Effects of heat treatment and tensile deformation characteristics on the microstructure and martensitic transformation chracteristics have been studied in rapidly solidified Fe-24Mn-4Si-5Cr-5Co based alloy ribbon by using metallography, calorimetry, X-ray diffractometry and tensile test.
The volume fraction of ε martensite as well α' martensite is increased due to thermal stress relief and grain growth with increasing annealing temperature.
Yield stress of melt-spun ribbon is decreased with increasing wheel speed; yield stress is 40.6kgf/㎟ in the ribbon fabricated at a wheel speed of 50m/sec. It can be concluded that the dependence of yield stress is contributed to the microstructure of melt-spun ribbon.
