Corrosion testing, conducted in simulated bodily fluid at bodily pH levels to mimic conditions in the human body, revealed consistent corrosion rates across several techniques (mass loss, hydrogen evolution, and electrochemical impedance spectroscopy (EIS)), showing that severe plastic deformation deteriorates corrosion resistance for this material.sp.info Effects of severe plastic deformation on the The difference is attributed to the characteristics of severe plastic deformation (SPD) structures obtained by ECAP. Mechanical machining resulted in a further severe microstructure refinement of the SPD surface layer with nano-grains/subgrains, which is accompanied with a dramatic increase of both the hardness and the elastic modulus of the sp.info Effect of Severe Plastic Deformation on the Mechanical Feb 12, 2020 · In chips, grains were elongated in one direction due to severe plastic flow. Hardness and ultimate tensile strength increased with thickness reduction. Chip hardness is 60% more than as-received material due to microstructure refinement.sp.info The effects of severe plastic deformation on the Oct 01, 2020 · Severe plastic deformation (SPD) produces ultra-high strength in Mg-ZKQX6000. • SPD causes precipitate-induced embrittlement derived from a high alloying content. • Corrosion rates are high in simulated bodily fluid held at physiological pH levels. • Corrosion rates are consistent across multiple types of testing. •

In this study, two innovative surface severe plastic deformation (SSPD) methods, namely abrasive waterjet peening (AWJP) and ultrasonic nanocrystal surface modification (UNSM), were applied to a 304 stainless steel to improve the mechanical behavior.sp.info Effects of Surface Severe Plastic Deformation on the In this study, two innovative surface severe plastic deformation (SSPD) methods, namely abrasive waterjet peening (AWJP) and ultrasonic nanocrystal surface modification (UNSM), were applied to a 304 stainless steel to improve the mechanical behavior. The surface roughness, microstructure, residual stress, hardness, and tensile mechanical properties of the alloy after sp.info Effects of the Severe Plastic Deformation on the Magnetic Nov 17, 2021 · Razumov et al. state that during severe plastic deformation (SPD) the mechanical energy delivered to the alloy partially converts to the internal energy of the alloy. This energy dissipation process is influenced by the temperature and deformation conditions, and it can be realized by the dislocation glide and climb, dynamic recrystallization, amorphization, and sp.info The Effect of Severe Plastic Deformation on the Structure The structural-phase state and mechanical properties of commercial aluminum alloys produced by severe plastic deformation are studied and compared to the initial polycrystalline state. This kind of treatment is found to give rise to the formation of a homogeneous ultrafine-grained structure with second-phase particles occurring predominantly along grain boundaries.

Mar 19, 2014 · Abstract. The present work investigates the microstructural and mechanical properties of commercial purity titanium after processing by a two-step severe plastic deformation procedure entailing warm equal channel angular pressing (ECAP) followed by cold rolling at liquid nitrogen temperature (LNT). The effect of subsequent cold rolling at room sp.info Effects of severe plastic deformation on the structure Jun 18, 2010 · Severe plastic deformation induced by high-pressure torsion (HPT) causes significant changes in the microstructure and thermo-mechanical properties of Zr 55 Cu 30 Al 10 Ni 5 bulk metallic glass. Although HPT does not directly lead to clear crystallization of the amorphous alloy, transmission electron microscopy reveals changes in the medium-range order.sp.info
