Steel Cruciform Sample with Nitrided Arms Achieves Higher Plastic Strain in the Gauge Region

open access: yesApplied Sciences, 2022
This paper describes a novel solution to increase plastic strain in the gauge region of a cruciform sample during a forming limit test. A nitriding procedure was used to increase the strength of the arms of the specimen and at the same time enabled ...
