The double-edge effect of second-phase particles on the recrystallization behaviour and associated mechanical properties of metallic materials

Roland Logé, Ke Huang

Most industrial alloys contain a matrix phase and dispersed second-phase particles. Several thermomechanical processing (TMP) steps are usually needed to produce a final product, during which recrystallization and its related phenomena may take place. Seco ...

Study on the mixed dynamic recrystallization mechanism during the globularization process of laser-welded TA15 Ti-alloy joint under hot tensile deformation

Ke Huang

In this article, the hot deformation mechanism of a laser-welded near a TA15 Ti-alloy joint was studied by hot tensile tests conducted at temperatures ranging from 800 degrees C to 900 degrees C with strain rates ranging from 1.0 x 10(-1) s(-1) to 1.0 x 10 ...

The flow stress evolution and grain refinement mechanisms during hot deformation of Al-Mg alloy

Roland Logé, Ke Huang

In this study, the hot deformation behavior of an Al-1% Mg alloy with very coarse initial grain size was investigated in terms of flow stress evolution and grain refinement mechanism. The large grain size was employed to study the traditional continuous dy ...

Simultaneous strength and ductility enhancement of wire-arc directed energy deposited Al-Cu alloy by interlayer laser shock peening

Ke Huang, Yandong Jing

Wire-arc directed energy deposition (wire-arc DED), recognized for its ability to produce large-scale parts, has gained considerable attention. However, a critical issue with this method is the high prevalence of internal porosity defects found in the manu ...

On the sluggish recrystallization of a cold-rolled Al–Mn–Fe–Si alloy

Roland Logé, Ke Huang

Annealing of supersaturated AA3xxx alloys at low temperatures usually results in sluggish recrystallization kinetics. This is due to the joint effect of the following factors: low nucleation rate, reduced grain boundary mobility, and large amount of fine p ...

A critical assessment of experimental investigation of dynamic recrystallization of metallic materials

Roland Logé, Ke Huang

Dynamic recrystallization (DRX) often takes place during hot deformation of metallic materials, which then exerts significant influence on the final microstructures and mechanical properties of the formed components. A considerable number of published pape ...

Effect of heterogeneously distributed pre-existing dispersoids on the recrystallization behavior of a cold-rolled Al–Mn–Fe–Si alloy

Ke Huang

It is well known that strong concurrent precipitation, mainly located along grain/subgrain boundaries, results in a coarse and elongated grain structure, and unusual sharp P {011} and/or M {113} texture components during annealing of supersatur ...

Laser shock peening: A promising tool for tailoring metallic microstructures in selective laser melting

Manuel Ortega Varela De Seijas, Roland Logé, Ke Huang, Nikola Kalentics

Metallic parts made by Selective Laser Melting (SLM) are known for their heterogeneous microstructures in the as-built (AB) state. In this paper, Laser Shock Peening (ISP) was performed on a 316 L stainless steel part fabricated by SLM. The LSP treatment i ...

Azimuthal asymmetries of back-to-back pi(+/-) - (pi(0), eta, pi(+/-)) pairs in e(+) e(-) annihilation

Olivier Schneider, Sun Hee Kim, Mingkui Wang, Chao Wang, Ke Huang, Ho Ling Li, Yiming Li

This work reports the first observation of azimuthal asymmetries around the thrust axis in e(+)e(-) annihilation of pairs of back-to-back charged pions in one hemisphere, and pi(0) and eta mesons in the opposite hemisphere. These results are complemented b ...

Microstructure and flow stress evolution during hot deformation of 304L austenitic stainless steel in variable thermomechanical conditions

Roland Logé, Ke Huang

Most of industrial hot deformation processes are performed in variable conditions where the strain rate and/or deformation temperature are not constant. In this work, hot compression tests in both constant and varying strain rate conditions were performed ...

Controlling grain structure and texture in Al-Mn from the competition between precipitation and recrystallization

Roland Logé, Ke Huang

The recrystallization behaviour of Al-Mn alloys (AA3xxx series alloys) is affected by randomly distributed dispersoids present before annealing, by dispersoids precipitated at grain/subgrain boundaries before the onset of recrystallization, and by disperso ...
