Effects of annealing and quenching temperature on microstructure evolution and mechanical properties in Fe-0.17C-2.10Mn-0.51Si steel

Materials & Design
The optimum mechanical properties of Fe-0.17C-2.10Mn-0.51Si steel are achieved by adjusting annealing and quenching temperatures. Annealing at 790 °C for 300 s, followed by quenching at 310 °C for 15 s and partitioning at 460 °C for 50 s, results in a ...

Observation of an Isothermal Transformation during Quenching and Partitioning Processing

, 2009
The kinetics of the isothermal transformation, which occurs during a single-step quenching and partitioning (Q and P) process, was analyzed by means of dilatometry. Experiments revealed that an isothermal transformation with very specific characteristics

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Quenching and Partitioning of High-Aluminum Steels

, 2019
The quenching and partitioning response of aluminum-containing steels was investigated primarily through dilatometry and microstructural analysis through electron backscatter diffraction. It was found that 2-3 wt-% aluminum content raises the Ac3 temperature to levels that cannot be predicted by current thermodynamic models.
