Results of nanoindentation test to calculate residual stress in an eyelet of undercarriage drag strut after laser treatment
Open Research DataIn order to determine the residual stress in the laser-processed an eyelet of undercarriage drag strut, a nanoindentation test was performed before and after stress relief annealing. For this purpose, after the hardness test, the sample was subjected to stress relief annealing at 270 °C for 2 hours. Annealing was performed in a vacuum furnace. Hardness...

Results after grinding C45 steel
Open Research DataThe database contains results from nanoindenter, scanning microscope and also X-ray diffractometer. To determine the residual stresses and the size of the crystallites in the ferrite grains in the grinded surface layer, the Williamson Hall analysis of the X-ray diffraction patterns was performed. XRD diffraction patterns were also used to perform a...
