Structure submicrocrystalline alloys Cu - Al [PDF]

, 2017
According to experimental data and the proposed models for all modes of severe plastic deformation, fragmentation of the grain structure in metals and alloys is ensured by the development of shear plastic deformation without the formation of pores and ...

Strain weakening and superplasticity in a Bi-Sn eutectic alloy processed by high-pressure torsion

, 2014
High-pressure torsion (HPT) was conducted on disks of a Bi-Sn eutectic alloy under a pressure of 6.0 GPa. The microstructural evolution was studied by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Measurements of Vickers

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.

Complementary use of TEM and APT for the investigation of steels nanostructured by severe plastic deformation

, 2009
The properties of bulk nanostructured materials are often controlled by atomic scale features like segregation along defects or composition gradients.

Homemade yeast by using tropical fruits through fermentation process [PDF]

, 2020
Yeast is one type of bacteria that is used in baking industry and as the crucial parameters to determine the softness of the bread. Many tropical fruits can be used as a medium to produce yeast. The main goal of this study is to produce homemade yeast by

Twin-induced plasticity of an ECAP-processed TWIP steel [PDF]

, 2017
The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult.

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.

Early Stages of Plastic Deformation in Low and High SFE Pure Metals

Metals, 2020
Severe plastic deformation (SPD) techniques are known to promote exceptional mechanical properties due to their ability to induce significant grain and cell size refinement. Cell and grain refinement are driven by continuous newly introduced dislocations

Effect of cathodic hydrogen charging on the surface of duplex stainless steel [PDF]

, 1993
The effect of cathodic hydrogen charging on the mechanical properties of steels has been extensively investigated (1-5). There is a general agreement, that cathodic harging during a tensile test leads to reduction in ductility, and embrittlement (5-7 ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.
