Physical and Mechanical Properties Testing for Demanding Environments

National Laboratory: 
Idaho National Laboratory
Characterization Class: 
Extreme Environment Testing
Mechanical Behavior of Materials

Idaho National Laboratory can perform testing related to creep-fatigue, stress relaxation, and in situ crack growth at elevated temperatures in vacuum or controlled chemistry/gas environments.

Capability Bounds: 

INL accommodates laboratory-scale test specimens of test-specific dimensions.

Unique Aspects: 

INL has a legacy of supporting a number of U.S. Department of Energy nuclear programs. From the materials validation standpoint, the ability to run physical property evaluations and mechanical testing under complex stress states and under nuclear quality assurance (NQA-1:2008/2009a) requirements has fostered a capability to collect, sort, and analyze property data from a number of materials systems that require strict quality control for ultimate validation.


Physical and mechanical properties testing in demanding environments can be conducted as a collaborative or subcontracted effort with INL researchers.
