The purpose of this research is to laser cladding of stellite6 and stainless steel 17-4PH powders on the substrate of stainless steel 17-4PH, and investigate its solidification microstructure. The results showed that the microstructure of the stellite6 cladding has a cobalt solid solution ground phase with an FCC structure and Cr7C3 and Cr23C6 carbides. Also, the values ​​of the primary dendrit...

As the structure of biofilms plays a key role in their resistance and persistence, this work presents for the first time the numerical characterization of the temporal evolution of biofilm structures formed by three Listeria monocytogenes strains on two types of stainless-steel supports, AISI 304 SS No. 2B and AISI 316 SS No. 2R. Counting methods, motility tests, fluorescence microscopy and ima...

Abstract: The investigation is carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials: the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steel 310. This paper describes the effects of aging treatment on the joint. The compara...

Transient liquid phase bonding of  UNS S32750 super duplex stainless steel to AISI 304 austenitic stainless steel using BNi-2 interlayer was carried out at 1050 oC for 45 min. Microstructure analyses of the joint were carried out using optical microscopy, scanning electron microscopy and energy-dispersive X-ray spectroscopy. Microhardness indentation and shear strength test were performed to as...

Abstract The "Gold Dust Defect" affects the surface quality of AISI 430 ferritic stainless steels. However, there is a very limited number studies focusing on it. To better understand its nature, we have combined several techniques, such as x-ray photoelectron spectroscopy, atomic force microscopy, and transmission electron in order to extract maximum structural compositional information. Our r...

It is well known that during tensile testing, a part of the mechanical work done on the specimen is transformed into heat energy. The rate of rise and maximum temperature attained depends on the nature of material, its deformation behaviour and test conditions. This paper highlights the application of thermography for characterising various stages of tensile deformation in AISI type 316 stainle...
