【摘要】 对FGH4096合金盘件的双组织热处理进行了数值模拟和试验验证:数值模拟结果表明,通过选定合适的工艺参数,可实现盘件不同部位的温度梯度。在数值模拟的基础上,进行了盘件双重组织热处理,获得了轮缘部位为5~6级晶粒度,轮毂部位为10级晶粒度,辐板区域组织平缓过渡的双晶粒组织涡轮盘件。更多还原

【Abstract】 By means of numerical simulation and experiment,dual microstructure heat treatment(DMHT) process is simulated and corresponding experimental DMHT processes have been performed.The numerical simulation showed that DMHT processes is reasonable for dual microstructure turbine disk production.Under certain conditions,temperature gradient for different zones can be acquired for FGH4096 PM superalloys turbine disk.Based on the numerical simulation results,A experimental DMHT processes are performed,the experimental result showed that the pancake rim zone grain growth is noticeable,the bore zone grain size of pancake is still fine,the hub zone grain size is between rim zone and bore zone.The numerical simulation and experimental result proved that DMHT process is feasible for FGH4096 superalloy Dual microstructure turbine disk production.更多还原
