Tribological Behaviour of Fe-Al Intermetallic Compound Coated Carbon Tool Steel
The use of Fe-Al intermetallic compound coatings has been investigated in order to improve the tribological behaviour of carbon tool steel. The coatings were formed by a pack cementation process and subsequently diffusion annealing at 900˚C in an argon controlled atmosphere. The optimum diffusion time was selected on the basis of optimum thickness and tribological behaviour. The microstructure...

متن کاملREACTION KINETICS OF THE FORMATION OF INTERMETALLIC Fe – Zn DURING HOT - DIP GALVANIZING OF STEEL
P. Pokorny, J. Kolisko, L. Balik – Czech Technical University – Klokner Institute, Prague, Czech Republic P. Novak – Institute of Chemical Technology, Prague, Czech Republic This review article mainly describes the composition of intermetallic Fe Zn, i.e. zeta (ζ), delta (δ1k + δ1p), gamma1 (Γ1) and gamma (Γ) on galvanized steel during low temperature galvanization (t ~ 450 °C). It gives detail...
متن کاملFracture toughness of graphene.
Perfect graphene is believed to be the strongest material. However, the useful strength of large-area graphene with engineering relevance is usually determined by its fracture toughness, rather than the intrinsic strength that governs a uniform breaking of atomic bonds in perfect graphene. To date, the fracture toughness of graphene has not been measured. Here we report an in situ tensile testi...
متن کاملElectron Diffraction Study on Fe–Zn intermetallic Phase of a Galvannealed IF Steel Sheet
In order to investigate the structure of Fe–Zn phase in a commercial galvannealed IF steel sheet, the electron diffraction and composition of phase in a commercial galvannealed IF steel sheet were studied by transmission electron microscope (TEM) and X-ray energy dispersive spectroscopy (EDX). The cross-sectional TEM specimen was prepared using focused ion beam (FIB) technique which was also in...
