Precise tailoring of manufacturing processes for superalloys:strategy,methodology and validation
摘要
Abstract
As a critical strategic material for aero-engines and industrial gas turbines,the composition/process design,optimization and process control of superalloys remain at the core of industry concerns.The present work focuses on addressing practical challenges in the development and production of superalloys and their components.It identifies key influencing factors in typical processes within the manufacturing workflow and employs a combination of advanced characterization techniques such as synchrotron radiation and high-throughput experimental methods.This integrated approach enables the design and optimization of critical process parameters for superalloy manufacturing,thereby providing foundational support for enhancing process technology,product performance,research and development efficiency,and reducing costs.Taking representative manufacturing processes involving liquid-solid and solid-solid phase transformations as examples,we explore precision tailoring strategies and validation methods for key stages including master alloy melting/remelting,synergistic particle size/morphology control in gas atomization,shrinkage porosity control during casting solidification,powder storage/desorption treatments,powder consolidation through hot isostatic pressing(HIP)and heat treatment procedures.In addition,optimal usage conditions are investigated for auxiliary materials or consumables integral to superalloy production,particularly ceramics,isothermal forging dies and brazing repair materials.Notably,the research on process tailoring reveals significant phenomena:(1)the impact of oxygen existence forms in cast and powder metallurgy alloys;(2)the influence of the initial microstructural state of alloys on the phase transformation temperature during HIP consolidation and heat treatment;(3)the formation and control of abnormal phases and defects in cast,powder metallurgy and additive manufacturing alloys,along with repair materials for brazing and ceramic refractories.The aforementioned findings establish a theoretical foundation for optimizing and tailoring superalloy process parameters and achieving precise manufacturing control,while also providing feasible technical pathways for industrial implementation.关键词
