Study of Microstructure and Properties of 316L with Selective Laser Melting Based on Multivariate Interaction Influence by Jianfeng Sun, Lu Shen, Weiqiang Wang, Zhu Liu, Huaming Chen, Jieli Duan

“…As the selective laser melting 316L parts are constrained by multiple performance indexes, the study involves multivariate interaction influenced on the forming parameters such as the angle with the xz plane, the angle with the xy plane, laser power, scan speed, powder thickness, and hatching space on the indexes like tensile strength, density, and surface roughness with linear regression equations based on multiobjective optimization to obtain the best process parameters. The study results of microstructure performance of the formed 316L parts show that the angle with the xz plane has significant effect on the experiment indexes, while the layer thickness has the greatest effect on the indexes. …”

Effect of Ta Content on the Microstructure and Mechanical Properties of Laser Additive Manufactured Nickel-Based Superalloys by GUO Liangliang, WU Wenxing, YANG Tong, CHEN Pinghu, JIN Xuming, ZHU Tao, ZOU Xinchang, QIU Changjun

“…Alloys with low Ti/Al content exhibit insufficient strength，while those with high Ti/Al content are prone to cracking during laser additive manufacturing.To achieve a balance between high γ′ phase volume fraction and low crack susceptibility，this study proposed an alloy design strategy: appropriately reducing Ti/Al content while increasing Ta content based on the high-Ti/Al IN738LC alloy.Based on this design strategy，the microstructures and properties of four laser additive as-deposited samples with different Ta contents before and after solid solution treatment and aging treatment were studied.Results showed that with increasing Ta content，the as-deposited samples exhibited grain refinement and a higher γ′ phase fraction.The tensile strength and yield strength of both as-deposited and heat-treated samples increased as the Ta content increased，while their ductility decreased and cracking susceptibility intensified.When the mass fraction of Ta in the heat-treated samples reached 5%，η-phase precipitation occurred.At 7%Ta content，excessive η-phase formation led to brittle fracture surfaces in tensile specimens.Moreover，the sample with 5%Ta exhibited an optimal strength-ductility combination: at 25 ℃，yield strength of 962 MPa，ultimate tensile strength of 1 212 MPa，and elongation of 11.0%；while at 900 ℃，yield strength of 410 MPa，ultimate tensile strength of 486 MPa，and elongation of 6.1%.Generally，through optimization of Al，Ti and Ta contents，this study successfully developed a γ′-phase strengthened laser additive manufactured nickel-based superalloy.The alloy achieved an optimal balance between high γ′-phase volume fraction and low cracking susceptibility，demonstrating excellent comprehensive mechanical properties，and these findings provided valuable insights for the compositional design of laser additive manufactured nickel-based superalloys.…”
