Tensile Properties of Ferrite-austenitic Welded Joint
Very often, in order to optimized welded constructions, some of their parts are made of heterogeneous steels. For example, microalloyed steels are in use for cars chassis making and high alloyed steels for different constructions making. From that reason, it’s not rare to find welded joints between ferrite microalloyed and austenitic highalloyed steels. As a rule, these joints are welded by usi...
متن کاملEvaluation of microstructure and mechanical properties of friction stir welded copper / 316L stainless steel dissimilar metals
In the present research, friction stir welding (FSW) process was used for butt joining of pure copper plate to 316L stainless steel plate. Mechanical properties and microstructural characteristics of the joint were evaluated by microhardness and tensile tests as well as optical and scanning electron microscope (SEM). It was found that microstructure of the weld nugget (WN) has fine grains where...
متن کاملInfluence of rotational speed on the development of microstructure in a friction stir welded 304 austenitic stainless steel
Friction stir welding was conducted on AISI 304 austenitic stainless steel sheet with dimensions of 100 mm × 100 mm × 2 mm. The FSW was performed at a welding speed of 150 mm/min and rotational speeds of 400 and 800 rpm. The results showed that high frequency of low angle grain boundaries (LAGBs) were formed through dynamic recovery in the thermo-mechanically affected zone (TMAZ). Higher amoun...
متن کاملLow-Temperature Carburization of Austenitic Stainless Steels
LOW-TEMPERATURE CARBURIZATION is a gaseous carburization process performed at atmospheric pressure, at temperatures where the kinetics of substitutional diffusion are very slow. Low-temperature carburization hardens the surface of austenitic stainless steels through the diffusion of interstitial carbon, without the formation of carbides. The surface must be activated, by modification and remova...
متن کاملDevelopment of Alumina-Forming Austenitic Stainless Steels
This paper presents the results of the continued development of creep-resistant, alumina-forming austenitic (AFA) stainless steel alloys, which exhibit a unique combination of excellent oxidation resistance via protective alumina (Al2O3) scale formation and high-temperature creep strength through the formation of stable nano-scale MC carbides and intermetallic precipitates. Efforts in fiscal ye...
