| Abstract Scope |
Advanced indentation testing provides high-throughput, location specific mechanical property measurements. This is critical for additive manufacturing, which requires rapid characterization tools to speed the development of new processes and materials and local characterization tools to quantify location specific process-structure-property relationships that frequently exist in AM parts. Three types of indentation tests (Berkovich micro-indentation, spherical micro-indentation, and small punch testing) were used on a variety of AM alloys with varying microstructures. The results are critically compared against tensile properties. A framework for high-throughput experiments will be discussed along with measurement science needs for advanced indentation testing characterization of AM alloys. |
