Abstract: In this present work, an attempt has been made to synthesize of elemental powder blend of 83.0Fe-13.5Cr-2.0Al-0.5Ti (alloy A), 79.0Fe-17.5Cr-2.0Al-0.5Ti(alloy B), 75.0Fe-21.5Cr-2.0Al-0.5Ti(alloy C), and 71.0Fe-25.5Cr-2.0Al-0.5Ti (alloy D), alloys with 1.0 nano-Y2O3 (all in wt %) dispersion by solid state mechanical alloying route and consolidate milled powder by different sintering methods high pressure sintering (HPS), hot isostatic pressing (HIP)[1, 2], pulse plasma sintering (PPS)[3],and hydrostatic extrusion (HE) etc). Following this mechano-chemical synthesis and consolidation, extensive effort has been undertaken to characterize the microstructural evolution by X-ray diffraction, scanning and transmission electron microscopy, scanning tunneling electron microscopy, energy disperse spectroscopy and asses mechanical properties including hardness, compressive strength, Young’s modulus, fracture toughness. The details synthesis and characterization was reported recently in Karak et...
