Auf zwei Almen wurde der Einsatz von GPS-basierten Trackingsystemen an acht Jungrindern (Herdengröße: 36 Tiere) über einen Almsommer untersucht. Die Trackingsysteme wiesen eine statische Genauigkeit im Median zwischen 7,5 und 11,2 m auf. Der Anbringungsort des Systems am Hals (dorsal vs. lateral, getestet an einem Tier) hatte einen signifikanten Einfluss auf die im Median empfangene Anzahl an D...

This study deals with magnetic Barkhausen noise emission produced by strain-induced martensite generated during shot peening of austenitic AISI 304 stainless steel. The transformation from the paramagnetic to ferromagnetic state and corresponding birth domain structure are important respect irreversible motion walls emission. is investigated explained residual stress as well microstructure expr...

Photon Induced Positron Annihilation (PIPA) and related portable technologies’ have demonstrated their ability to nondestructively quantify shot peening/surface treatments and relaxation effects in single crystal superalloys and steels with a single measurement as part of a National Science Foundation SBIR program. PIPA measurement of surface treatment effects provides a demonstrated ability to...

Abstract In this study, the effect of kinetic energy shot peening process on microstructure, mechanical properties, residual stress, fatigue behavior and stress relaxation under loading AISI 316L stainless steel were investigated to figure out mechanisms crack initiation failure. Varieties experiments applied obtain results including microstructural observations, measurements hardness, roughnes...
