Abstract
Three types of iron and low ally steel powders were investigated to determinate their physical properties and surface morphology by SEM analysis. The powders were obtained by water atomization. The first type of powder is an iron powder (P1) and low alloy steel powders. Frequently, the alloying elements are copper, nickel and molybdenum (powders P2 and P3).
