Attaining High Functional Performance in Biodegradable Mg-Alloys: An Overview of Challenges and Prospects for the Mg-Zn-Ca System
Vinogradov, Alexei; Merson, Evgeniy; Myagkikh, Pavel; Linderov, Mikhail; Brilevsky, Alexandr; Merson, Dmitry (Peer reviewed; Journal article, 2023)This article presents a concise overview of modern achievements and existing knowledge gaps in the area of biodegradable magnesium alloys. Hundreds of Mg-based alloys have been proposed as candidates for temporary implants, ... -
Effect of Air Storage on Stress Corrosion Cracking of ZK60 Alloy Induced by Preliminary Immersion in NaCl-Based Corrosion Solution
Merson, Evgeniy; Poluyanov, Vitaliy; Myagkikh, Pavel; Merson, Dmitri; Vinogradov, Alexei (Peer reviewed; Journal article, 2022)The preliminary exposure of Mg alloys to corrosion solutions can cause their embrittlement. The phenomenon is referred to as pre-exposure stress corrosion cracking (PESCC). It has been reported that relatively long storage ... -
Effect of Hydrogen Concentration and Strain Rate on Hydrogen Embrittlement of Ultra-Fine-Grained Low-Carbon Steel
Merson, Evgeniy; Myagkikh, Pavel; Klevtsov, G.V.; Merson, Dmitri; Vinogradov, Alexey (Chapter, 2021)During the last few decades, keen attention has been paid to the advanced steels with the ultra-fine-grained (UFG) microstructure manufactured by severe plastic deformation (SPD) techniques. Although these materials often ... -
Fractographic features of technically pure magnesium, AZ31 and ZK60 alloys subjected to stress corrosion cracking
Merson, Evgeniy; Poluyanov, Vitaliy; Myagkikh, Pavel; Merson, Dmitri; Vinogradov, Alexey (Peer reviewed; Journal article, 2020)Using quantitative fractography, the present study clarifies the effect of chemical composition and preliminary plastic deformation on the fracture mode of structural magnesium alloys experienced stress corrosion cracking ... -
The fundamental difference between cleavage and hydrogen-assisted quasi-cleavage in ferritic materials revealed by multiscale quantitative fractographic and side surface characterization
Merson, Evgeniy; Myagkikh, Pavel; Poluyanov, Vitaliy; Dorogov, Maxim; Merson, Dmitry; Vinogradov, Alexey (Peer reviewed; Journal article, 2021)The fracture surfaces and cracks in technically pure iron, Fe-2.5% Si alloy and low-carbon steel grade S235JR produced by quasi-cleavage (QC) hydrogen-assisted cracking (HAC) as well as by true cleavage (TC) were studied ... -
Inhibiting stress corrosion cracking by removing corrosion products from the Mg-Zn-Zr alloy pre-exposed to corrosion solutions
Merson, Evgeniy; Poluyanov, Vitaliy; Myagkikh, Pavel; Merson, Dmitry; Vinogradov, Alexey (Peer reviewed; Journal article, 2021)Magnesium and its alloys are susceptible to stress-corrosion cracking (SCC), which can manifest itself during the slow-strain rate tensile (SSRT) testing in air if the specimens were pre-exposed to corrosive media. This ... -
On the role of pre-exposure time and corrosion products in stress-corrosion cracking of ZK60 and AZ31 magnesium alloys
Merson, Evgeniy; Poluyanov, Vitaliy; Myagkikh, Pavel; Merson, Dmitry; Vinogradov, Alexey (Peer reviewed; Journal article, 2021)Pre-exposure of Mg alloys to corrosive media causes their embrittlement, which has been long associated with diffusible hydrogen penetrating into the metal. The time of the pre-exposure was suggested to promote embrittlement ...
