Abstract

With time, the benefits of additive manufacturing have become firmly established in the domain of medical technology. The high degree of design freedom and precision afforded by additive manufacturing enables the production of implant components that are precisely tailored to individual requirements and based on patient-specific data. In addition to the advantages, the production of such components presents process-related material science challenges. One such challenge of this manufacturing process is the residual stresses due to the occurring phase transformation during the rapid process-related cooling rates. These stresses can lead to component deformation and impair the mechanical load-bearing capacity of the component, leading to accelerated fatigue. This aim of this study is to analyse the various influences of manufacturing and machining processes such as heat-treatment or application-related stress on the residual stress state of additively manufactured components based on titanium alloys.

制备工艺及动态测试对增材制造Ti-6Al-4V晶格结构试样残余应力状态的影响

随着时间的推移，增材制造的好处已经在医疗技术领域得到了牢固的确立。增材制造提供的高度设计自由度和精度使植入物组件的生产能够根据个人需求和患者特定数据进行精确定制。除了这些优势之外，这些部件的生产还提出了与工艺相关的材料科学挑战。这种制造工艺的一个挑战是由于在快速的工艺相关冷却速率期间发生的相变而产生的残余应力。这些应力会导致构件变形，损害构件的机械承载能力，导致构件加速疲劳。本研究的目的是分析制造和加工工艺（如热处理或应用相关应力）对钛合金增材制造部件残余应力状态的各种影响。
