Abstract
Iron based alloys Fe(82-x)-Cr18-Six (x = 0, 1, 2, 3) wt% were developed by mechanical alloying (MA). Phase evolution studies on the milled powders were conducted using X-ray diffraction (XRD) and field emission transmission electron microscopy (FE-TEM). Scanning electron microscope (SEM) was used to carry out morphological investigations. Results showed an initial solid solution formation at 5 h of milling and with continued milling to 35 h, an amorphous phase was formed. The amorphous phase was mechanically crystallized to α-phase at 85 h and 100 h of milling for Fe(82-x)-Cr18-Six (x = 0) and Fe(82-x)-Cr18-Six (x = 1, 2, 3) wt% alloys respectively. Both the lattice parameter and crystallite size were decreased with an increase in Si content of the alloys. With continued milling, micro-strain was increased and crystallite size of the alloys was decreased.
