Abstract
Microstructures of the stainless-steel filament produced by glass coated melt spinning are investigated. In the filament formed by rapid quenching from the liquid state with the drawing process, micrograins of a new metastable phase having a tetragonal structure unit cell with a=2.64×10−10 m, c=3.55×10−10 m has been observed in the stable phase having the fcc austenitic structure.
These phases are transformed into a mixture of the second metastable phase and the fcc phase by heating at about 490°C and by heating above 650°C, the second metastable phase is transformed into the stable fcc austenitic phase.
