摘要
综述了激光增材制造镍基高温合金Mar-M247和CM247LC中裂纹的类型、形成机制以及抑制方法的研究现状。从参数优化、外场辅助以及材料开发等方面对激光增材制造无裂纹Mar-M247和CM247LC合金的发展趋势进行了综述,指出采用更为优化的参数统计方法加速工艺筛选、设计更具灵活性的预热方式以及人工智能赋能新型打印材料开发可能是该领域重要的发展方向。
The current research status on types,formation mechanisms,and suppression methods of cracks in laser additive manufactured Mar-M247 and CM247LC superalloys was comprehensively reviewed.The development trend of crack-free Mar-M247 and CM247LC alloys by laser additive manufacture was prospected from aspects of parameter optimization,field assistance and material development.The application of advanced parameter statistics to accelerate process screening,the design of more flexible preheating methods,and the development of novel printing materials enabled by artificial intelligence can be an important development direction.
