FSW material flow and phase transformation were studied at the interface of dissimilar welding of Al 6013 to Mg. Defect free butt weld was obtained when aluminum and magnesium test plates were placed in the advancing side and retreating side respectively, and the tool was placed 1 mm off the weld centerline into the aluminum side. In order to understand how the materials flow during FSW, steel ...

Intermetallic compounds are increasingly being expected to be utilized in tribological environments, but to date their implementation is hindered by insufficient ductility at low and medium temperatures. This paper presents a novel multiphase intermetallic alloy with the chemical composition of Mo-40Ni-13Si (at %). Microstructure characterization reveals that a certain amount of ductile Mo phas...

Abstract: Two different coating microstructures of Ni-50Cr alloy were obtained on a stainless steel substrate by changing combustion characteristics of a high velocity oxy-fuel (HVOF) process and the size distribution of feed powder during coating process. Use of the finer feed powder and leaner fuel in oxygen/fuel ratio (i.e. using a ratio much less than stoichiometric ratio) led to formati...

abstractin this paper, we investigate effect of fe–intermetallic compounds on plastic deformation of closed-cell composite aluminum foam as filler of thin-walled tubes. however, deformation of the aluminum foam-filled thin-walled tubes as crushed-box will be presented in part (ii). composite foams of alsi7sic3 and alsi7sic3-(fe) as closed cell were synthesized by powder metallurgy foaming metho...

In this paper, the reactive diffusion in Ni80C20r?Ti ternary system is discussed at 1173K. The couple was prepared and annealed for 100 h. two intermetallic phases two-phase zones occurred, namely: Ti2Ni, TiNi, TiNi+Cr, TiNi3+Cr. Based on experimental results (molar fractions, thicknesses of phases), intrinsic coefficients all components each phase were numerically approximated. Wagner method u...

Multiple primary and eutectic intermetallic compounds (IMCs) often form during the solidification of multicomponent magnesium alloys. Here, we comprehensively explore formation in Mg-4Sn-3Al-1.5Zn-0.6Mn (wt%) as-cast alloy, comparison with Mg-3Al-1Zn-0.3Mn, to better understand Mg 2 Sn complex multiphase how it affects other IMCs. Various IMCs formed at different stages solidification: τ-AlMn A...
