The ballistic response of the high strength, low alloy (HSLA-100) steel at ambient and temperatures of -400°C, -800°C and -1960°C is investigated in this work. Lambert-jonas equation is used to fit the experimental results into a curve. The effect of quenching on ballistic behavior of HSLA-100 is also studied. The experiments are conducted on 3mm thick rectangular specimens impacted by blunt ti...

This work is focused on understanding the significant factors affecting fatigue strength of laser-welded butt joints in thin high-strength low-alloy (HSLA) steel. The effects weld profile, imperfections, hardness, and residual stresses were considered to explain results found S-N curves four welded series. showed acceptable although series presented multiple-imperfections. analysis behavior at ...

The main goal of this study was to develop a new processing technology for a high-strength low-alloy (HSLA) steel in order to maximize the mechanical properties attainable at its low alloy levels. Samples of the steel were processed using thermal deformation schedules carried out in single-phase (γ) and dual-phase (γ + α) regions. The samples were rolled at unconventional finishing temperatures...
