Plasticity and microstructure of Zr–Cu–Al bulk metallic glasses
Description/Abstract:
A small variation in the composition of (Zr50Cu50)100−xAlx bulk metallic glasses (BMGs) results in a markedly different mechanical behavi...

Process parameters and magnetic properties (coercivity, remanence, squareness, maximum energy product) of data-driven fabrication of Nd-Fe-B anisotropic magnets by direct hot extrusion.
Description/Abstract:
We implemented an active learning pipeline assisted by machine learning and Bayesian optimization (ALMLBO) for predicting magnetic proper...
