摘要: Abstract The microstructure–property relationship of deformed parts has been becoming very critical, especially for aerospace components. design manufacturing process to achieve the unique and required microstructure property is thus critical. For turbine disc, fine bore region disc provide high tension strength fatigue resistance at low temperature (420–650 °C). coarse also needed its rim possess excellent rupture life crack growth (>760 °C). A heat treatment method was developed produce gradient from regions. In this study, (GTHT) carried out on FGH 4096 superalloys under conditions (1080 °C260 °C/30 min, AC) (1140 °C300 °C/30 min, AC), two structural-gradient-materials (SGMs) were obtained. SGM produced by GTHT condition equiaxed grains flatted grains. between microstructures, a transition found. dual-size material successfully fabricated AC). grain size approximately 40 μm, while about 4 μm. microstructural mechanisms SGMs during hot working are identified in research. Furthermore, potential application dual-property disc.
