Low cycle fatigue behaviors in Nb-bearing high strength, low alloy (HSLA) steel have been studied at plastic strain amplitudes Aep/2 ranging from 1 x 10 -5 to 1 x 10 -2 in air and in ultrahigh vacuum (UHV). Microcracks are initiated along slip lines both in air and in UHV, and grain boundaries act a
Ah&met-Welded and unwelded specimens of an air-melted laminar composite steel armor were tested for degradation of strength from ballistic impact. Specimens were impacted with cal. 0.30 AP and ball projectiles at various velocities and O-degree obliquity. During impact, specimens were tensile loaded
