Spatial microstructural response in a high-strength low-alloy steel fabricated by wire-arc direct energy deposition under projectile penetration

Runhuan Cai, G. R. Bai, Fei Chang, Siyi Li et autres

The spatial microstructural response under projectile penetration was investigated in a high strength low alloy (HSLA) steels fabricated by wire arc directed energy deposition (DED). Projectile penetration induces pronounced spatial heterogeneity because of severe local thermomechanical gradients. This heterogeneous response is controlled …
