Hydrogen Insertion into Complex-Phase High-Strength Steel during Atmospheric Corrosion at Low Relative Humidity
نویسندگان
چکیده
Atmospheric corrosion is one of the major sources hydrogen in a high-strength-steel product service. Even low concentrations absorbed can cause embrittlement-related material degradation. The extent atmospheric and thus related entry highly dependent on environmental parameters, such as relative humidity. present work focused at humidity, where rates are expected to be low. Hydrogen insertion distribution CP1000 steel induced by under dried rewetted single droplets aqueous NaCl MgCl2 solution were studied using Scanning Kelvin Probe (SKP) resulting amounts diffusible analyzed thermal desorption mass spectrometry (TDMS). Corrosion analyses carried out with SEM/EDX, XRD, Mössbauer spectroscopy. results revealed strong impact salt type concentration into steel. hygroscopic effect formed products responsible for prolonged even very levels

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...
