New NIST Acquisition System for Reading Charpy Machine Encoders

November 13, 2023
Author(s)
Enrico Lucon, John S. Quintavalle, Damian Lauria
A new acquisition system was developed at NIST for reading angle values from the digital encoders of the three Charpy reference machines in Boulder, Colorado. The associated LabView software provides the conversion from encoder angles to absorbed energies

Matthew Connolly, May Ling Martin, Zack Buck, Newell Moser, Enrico Lucon, Damian Lauria, Peter Bradley, Andrew Slifka, Robert Amaro
This report details the results of Phase I of the DOT/PHMSA sponsored work on "Determining Steel Weld Qualification and Performance for Hydrogen Pipelines". In this work, the goals of Phase I were 1) to perform a literature review of steel weld

Fracture Toughness Tests at 77 K and 4 K on 316L Stainless Steel Welded Plates

July 29, 2022
Author(s)
Jake Benzing, Nicholas Derimow, Enrico Lucon, Dash Weeks
In the framework of a collaborative project between ASME, NASA, and NIST, quasi-static fracture toughness tests have been performed at liquid nitrogen temperature (77 K, or -196 °C) and liquid helium temperature (4 K, or -269 °C) on weld specimens

KEY COMPARISON - Instrumented Charpy tests on low- and high-energy specimens

February 18, 2022
Author(s)
Enrico Lucon, Renato Reis Machado
This report describes a CIPM Key Comparison through the SIM/MWG-7 organization, concerning instrumented impact testing of low-energy (20 J) and high-energy (100 J) Charpy V-notch specimens. In this Comparison, various instrumented and non-instrumented data
