“…This concurs with a number of studies in the literature where short exposure to fatigue at a moderate stress amplitude is seen to result in a hardening effect. Mocko et al has shown this effect in a number of alloys including dual phase steels and medium carbon steels, where initial fatigue exposure causes an increase in yield strength in such materials [ 19 ]. This effect is apparent for fatigue exposures of 25% and 50% of the total fatigue life, however when increased to 75%, a significant decrease in residual flow stress is observed.…”

The mechanical behaviour of three ultra-high strength steels has been assessed; AerMet100, 300M and the recently developed corrosion resistant high strength steel, MLX-17. Material heat treatment profiles have been utilised to provide performance optimised for the aerospace industry and specimens have been tested to explore tensile and fatigue properties, in particular when combined with pre-strain to simulate the effects of overload. Testing of this kind has not been reported within the literature, particularly amongst ultra-high strength and corrosion-resistant steels. Baseline mechanical performance for all three materials in their heat-treated conditions has been established and properties such as yield strength and ultimate tensile strength have been assessed following a 75% and 95% pre-strain as well as fatigue in combination with a 75% and 95% pre-strain. Under all loading conditions, resultant tensile mechanical properties are not seen to witness a substantial degradation in performance, but an improvement in terms of yield strength and UTS, due to the role of work hardening. An alloy comparison has been carried out and responses are seen to vary slightly as a result of material microstructure. Correlation of pre-strain and pre-fatigue results with respect to baseline properties and microstructure has contributed to advancing the understanding of the mechanical behaviour of the aforementioned ultra-high strength steels.

“…The specimens were cut using electro-discharge machining (EDM). Tensile tests were carried out at quasi-static and dynamic loading regime using, respectively, with a servo-hydraulic testing machine and split Hopkinson tensile bar (Moćko et al, 2015(Moćko et al, , 2016. Simultaneously, plastic deformation was recorded and analysed using a digital image correlation software to determine strain distribution.…”

“…However, the author observed no significant change in the fracture behaviour for the base as well as the weld material. Mocho et al [172] investigated the deformation behaviour of DP500 steel at quasi-static and dynamic strain rates after initial fatigue loading and reported the localized strains for high strain rates to be higher than the quasi-static tests.

The behaviour of plain carbon as well as structural steels is qualitatively different at different regimes of strain rates and temperature when they are subjected to hot-working and impact-loading conditions. Ambient temperature and carbon content are the leading factors governing the deformation behaviour and substructural evolution of these steels. This review aims at investigating the mechanical behaviour of structural (or constructional) steels during their strain rate (ranging from very low to very high) as well as hot-working conditions and subsequently establishing the structure–property correlation. Rate-dependent constitutive equations play a significant role in predicting the material response, particularly where the experiments are difficult to perform. In this article, an extensive review is carried out on the merits and limitations of constitutive models which are commonly used to model the deformation behaviour of plain carbon steels.
