Thermomechanical Behavior of Rapidly Solidified Fe-25Cr-20Ni
The thermomechanical treatment at 1050°C under a stress of about 30 MPa, of milled ribbons from Fe-25Cr-20Ni (0.060%Ni-0.1%Ti) refractory stainless steel, leads to a recrystallisation of the as-melt-spun structure which is intermediate between cellular and columnar dendritic. The mean grain size in the relatively high density zones (85%) may be considered as low and do not exceed 10µm. Other grains appear abnormally large and reach 30µm. The origin of these grains, must be researched in an exaggerate growth phenomenon under a local deformation near the critical work hardening.
