Salient Technical Feature including Competing Feature

25mm wide 25-50 micron thick continuous glassy ribbon can be prepared by planar flow casting method using melt spinning system. It uses 1 kg (for ferrous alloy) capacity induction furnace. The liquid metal is poured on water cooled Cu-wheel which can rotate at a speed of 1000 -3000 rpm.The system can be operated in normal and controlled atmospheres. The type of alloys that can be prepared through this melt-spinning system are

Glassy magnetic alloys: Fe-Si-B, Fe-Ni-B, Co-Si-B

Nanostructured magnetic alloys: Fe-Nb-Cu-Si-B,Fe-Co-Nb-Si-B

Brazing alloys: Cu-Ni-Mn, Ni-Fe-Cr-B-Si

Ferromagnetic shape memory alloy: Ni-Mn-Ga, Co-Ni-AI
