Charpy Verification Program: Reports Covering 1989-2002. Materials Reliable Series;Technical note

摘要

This is compendium of various studies on Charpy impact test procedure and specimen preparation variables in which NIST staff has participated in the past decade or so. Some of these studies had detail sufficient to make them worthy of peer review and publication in archival journals, others were just simple studies of one or two process parameters, and have never been published. However, all of them still contain information that is useful to those who produced reference grade verification specimens or have an interest in understanding how the various processing and procedure parameters affect absorbed energy. The collection serves as a single, archival source for these reports and the data that they contain. This Technical Note includes 23 presentations, grouped into sections on: (1) Overview and History; (2) Materials and Heat Treatment; (3) Specimen, Machine, and Procedure Effects; and (4) Statistical Evaluations of Charpy Impact Data.
