Furthermore , we revealed , for the first time , that the interface between α2 and γm is the weakest , especially in the case of semicoherent interfaces ( 6° angle in the [ 1–10 ] direction ) , which provides good nucleation sites for cracks.Download : Download high-res image ( 322 Electron Beam Melting ( EBM ) is an increasingly used Additive Manufacturing ( AM ) technique employed by many industrial sectors , including the medical device and aerospace industries .
