Bauschinger effect in precipitation-strengthened aluminium alloy 2024

Materials Science and Engineering, 1987
Abstract The influence of precipitation strengthening on the Bauschinger effect of aluminium alloy 2024 has been investigated. The material was aged at 463 and 478 K for various lengths of time. Under certain aging and straining conditions, reverse flow curves with concave parts were observed.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Effect of non-isothermal retrogression and re-aging treatment on microstructure evolution and mechanical properties of Al–Zn–Mg–Cu alloy

Journal of Materials Research and Technology
The mechanical properties of rolled 7075 aluminum alloy treated by non-isothermal retrogression and re-aging can exceed the traditional peak aging (T6) and isothermal retrogression and re-aging. After non-isothermal retrogression and re-aging (NIA 180/60)

The effect of doubled CO2 and model basic state biases on the monsoon-ENSO system. I: Mean response and interannual variability [PDF]

, 2007
The impact of doubled CO2 concentration on the Asian summer monsoon is studied using a coupled ocean-atmosphere model. Both the mean seasonal precipitation and interannual monsoon variability are found to increase in the future climate scenario presented.

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

Unraveling the Effect of Tramp Elements on Phase Transformations in Steels by Combining CALPHAD Modeling and Experiments

Advanced Engineering Materials, EarlyView.
This study investigates how tramp elements from increased scrap usage influence phase transformations in low‐alloyed steel. Combining dilatometry and microscopy reveal that tramp elements delay transformations, reduce critical cooling rates and increase hardenability.
