However, due to different strain hardening behaviors of two phases in the duplex stainless steel, the deformation of the two phases is uneven and the coordination is poor, so that the heat processing difficulty of the duplex stainless steel is high, the defects of edge and surface cracks and the like are extremely easy to occur during processing, and the expansion of the duplex stainless steel in the aspect of preparing complex parts is severely restricted. The selective laser melting (SELECTIVE LASER MELTING, SLM) technology is an important branch in the 3D printing technology, can well solve the forming problem of complex parts, builds a three-dimensional model based on a computer system, adopts laser melting metal powder, and accumulates and forms solid parts layer by layer from bottom to top. The SLM technology has the advantages of direct forming, no need of a die, capability of manufacturing high-precision parts and the like, endows materials with excellent mechanical properties, and is widely applied to aerospace, biomedical, power energy and related fields.
SLM-former performance is greatly affected by process parameters such as laser power, scan speed and scan pitch. The process parameters are unreasonably selected, the defects of insufficient powder melting, discontinuous melt channel, splashing of melt and the like can occur in the material, and the mechanical properties of the material are deteriorated while the density of the sample is reduced. Therefore, reasonable technological parameters are selected, so that the compactness and mechanical properties of the sample can be effectively improved, and the high-quality duplex stainless steel is prepared. However, no theory or method has been found to accurately predict the density and mechanical properties of the test sample by the process parameters.
Therefore, a method capable of effectively predicting the compactness and mechanical properties of the sample through the process parameters is needed, so that the compactness and mechanical properties of the sample under different process parameters are predicted, a reasonable process parameter range is determined, and theoretical reference is provided for preparing the high-performance duplex stainless steel.
