Abstract
The present work investigates the sintering behavior on ferritic (434L) stainless steel with the addition of phosphorus and copper in reducing atmosphere during solid-state and super-solidus liquid-phase sintering. The powders were compact at 600 MPa by single-acting uniaxial universal machine and sintered at solid-state and super-solidus liquid phase at 1100 °C and 1300 °C in hydrogen atmosphere, respectively. The sintered samples were examined for their micrograph, density, and mechanical properties as hardness, ultimate tensile strength, yield strength, and tensile rupture strength. The addition of phosphorus and copper has resulted in improved density by 3%, hardness by 42%, yield strength by 45%, ultimate tensile strength by 19%, respectively, and corrosion resistance improved by 3.35 times.
