This study considers how the fatigue behavior and probabilistic properties of SAE1055 steel are related to its hardness level. SAE1055 steel was heat-treated using induction hardening. Five types of specimens were prepared (A:base material, B:through hardened material with HV390, C:through hardened material with HV510, D:through hardened material with HV700, and E:surface hardened
Effect of Contact Pressure and Cyclic Stress Amplitude on Abstract:The effect of contact pressure on fretting fatigue in quenched and tempered 45-carbon steel is studied. With an increase in contact pressure, fretting fatigue life is decreased quickly at low contact pressures; however it almost unchanged at high contact pressures. With an increase in cyclic stress amplitude, fretting fatigue life decreased.
The low-cycle fatigue results of three heats of Type 304 stainless steel have been ob-tained at 593°C under selected cyclic-loading conditions. The results are compared with those generated for a reference heat of steel for which extensive low-cycle fatigue data are available. Observation of the microstructures of specimens in the pretest condition after a given heat treatment and examination
Experimental Investigation on Static and Fatigue Behavior The paper aims to evaluate the fatigue behavior and its probabilistic properties in welded SM490A steels, which is utilized in high speed train, under low temperatures.
Experimental investigation on static and fatigue behavior Mar 01, 2009 · The probabilistic properties of fatigue life are investigated through P-S-N (probabilistic S-N) approach and the predicted results are well in conformance with the experimental results. Also, the variations of fatigue life are greatly influenced by the temperature and this tendency is more remarkable in the welded material.

Extremely Low Cycle Fatigue Behavior of Additively 1. AM 17-4PH stainless steel had a lower fatigue life when compared to wrought 17-4PH stainless steel when subjected to large inelastic cyclic strains. Voids and defects within the AM steel due to unmelted particles contributed to the reduction in fatigue life. 2. AM 17-4PH stainless steel exhibits higher post-yield strain hardening that wrought
