Additive manufacturing (AM) is a rapidly growing technology receiving global attention from several industrial sectors. The near net shape process has evolved significantly over recent years and is capable of fabricating fully dense structural parts with high potential for geometrical optimization that would not be possible with more traditional methods. However, understanding and characterizing the significant variance in the mechanical properties across the component due to the underlying transient microstructure is a fundamental research requirement. As such, traditional test approaches can be deemed unsuitable as it is difficult to extract representative test specimens which comply to relevant standards. Therefore, a suite of alternative experimental approaches capable of establishing the properties of geometrically representative microstructures and cross sections needs to be considered. Miniaturized mechanical test approaches are now widely exploited as an established means of obtaining useful mechanical property information from restricted material quantities and for components of limited dimension, providing a greater relationship to actual components than standard test techniques.
This webinar will highlight some of the recent research at Swansea University in realizing the benefits of several alternative experimental test methodologies in characterizing a variety of mechanical behaviors of different AM alloy systems. This includes small punch testing, which can be adopted to understand creep, tensile and fatigue type properties; shear punch tensile testing, which can be used to establish monotonic behavior and miniaturized tensile testing within a Scanning Electron Microscope (SEM) which can reveal localized damage under loading. Such methods can be used to understand the mechanical properties of highly localized regions, for remnant life assessment purposes, for quality control, ranking the performance of novel materials and where low volumes of stock material are available. Furthermore, the webinar will also discuss understanding scale effects of using test piece geometries of different dimensions.
