The TIG welding process has shallow penetration. addition of activated flux can increase the depth penetration weld, which is called A-TIG welding, so this study to analyze effect type and current on penetration, hardness, microstructure, corrosion rate. This used SUS 304 A36 materials with a thickness 6 mm are welded using variations Fe2O3, Cr2O3 in strength 100 amperes 120 amperes. To find ou...

When using traditional metallographic techniques, materials scientists often make assumptions about the shape, distribution and connectivity of three-dimensional features that lie buried within the material. Recent work has shown that these assumptions can be incorrect. An approach to threedimensional analysis of microstructures is demonstrated here in three different alloy steels. Proeutectoid...

For the wall-thickness reduction of components destined for pressurized gaseous hydrogen, widespread use high-strength martensitic steels has long been desired. However, their strong susceptibility to hydrogen-assisted fatigue crack growth (HA-FCG) is still limiting proactive applications. Here, we instead focused on pearlite as another potential reinforcing agent development new hydrogen-compa...
