Fatigue Properties of Nodular Cast Iron at Low Frequency Cyclic Loading

open access: yesArchives of Metallurgy and Materials, 2017
Three melts of ferrite-pearlitic nodular cast iron with different charge composition were used for fatigue tests. Wöhler fatigue curves and fatigue strength were obtained, and microstructure and fracture surfaces were investigated.

Creep-fatigue life assessment of cruciform weldments using the linear matching method [PDF]

open access: yes, 2013
This paper presents a creep-fatigue life assessment of a cruciform weldment made of the steel AISI type 316N(L) and subjected to reversed bending and cyclic dwells at 550C using the Linear Matching Method (LMM) and considering different weld zones.

Deformation and fatigue behaviors of carburized automotive gear steel and predictions [PDF]

open access: yesFracture and Structural Integrity, 2016
The fatigue behavior of carburized components such as automotive transmission gears is very complex due to hardness and microstructure difference, residual stresses and multi-axial stress states developed between the case and the core.

Effect of micro-arc oxidation coating defects on fatigue property of Al alloy substrate

open access: yesJournal of Materials Research and Technology, 2022
Ambiguous fatigue failure mechanism of micro-arc oxidation (MAO) coated samples was an urgent issue to be solved. In this paper, the influence mechanism of coating defects on the fatigue property of the samples with thin MAO coating was studied. Based on

Fatigue characteristics of sand-cast AZ91D magnesium alloy

open access: yesJournal of Magnesium and Alloys, 2017
The fatigue characteristics of the AZ91D-T6 alloy samples taken from engine blocks have been investigated at 20 °C and elevated temperature (150 °C). The fatigue strength and cyclic stress amplitude of the alloy significantly decrease with the increase ...

Data demonstrating the effects of build orientation and heat treatment on fatigue behavior of selective laser melted 17–4 PH stainless steel

open access: yesData in Brief, 2016
Axial fully-reversed strain-controlled (R=−1) fatigue experiments were performed to obtain data demonstrating the effects of building orientation (i.e. vertical versus horizontal) and heat treatment on the fatigue behavior of 17–4 PH stainless steel (SS)
