In this research the interface structure of dissimilar joint between AISI 4130 and AISI316L steels produced by GTAW process was evaluated. ERNiCr-3 was used as a filler metal for this joint. After welding the microstructure of different areas including weld metals, heat affected zones and interfaces were studied by optical microscope (OM), scanning electron microscope (SEM) and energy dispersiv...

In this study the effects of surface texture on the fatigue life of a high-strength low-alloy steel were evaluated in terms of the apparent fatigue stress concentration. An abrasive waterjet was used to machine uniaxial dogbone fatigue specimens with specific surface quality from a rolled sheet of AISI 4130 CR steel. The surface texture resulting from machining was characterized using contact p...

mechanical properties of dissimilar weld joints between gost09ch16n4b (a martensitic stainless steel) and aisi 4130 thin sheets made by gas tungsten arc welding (gtaw) were studied using er410nimo and er100s-g filler metals in post weld heat treated conditions. heat treatment cycles consisted of austenitization at 900, 950 and 1000 °c for 1 h and this was followed by oil cooling and tempering a...

This work aims to investigate the microstructure and mechanical behavior of dissimilar API X80-AISI 4130 steel welded joints coiled tubing. The at weld interface AISI side results in a relatively lower toughness. HAZ has an obvious coarsening phenomenon. tensile tests show that deformation process joint is mainly controlled by two base materials: beginning X80 its end. Charpy impact toughness c...

Mechanical properties of dissimilar weld joints between GOST09ch16N4B (a martensitic stainless steel) and AISI 4130 thin sheets made by gas tungsten arc welding (GTAW) were studied using ER410NiMo and ER100S-G filler metals in post weld heat treated conditions. Heat treatment cycles consisted of austenitization at 900, 950 and 1000 °C for 1 h and this was followed by oil cooling and tempering a...

The aim of this paper was to study the effects of die life through shot peening treatments on AISI H13 steel, and tests were performed to study the influential parameters of the shot peening process. To evaluate the effects of microstructure and the die life of AISI H13 steel after steel shot peening processes, we conducted and evaluated roughness tests, micro hardness and wear tests, and SEM m...

In the present study, the effects of the boriding process on adhesion and tribological properties of AISI 310 steel were investigated. Boriding was performed in a solid medium consisting of Ekabor-II powders at 1123 and 1323K for 2 and 6 h. The boride layer was characterized by optical microscopy, the X-ray diffraction technique and the micro-Vickers hardness tester. The X-ray diffraction analy...
