Phase transformation of a NiCrAlY coating alloy containing Re
The phase transformation of a NiCrAlY coating alloy containing Re was investigated by experimental observation and thermodynamic modelling in the temperature range from 800℃ to 1150℃.A phase change occurring at temperature between 1000℃~1050℃ was associated with a four-phase solid transformation, γ”-Ni3Al + α-Cr-→ γ-Ni + β-NiAl.The β-NiAl phase was observed to undergo a 3R martensite transformation in the specimen that was quenched from temperatures above 1000℃.The thermodynamic calculation performed with Thermo-Calc software and TTNi7 database agreed generally with experimental results.
