Microstructural effects on the rotating bending fatigue behavior of Ti-6Al-4V produced via laser powder bed fusion with novel heat treatments

April 30, 2024
Author(s)
Nicholas Derimow, Jake Benzing, David Newton, Chad Beamer, Ping Lu, Frank DelRio, Newell Moser, Orion Kafka, Ryan Fishel, Lucas Koepke, Chris Hadley, Nik Hrabe
The rotating bending fatigue (RBF) behavior (fully reversed, R = -1) of additively manufactured (AM) Ti-6Al-4V alloy produced via laser powder bed fusion (PBF-L) was investigated with respect to different microstructures achieved through novel heat

NIST Software Package for Obtaining Charpy Transition Curves

May 11, 2021

Enrico Lucon, Jolene D. Splett, Amanda Koepke, David Newton
NIST has developed a software package that allows users to fit test results obtained from Charpy or toughness tests as a function of test temperature, thereby obtaining so-called transition curves. Non-linear fitting is available for five regression models

Decision Tree for Key Comparisons

Author(s)
Antonio Possolo, Amanda Koepke, David Newton, Michael R. Winchester
This contribution describes a Decision Tree intended to guide the selection of statistical models and data reduction procedures in key comparisons (KCs). The Decision Tree addresses a specific need of the Inorganic Analysis Working Group (IAWG) of the
