The effect of severe plastic deformation on the Mg properties after CEC deformation

Journal of Magnesium and Alloys, 2020
In this study, the effect of severe plastic deformation on the Mg grain refinement and recovery mechanism was investigated. Technical pure magnesium was deformed at room temperature by cycling extrusion-compression (CEC) process up to large deformation ...

Ultrafine-grained low carbon steels by severe plastic deformation [PDF]

Metalurgija, 2008
The structure and properties of 0,14% C and 0,1% C - B low-carbon steels taken in two initial states, martensitic and ferritic-pearlitic, were studied after cold equal-channel angular (ECA) pressing.

Recrystallization in an Mg-Nd alloy processed by high-pressure torsion: a calorimetric analysis

Journal of Materials Research and Technology, 2020
Differential scanning calorimetry (DSC) was used to evaluate the recrystallization temperature and activation energy for an Mg-1.43Nd (wt.%) alloy after severe plastic deformation by high-pressure torsion (HPT) at room temperature up to 10 turns.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Production of Bulk Metallic Glasses by Severe Plastic Deformation

Metals, 2015
The aim of this study was to show the possibility to produce bulk metallic glass with severe plastic deformation. High pressure torsion was used to consolidate Zr-based metallic glass powder and deform it further to weld the powder particles together ...
