Abstract

Abstract In recent years, various highly pathogenic viruses have spread worldwide, posing serious threats to human life and property, thus creating an urgent demand for antibacterial structural materials. In this study, we developed two types of antibacterial medium‐entropy alloys (MEAs): as‐cast (Fe 63.3 Mn 14 Si 9.1 Cr 9.8 C 3.8 ) 88‐ x Cu 12 Ag x ( x = 2, 4 at%) (which do not require antibacterial aging heat treatment) and heat‐treated (Fe 63.3 Mn 14 Si 9.1 Cr 9.8 C 3.8 ) 99.5‐ x Cu x Ag 0.5 ( x = 2, 4 at%) (abbreviated as Cu x Ag0.5 and Cu12Ag x ). Both MEAs exhibit in transformation‐induced plasticity (TRIP) and twinning‐induced plasticity effects, demonstrating outstanding mechanical properties. Compared…
