EFFECTS OF SHOT PEENING ON HARDNESS OF 18CRNIMO7-6 STEEL BASED ON FINITE ELEMENT ANALYSIS

open access: yesJixie qiangdu, 2022
So far, most of the numerical studies on shot peening are limited in the effects of shot peening parameters on the residual stress and surface morphology. There is still lack of numerical research on shot peening parameters on the hardness.

Resilienza alle basse temperature di diversi acciai cementati e temprati [PDF]

open access: yes, 2014
In letteratura tecnica sono state numerose le pubblicazioni relative al comportamento degli acciai dacementazione alle sollecitazioni per urto, soprattutto con riferimento agli ingranaggi sottoposti a “impactfatigue”, a temperatura ambiente (1-2-3-4-5-6)

HEAT AFFECTED ZONE MICROSTRUCTURE OF WELD JOINT PREPARATION IN ARTIFICIAL MANNER [PDF]

open access: yes, 2019
This paper presents two possibilities of martensitic (fine grain and coarse grain) microstructure preparation. These microstructures are present as sub-zones in the heat-affected zone of welded joints, but due to the narrow region of HAZ in a real weld ...

Hybrid methodology development for lubrication regimes identification based on measurements, simulation, and data clustering [PDF]

open access: yes
The lubrication regimes of a laboratory scale journal bearing were analysed with wide band acoustic emission (AE) measurements. The analysis was supported by data-based clustering of AE data. Digital twin of the journal bearing was generated with Simpack
