The Grain Growth of Austenitic Model Steel during Fast Heating
Year: 2014
Type: article
Abstract: The metallographic observation, thermo-simulation test and quantitative statistics were used to investigate the grain growth on different parts of the samples for Fe-40Ni-Ti alloy. The experiment results demonstrate that: near the center of the sample corresponding to the summit point of the temperature, the grain grows rapidly in 5s when the temperature reaches 1350°C, whose size is about 180μm; While the grain size of parent metal and HAZ (4mm to the welding line) remains nearly unchanged, whose size is about 80μm. The size of TiN particles in the welding line is fine than that of the parent metal obviously and the hinder to the grain boundaries can be observed. With the aid of Fe-40Ni-Ti alloy, the austenitic grain growth in the steel can be simulated.
