Over the past few decades, the automotive industry has seen a steady increase in the amount of powder metallurgy products that have been included in modern vehicles. The majority of the parts were cold press and sintered products that allowed for a high production volume and low cost option. In more recent years, the powder metallurgy parts have seen service as structural parts mainly consisting of steel base products. The mechanical and dynamic properties of four lightweight materials produced by powder metallurgy and additive manufactured are tested to determine if they are suitable to be used in a structural part within an internal combustion engine. The research concluded that an additive manufactured titanium material was the only tested material that met or exceeded the current requirements for strength to be a suitable material. The selected material showed low porosity that resulted in suitable fatigue and mechanical properties for a possible substation of the reference material.
