摘要

为了改善不锈钢的微观结构、表面形态、成型性和应力响应，研究了线弧添加沉积不锈钢的机械和热加工工艺。显微镜有助于确定加工条件，从而使已形成的柱状微观结构得以充分再结晶。结合拉伸试验中的应变加载路径、形貌和断裂图显示，机械加工包括减薄 20%的厚度，然后在 1100 °C 下退火 4 小时，可消除各向异性，并将断裂成形极限提高 30%。这项工作为巩固线弧快速成型制造与金属成型的混合，以替代传统制造迈出了一步。

Mechanical and thermal processing of wire-arc additively deposited stainless steel

Mechanical and thermal processing of wire-arc additively deposited stainless steel is investigated with the purpose of improving its microstructure, surface morphology, formability, and stress response. Microscopy helps identifying the processing conditions that permit full recrystallization of the as-built columnar microstructure. Combination with strain loading paths, topography and fractography in tensile tests show that mechanical processing consisting of 20 % thickness reduction followed by annealing at 1100 °C under 4 h eliminates anisotropy and increases the fracture forming limits by 30 %. The work is a step forward to consolidate the hybridization of wire-arc additive manufacturing with metal forming as an alternative to conventional manufacturing.
