Besides its exceptional refractoriness, hardness, and resistance to electricity and corrosion, it is inert with superior biocompatibility; thus, it is presently utilized in biomedical and surgical domains. Alumina is used in various fields, including construction, abrasive or chemical waste cleaning, fuel cells, and microelectronics, among others [13,14]. Single-crystal alumina is used as a dental implant. If alumina is produced using particles smaller than 4 μm, the modulus of elasticity rises to 30 GPa, which may cause problems.Austenitic steels are commonly used in several industries because of their excellent properties, as they are highly corrosion resistant, tough, and weldable [1–3]. These properties make them preferred in implants, petrochemistry, automotive, and kitchen equipment. In particular, researchers have been making efforts to improve their mechanical properties without sacrificing their toughness.EFFECT OF AL2O3 ADDITION
