Abstract Scope |
Time-dependent properties such as creep properties are critical for structural materials’ applications in certain energy sectors such as nuclear. Due to the unique microstructures, adopting additively manufactured (AM) alloys requires new creep data to be collected before qualification and implementation. In this talk, a set of creep data on AM 316L stainless steel manufactured by the laser powder bed fusion will be presented, as well as the deformation microstructures characterized by optical and electron microscopy techniques. In addition, synchrotron high-energy x-ray tomography has been used to measure the pores and/or cracks inside the test specimens before and after deformation. New developments in tomography data analysis, using advanced computing algorithms including convolutional neutron networks, have been implemented to directly reduce raw detector data into explicit pore/crack shape representations for quantitative measurements. Together, the microstructural information provided a rationale for the creep performance of the AM 316L stainless steel. |
