Abstract

Abstract In this work, the possibility of manufacturing complex-shaped components from a carbon-martensitic hardenable cold-work steel (1.2379; X153CrMoV12; D2) is investigated. For this purpose, cube-shaped samples with an edge length of 10 mm were produced using the fused-filament fabrication process, which were post-compacted after solvent debinding by supersolidus liquid-phase sintering. Using the knowledge of liquid phase volume content as a function of temperature, supersolidus liquid phase sintering experiments were performed. The microstructure formation process was characterized by electron microscopy and X-ray diffraction. The microstructure and hardness of the processed samples were compared in the heat-treated condition with the properties of the same steel 1.2379 (X153CrMoV12; D2) in the as-cast, deformed and heat-treated condition. The results demonstrate effective post-densificationc close to theoretical density of cold-work tool steel samples fabricated by fused-filamet fabrication using supersolidus liquid-phase sintering at 1280 °C. The defect-free microstructure in the heat-treated state is characterized by a martensitic matrix and eutectic Cr-rich M7 C3 and small amounts of V-rich MC carbides. The hardness of the annealed Supersolidus liquid phase sintering samples are 681 ± 5 HV10, which is above the level of the reference material 1.2379 (629 ± 7 HV10) in the as-cast, formed and heat-treated condition.

原子扩散添加剂制造莱氏体冷加工工具钢的超固相液相烧结和热处理*
摘要:本文研究了用碳-马氏体可淬冷作钢(1.2379;X153CrMoV12;D2)被调查。为此,采用熔融长丝制造工艺制备边缘长度为10 mm的立方体样品,并在超固相烧结溶剂脱脂后进行后压实。利用液相体积含量作为温度函数的知识,进行了超固液相烧结实验。通过电子显微镜和x射线衍射对其微观结构的形成过程进行了表征。将热处理后试样的显微组织和硬度与同一钢1.2379 (X153CrMoV12;D2)在铸态、变形和热处理状态下。结果表明,在1280°C超固相烧结熔丝法制备的冷作工具钢试样的后密度与理论密度接近。热处理态无缺陷组织为马氏体基体和共晶富cr的M7 C3以及少量富v的MC碳化物。退火后的超固相液相烧结样品的硬度为681±5 HV10,高于标准材料在铸态、成形态和热处理态的硬度1.2379(629±7 HV10)。
