Review: Modes and Processes of Severe Plastic Deformation (SPD) [PDF]

Materials, 2018
In this review, severe plastic deformation (SPD) is considered as a materials processing technology. The deformation mode is the principal characteristic differentiating SPD techniques from common forming operations. For large plastic strains, deformation mode depends on the distribution of strain rates between continuum slip lines and can be varied ...

Severe plastic deformation (SPD) of biodegradable magnesium alloys and composites: A review of developments and prospects

Journal of Magnesium and Alloys, 2022
The use of magnesium in orthopedic and cardiovascular applications has been widely attracted by diminishing the risk of abnormal interaction of the implant with the body tissue and eliminating the second surgery to remove it from the body.

Advanced Photocatalysts for CO₂ Conversion by Severe Plastic Deformation (SPD). [PDF]

Materials (Basel), 2023
Excessive CO2 emission from fossil fuel usage has resulted in global warming and environmental crises. To solve this problem, the photocatalytic conversion of CO2 to CO or useful components is a new strategy that has received significant attention. The main challenge in this regard is exploring photocatalysts with high efficiency for CO2 photoreduction.

The Cyclic Deformation Behavior of Severe Plastic Deformation (SPD) Metals and the Influential Factors [PDF]

Metals, 2012
A deeper understanding of the mechanical behavior of ultra-fine (UF) and nanocrystalline (NC) grained metals is necessary with the growing interest in using UF and NC grained metals for structural applications.

Inhibition of metal dusting corrosion on Fe-based alloy by combined near surface severe plastic deformation (NS-SPD) and thermochemical treatment

Corrosion Science, 2021
Abstract Combined NS-SPD and thermochemical treatment has been used to improve the metal dusting corrosion resistance of Incoloy 800. After testing under infinite carbon activity for 20−100 h, carbon was not found in the NS-SPD region while corrosion products formed in the non-NS-SPD region.

Processing of metals by severe plastic deformation (SPD) – structure and mechanical properties respond [PDF]

Metalurgija, 2008
SPD methods are used to convert coarse grain metals and alloys into ultrafine grained (UFG) materials. Obtained UFG materials then possess improved mechanical and physical properties which destine them for a wide commercial use.

Conceptual Analysis on Severe Plastic Deformation Processes of Shape Memory Alloys: Mechanical Properties and Microstructure Characterization

Metals, 2023
Shape memory alloys (SMAs) are types of materials that can restore their original shape upon severe or quasi-plastic deformation, being exposed to specific external stimuli, including heating, electric current, magnetic field, etc. They are a category of
