dc.description.abstractThe objective of this study was to determine the effects of powder metallurgy process parameters on the porosity, coefficient of thermal expansion, and oxidation behaviors of porous ferritic Fe22Cr stainless steel compacts. Optimum values of the process were also investigated. The results showed that, porosity and the coefficient of thermal expansion decrease with increasing process parameters; and changing powder shape from spherical to flaky at a certain extent. The minimum and maximum porosity values of the samples were recorded as 7% and 30%, respectively. While those for the samples produced from milled powders were noted as 3%, and 19%, respectively. The coefficient of thermal expansion values were measured at 800 degrees C and found to be in the range of 12-14.5 x 10(-6) K-1 for spherical powders and flaky powders. From oxidation kinetics point of view, both process parameters and powder shape influenced the oxidation behavior. (C) 2020 Elsevier B.V. All rights reserved.
