We review our recent results of the formation, fundamental properties. workability and applications of late transition metal base bulk glassy alloys which have been developed after the first synthesis of Fe-based bulk glassy, alloys by the copper mold casting method in 1995. The late metal transition base bulk glassy alloys were obtained in Fe-(Al,Ga)-(R,C,B,Si). Fe-(Cr,Mo)-(C,B). Fe-(Zr,Hf,N,b.Ta)-B. Fe-Ln-B(Ln = lanthanide metal). Fe-B-Si-Nb and Fe-Nd-Al for Fe-based allovs. Co-(Ta,Mo)-B and Co-B-Si-Nb for Co-based alloys. Ni-Nb-(Ti,Zr)-(Co,Ni) for Ni-based alloys. and Cu-Ti-(Zr,Hf). Cu-Al-(Zr,Hf). Cu-Ti-(Zr,Hf)-(Ni,Co) and Cu-Al-(Zr,Hf)-(Ag,Pd) for Cu-based alloys. These bulk glassy alloys exhibit useful engineering properties of high mechanical strength. large elastic elongation and high corrosion resistance. In addition, Fe- and Co-based bulk glassy alloys have good soft magnetic properties which cannot be obtained for conventional amorphous and crystalline type magnetic alloys. The Fe- and Ni-based bulk glassy, alloys have already been used in some application fields. These late transition metal base bulk glassy alloys are promising as new metallic engineering materials.
