摘要
热等静压能够消除材料内部缺陷和残余应力,提高力学性能,作为金属3D打印构件后处理的重要手段,越来越受到国内外广泛关注并得到迅速发展。综述了近期国内外科研人员针对多种材料的3D打印构件实施热等静压后力学性能变化,阐述了性能提高的主要原因,进而为热等静压处理3D打印构件提出了一些建议。
Hot isostatic pressing can eliminate internal defects and residual stress of materials and improve mechanical properties.As an important means of post-treatment for metal 3D printed components,it has attracted more and more attention and developed rapidly at home and abroad.The recent progress in improving mechanical properties of 3D printed components by hot isostatic pressing is reviewed,the main reasons for the improvement of mechanical properties are described,and some suggestions for hot isostatic pressing 3D printed components are put forward.
