Microstructure and Mechanical Properties of Hot Pressed 16.5CR Ferritic ODS Steel Developed Through Mechanical Alloying
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 2
Abstract
Two different ferritic oxide-dispersion-strengthened (ODS) steels compositions Fe–16.5Cr–0.89Mn-0.3Y2O3-2ZrO2 (Sample1) and Fe–16.5Cr–0.89Mn-0.3Y2O3-2ZrO2-2Al (Sample2) were prepared through Mechanical Alloying (MA) and X-Ray Diffraction (XRD) pattern were taken at different time intervals for confirming the Nano-crystallite size. Milled powders were consolidated at 1170OC at three different pressure levels of 30, 40 and 60 MPa respectively. Densification studies, micro-structural examination ,and mechanical properties evaluation were analyzed and reported in the current study. MA of the hot pressed powder at 60 MPa obtained the highest density, hardness ,and tensile strength compared with another pressure compact irrespective of its composition. Aluminum addition in the ferritic ODS steel lowers the density, hardness ,and elongation of the ferritic ODS steel samples
