Abstract In this study, a numerical model for the evolution of plastic anisotropy is investigated purpose stamping method design by Finite Element (FE) analysis and proved experimentally via process simulations cold-rolled austenitic stainless steel (AISI 304) sheet. The sheets described with fourth-order homogenous polynomial yield function modelling approach enhanced strain dependent material...

Steel ball indentation and scratch adhesion testing of hot filament chemical vapour deposited diamond films onto AISI type 316 austenitic stainless steel substrates using two different interlayer systems, namely chromium nitride and borided steel, have been investigated. In order to compare the adhesion of these films with that of a well-known and strongly adherent system, detailed adhesion tes...

Laser alloying is an effective method to form functional surface layers (coatings) on metallic materials, particularly stainless steels. Unique phase balance, dislocation substructure, and a possibility obtain gradient microstructures after laser slow down the degradation increase wear resistance. In this work, optimal parameters of their effects microstructure properties were investigated for ...

The very thin native oxide film on stainless steel, of the order of 2 nm, is known to be readily modified by immersion in aqueous media. In this paper, XPS and ToF-SIMS are employed to investigate the nature of the air-formed film and modification after water emmersion. The film is described in terms of oxide, hydroxide and water content. The preferential dissolution of iron is shown to occur o...

long–term stability and oxidation resistance of aisi 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. in this study the pack cementation method was employed to coat aisi 439 ferritic stainless steel with manganese. isothermal oxidation was conducted at 800 ºc for 200 hours in static air to investigate the role of coatin...

AISI D6 tool steel and 304 stainless are among the most widely used material in industry. However, this application field can still be expanded through coatings deposition. In regard, objective of work was to evaluate impact by cathodic cage technique using Hastelloy’s cage, on corrosion resistance these steels. Two treatment temperatures were compared. The samples characterized Optical Microsc...

The experimental and theoretical analysis of thermodynamical peculiarities heat flux at the fatigue crack tip during its propagation was made in presented work. goal is to elucidate relation between flow kinetic for different loading conditions. plane specimens with notch from stainless steel (AISI 304) were studied. There two types uniaxial one type biaxial loading. A dissipation measured by s...

In recent years, the need for eco-friendly machining processes has increased dramatically in order to limit excessive use of conventional cutting fluids, thereby reducing their negative effects on both environment and operator’s health. this context, environmental alternatives such as dry cutting, minimum quantity lubrication (MQL), nanofluid-assisted MQL have been demonstrated be effective ove...
