Aceros sinterizados tratados al vapor para la fabricación de componentes de amortiguadores bitubo
In this work, properties of three sintered and steam treated alloyed irons were analysed. These materials were Fe+2Cu, Fe+0.6C+0.5Cu, and Fe+0.45P+2.5Cu, which were obtained by powder mixing. Once pressed and sintered, samples were steam treated (surface
