[15A-T7-10] Evaluation of Binder Jet 3D Printed (BJT)M2 Tool Steel against the Wrought M2, Powder Metallurgy (PM) M2 and Laser Powder Bed Fusion (LBPF) Maraging Steel for Mould Application
キーワード：BJT, LBPF, PM
This work emphasizes the evaluation of BJTM2 Tool Steel against the Wrought M2, PM M2 and L LBPF Maraging Steel for Mould Application.LBPF process is followed to manufacture CC molds using maraging family alloys.The limitation in hardness (52 – 56 HRC) demands new material with high hardness (>60 HRC) to improve CC mould life.High speed steels (HSS) are the alternative options, but LBPF technology is not well suited for high-carbon ferrous alloys.BJT is capable of handling high-carbon alloys, additionally, it offers equiaxed grains with isotropic properties and no supports required during BJT printing.M2 – High-Speed Steel is known for well-balanced red hardness, wear resistance, and toughness. It is used in tempered condition with a hardness range of 58-62 HRC
