Title Mechanical Properties Investigation of Additive Manufactured Ti-6Al-4V Cellular Structure
Date 2018
Description Ti-6Al-4V is an alloy that has been developed to be used in medical implants due to its compatibility with the human body. Additive manufacturing technology has also become useful in constructing human bone design (marrow) from Ti-6Al-4V, imitating bone function. This research focuses on studying mechanical properties of Ti-6Al-4V using powder laser bed fusion (PLBF). This thesis describes the lattice structure for Ti-6Al-4V and discusses the design and the properties of the material based on tensile testing and other tests. This thesis focuses on understanding the mechanical properties of Ti-6Al-4V by presenting a literature review and comparing the structural strengths of the lattice and the full solid. Then, the research examines the powder comprising the fabricated specimen, the design that was chosen, and the parameters that affect the design mechanical properties in the results. Also, part of the discussion discusses heat affected zones (HAZ) comparing welding to additive manufacturing (AM) as a micro-weld. This section reveals some of the answers about the variability of mechanical properties in AM technologies, especially in PLBF. Lastly, microstructure images and CT scan images were analyzed through Image J. The image processing helps relate theoretical data and experimental results to quantitative data acquired from image processing. After compiling the analyses from the various sources, a design model was created to enhance the investigation of mechanical properties by giving visual evidence to support the conclusions.
