“…However, for the high-strength materials, the increase in their fatigue limits is extremely difficult and the fatigue strengths may remain constant or even decrease with a further increase in the tensile strengths, while the detailed mechanisms are still mysterious. [9,10,20] In this investigation, NC Cu and Cu-Al alloys prepared by HPT were cyclically deformed to critically explore several questions. Do the fatigue strengths still increase with lowering of the SFE in NC Cu-Al with higher strength obtained by HPT?…”

“…For treated specimens with defects less than 100µm, loaded in tension, crack initiation occurred at subsurface inclusions (Fig.9). This type of fatigue failure surface is often observed in high strength steels [12,13] and is often associated with the Very High Cycle Fatigue domain(VHCF) for different types of material: aluminium alloys from the AlSi and AlMgSi families, copper and titanium alloys and also for the magnesium alloy AZ 91 [14,15,16,17].…”

“…It was assumed in the previous section that the relationship between the hardness and the fatigue strength is linear. However, experimental results taken from the literature [14,31,32] show that the fatigue strength increases linearly with increasing hardness, up until a certain value, after which the fatigue strength drops (see Figure 16). The objective in this section is to highlight the flexibility of the proposed approach by using a more complex expression for the crack propagation threshold, taken from the literature [31].…”

“…It has been shown in the literature [14,31,33,34] that the Murakami criterion is appropriate for modelling small defects where the propagation fatigue threshold increases with the crack size and hardness. For long cracks or for materials with high hardness the problem is different and the crack propagation threshold does not depend on the crack size and tends to decrease with the hardness.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. AbstractThis work investigates the effect of natural and artificial surface defects and quenching on the fatigue strength of a Boron Steel (22MnB5). A vast experimental campaign has been undertaken to study the high cycle fatigue behaviour and more specifically the fatigue damage mechanisms observed in quenched and untreated materials, under different loading conditions and with differents artificial defects sizes (from 25µm to 370 µm radius). In order to test the sheet metal in shear an original test apparatus is used. The critical defect size is determined to be 100±50µm. This critical size does not appear to depend on the loading type or the microstructure of the material (i.e. ferritic-perlitic or martensitic). However, for large defects, the quenched material is more sensitive to the defect size than the untreated material. For a defect size range of 100µm to 300µm the slope of the Kitagawa-Takahashi diagram is approximately -1/3 and -1/6 for the quenched and untreated materials respectively. A probabilistic approach that leads naturally to a probabilistic Kitagawa type diagram is developed. This methodology can be used to explain the relationship between the influence of the heat treatment and the defect size on the fatigue behaviour of this steel.

“…However, it is very time and money consuming to perform fatigue tests. Therefore, many attempts have been made to determine the fatigue strength in cost-effective way relating fatigue strength to other mechanical properties, such as yield strength, tensile strength, hardness (Pang et al, 2013;Murakami et al, 2002).…”

The fatigue failure is the reason of (90%) of mechanical failures. This work tries improving the fatigue strength and increasing the fatigue life for steel bars that used in concrete reinforcing. Tensile test were done to find the mechanical properties of steel bar. The heating over critical temperature (AC 3 ) and cooling by different cooling rates were done for steel bars, and tested this samples by tensile and fatigue tests. The tensile test results show increasing in yield and tensile strength for sample that cooled by oil (medium cooling rate).The fatigue test results show increasing in the fatigue life for samples that cooled by oil.
