Solidification behaviour of a high chromium nickel base alloy weld deposited metal
Source abstract
Abstract
The solidification behaviour including microsegregation and secondary phase formation of a high chromium nickel base alloy weld deposited metal was examined with optical microscopy, scanning electron microscopy and transmission electron microscopy. Microsegregation potential of major alloying elements in the weld deposited metal was investigated. The microconstituents formed during solidification were identified to be TiC and γ/Laves eutectic constituent. Most γ/Laves eutectic constituents were located at the dendrite interstices due to the microsegregation of Nb, Mo and Si. The volume percent of γ/Laves constituent was predicted by using Scheil equation, and there was a reasonable agreement between the predicted and measured value. Last, two possible solidification paths added to the γ-Nb-C pseudoternary solidification diagram were proposed to analyse the solidification sequence of the new high chromium nickel base alloy.
