Abstract The present paper focuses on evaluating the bonding strength interfaces between contact materials such as AISI 304L and Ti-6Al-4V via. friction welding (FW). Experimental tests are performed by considering process parameters time, rotational speed pressure, mechanical properties were evaluated. of 1800, 1600, 2100, 2300 2500 rpm considered in study. response surface methodology (RSM) i...

Pack-boriding was applied to AISI 304L stainless steel material at temperatures of 850, 900 and 950 °C for 2, 4 6 hours with microwave hybrid heating method. The morphology the boride layer formed on surface samples examined by optical microscope, phases in were determined XRD. analysis adhesive strength substrate carried out Daimler-Benz Rockwell-C adhesion test. tests repeated least 3 times e...

The corrosion resistance of type 304L and 316 austenitic stainless steels in 2M H2SO4 at 0-1.5%NaCl concentrations was studied through potentiodynamic polarization technique and optical microscopy analysis. The corrosion rate, pitting potential, passivation potential and surface morphology of both steel where significantly altered by the Clion concentration, alloy composition and metallurgical ...

The article presents results of comparative A-TIG welding tests involving selected unalloyed and fine-grained steels, as well high-strength steel WELDOX 1300 austenitic stainless AISI 304L. involved the use single ingredient activated fluxes (Cr2O3, TiO2, SiO2, Fe2O3, NaF, AlF3). In cases carbon low-alloy revealed that greatest increase in penetration depth was observed steels which had been de...

This paper evaluates the suitability of X-ray diffraction (XRD) technique to characterize phase transformation during metal forming metastable austenitic steel AISI 304L. Due plastic deformation, from γ-austenite into α′-martensite occurs. The XRD peaks at specific 2θ angles give information about amount. Analyses results with different characterization techniques such as microscopic analysis, ...
