Abstract Scope |
The objective of this talk is to explore how to effectively bridge length scales in mechanical testing standards, to accelerate nuclear materials qualification. In practice, nuclear materials surveillance and qualification requires adherence to established ASTM standards. Standardized mechanical tests inherently bridge length scales by assessing the embrittlement of a heavy component having dimensions ~meters, using a specimen with dimensions ~cm. Research advancements over the past decade have pushed dimensional limits, such that some elasto-plastic quantities can be ascertained from nanomechanical test specimens ~nano-micrometers. Such nanomechanical tests offer tremendous potential for accelerating nuclear alloy development by testing small material volumes readily accommodated in-reactor. But standardizing nanomechanical tests is a long overlooked challenge with few precedents. This talk will review recent research in bridging the length scales from nano to standardized "bulk" specimens. We will then consider how we can translate research advancements into a standards framework. |
