X-ray Diffraction Study of Directional Solidification Ledeburite

Abstract

Directionally solidified sample of Fe-Fe3C eutectic alloy were produced under an argon atmosphere in a vacuum Bridgman-type furnace to study the eutectic growth with ν = 167 μm/s pulling rate and constant temperature gradient G = 33.5 K/mm. Since how the growth texture of eutectic cementite is related to its growth morphology remains unclear, the current study aims to examine this relationship. The technique such as X-ray diffraction, have been used for the crystallographic analysis of carbide particles in white cast irons.

Characterization the microstructure of pulsed Nd:YAG welding method in low frequencies; correlation with tensile and fracture behavior in laser-welded nitinol joints

“…As can be seen, x-ray diffraction pattern of base metal is different from that of weld metals; diffractions in pattern corresponding to fracture surfaces have been concentrated on a fewer number of peaks. This is one of the features of directional solidification [19]. Therefore, this difference justifies directional solidification observed in microstructure of principle plane and fracture surface (figures 6 and 10).…”

Effect of Heat Treatment on Formation of Al-Al₃Ni Hypereutectic Alloys

“…Depending on the initial concentration of constituents, hypo-eutectic, eutectic or hyper-eutectic alloy can be produced [2]. The resulting eutectic commonly give rise to lamellar or fibrous structures [3,4]. A theoretical explanation of its growth was described in 1966 by Jackson and Hunt [5].…”
