In this paper, for Fe, Fe–3%Cr, Fe–4%Ni, Fe–Cr–Ni (SUS304L), and Fe–1.5%Mo alloyed steel powders,adsorption and desorption behaviors of water were investigated. The compacts made from the powders were heated in a steam pot for 60minutes, and were dried in an air-conditioned room. Additionally, the mass changes were measured accurately.<br>In case of Fe–Cr–Ni (SUS304L) and Fe–3%Cr powders, the weight of the compacts increased with steam treatment. The weight of the compacts returned again to initial weight by drying in the air-conditioned room. However, in case of Fe–4%Ni and Fe–1.5%Mo powders, in spite of the steam treatment, the weight decreased rather than the starting of the steam treatment. Furthermore, the weight did not return to the initial weight by drying. It is said that water molecule adsorbed physically or chemically on powder surface. In case of Fe–Cr–Ni (SUS304L) and Fe–3%Cr powders, it is thought that the water molecule adsorbed physically on the powder because the weight returned to the initial weight. However, in case of Fe–4%Ni and Fe–1.5%Mo powders, the weight did not return to initial weight. Therefore, it is thought that the water molecule adsorbed chemically. Furthermore, the water release behavior from the powders were measured by a gas-chromatograph analyzer.
