The microstructure and mechanical properties of Mg-Zn-Ho-Zr alloys have been investigated in detail.The grain size of the as-cast Mg-Zn-Ho-Zr alloy was greatly
Ag/[BN/Copt]5/Ag and [BN/Ag/CoPt]5/Ag thin films were deposited on glass substrates by magnetron sputtering and then annealed in vacuum at 600℃ for 30 min.The
