Description
Summary:•SEN alloys are developed by adding small amounts of Ca and Y to Mg–Al-based alloys.•SEN alloys exhibit enhanced oxidation, ignition, and corrosion resistances.•SEN9 alloy has superior tensile properties and comparable fatigue properties to AZ91 alloy.•The formation of brittle Mg17Al12 DPs during aging is suppressed in SEN alloys.•SEN9–0.5MM alloy exhibits excellent extrudability with a maximum speed of 12 mm/s. This review article provides overall understanding of stainless, environment-friendly, and nonflammable Mg alloys (SEN alloys) recently developed at the Korea Institute of Materials Science. SEN alloys are produced by adding small amounts of Ca and Y (each
