood. In the absence of periodic structure, these materials typically deform in highly localized, thin ... -
Tensile properties of Zr70Ni16Cu6Al8 BMG at room and cryogenic temperatures
Brennhaugen, David Dominikus Eide; Georgarakis, Konstantinos; Yokoyama, Yoshihiko; Nakayama, Koji S.; Arnberg, Lars; Aune, Ragnhild Elizabeth (Journal article; Peer reviewed, 2018)The mechanical behaviour in tension of a hypoeutectic Zr70Ni16Cu6Al8 Bulk Metallic Glass (BMG) was studied at room (295 K) and cryogenic temperatures (150 K and 77 K) using various strain rates between 10−4 and 10−1 s−1. ... -
Thermal Dependence of Shear Banding in Zr70Ni16Cu6Al8 Bulk Metallic Glasses
Brennhaugen, David Dominikus Eide (Master thesis, 2014)Zr70Ni16Cu6Al8 bulk metallic glass samples were cast and prepared for tensiletesting. Tensile tests were done at temperatures 77 K, 150 K and 295K, over a range of effective strain rates between 10−5 and 10−1/s in order ...
