A computational study of how surfaces affect slip family activity
Cathy Bing, Thomas R. Bieler, Philip Eisenlohr
Plastic deformation behavior is most conveniently assessed by characterization on a surface, but whether such observations are representative of bulk properties is uncertain. Motiv…
Grain boundary slip transfer classification and metric selection with artificial neural networks
Zhuowen Zhao, Thomas R. Bieler, Javier LLorca +1
An artificial neural network is used to evaluate the effectiveness of six metrics and their combinations to assess whether slip transfers across grain boundaries in coarse-grained…
A criterion for slip transfer at grain boundaries in Al
R. Alizadeh, M. Peña-Ortega, T. R. Bieler +1
The slip transfer phenomenon was studied at the grain boundaries of pure Aluminum by means of slip trace analysis. Either slip transfer or blocked slip was analyzed in more than 25…
Effect of slip transmission at grain boundaries in Al bicrystals
S. Haouala, R. Alizadeh, T. R. Bieler +2
The effect of slip transfer on the deformation mechanisms of Al bicrystals was explored using a rate-dependent dislocation-based crystal plasticity model. Three different types of…
High Frequency Nonlinear Response of Superconducting Cavity-Grade Nb surfaces
Bakhrom Oripov, Thomas Bieler, Gianluigi Ciovati +9
Nb Superconducting Radio-Frequency (SRF) cavities are observed to break down and lose their high-Q superconducting properties at accelerating gradients below the limits imposed by…
An analysis of (the lack of) slip transfer between near-cube oriented grains in pure Al
T. R Bieler, R. Alizadeh, M. Peña-Ortega +1
Slip transfer across grain boundaries was studied in annealed polycrystalline Al foils deformed in uniaxial tension by means of the analysis of the slip traces on the specimen surf…
Revealing the role of nitrogen on hydride nucleation and stability in pure niobium using first principles calculations
P. Garg, S. Balachandran, I. Adlakha +3
Niobium provides the basis for all superconducting radio frequency (SRF) cavities in use, however, hydrogen is readily absorbed by niobium during cavity fabrication and subsequent…
Nanoscale Nonlinear Radio Frequency Properties of Bulk Nb : Origins of Extrinsic Nonlinear Effects
Tamin Tai, B. G. Ghamsari, T. Bieler +1
The performance of Niobium-based Superconducting Radio Frequency (SRF) particle accelerator cavities can be sensitive to localized defects that give rise to quenches at high accele…
Near-Field Microwave Magnetic Nanoscopy of Superconducting Radio Frequency Cavity Materials
Tamin Tai, Behnood G. Ghamsari, Thomas R. Bieler +3
A localized measurement of the RF critical field on superconducting radio frequency (SRF) cavity materials is a key step to identify specific defects that produce quenches of SRF c…
