Microstructure and Impact Toughness of High-Strength Low-Alloy Steel after Tempforming
نویسندگان
چکیده
The effects of temperature and degree tempforming deformation on the microstructure impact toughness high-strength low-alloy 25KhGMT steel have been considered. Tempforming forms a lamellar composed grains subgrains that are strongly elongated along rolling direction. average size grain section is 570–790 nm. Deformation texture includes ?001? || ND ?111? fibers. increases fracture work this at lower test temperatures (KV–40°? ? 360 J) due to delamination specimen perpendicular direction, which prevents crack propagation towards direction impact.

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...

The aim of this study is to reach an increased service life for parts using in sour environment by weld overlaying process. In this investigation, two successive layers of ER410NiMo were clad on low alloy steel substrates. To reduce the likelihood of Hydrogen Induced Cracking (HIC) and producing stable hydrogen traps, Post Weld Heat Treatment (PWHT) was conducted. Microstructural analysis, X-ra...
