Quenching and partitioning process in ductile cast irons

, 2014
A commercial ductile iron alloy was submitted to quenching and partitioning (Q&S) process. Samples were austenitized at 900° C for two hours, quenched at 170°C and held at this temperature for 2 minutes and finally were re-heated in temperature between

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.

Enhancing strength and ductility in ultrahigh-strength steel via flash-heated IQP with lamellar heterostructure and chemical heterogeneity

Materials & Design
To develop ultrahigh-strength steel with both excellent mechanical properties and cost efficiency, this study integrates complete austenitization (CA), intercritical quenching (IQ), and flash heating quenching and partitioning (FHP).

Quenching and Partitioning (Q&P) technology

Book of abstracts of the 17th International symposium of the Croatian Metallurgical Society - SHMD 2024, Materials and metallurgy
The direction of finishing heat treatment, which is based on the principle of Quenching and Partitioning (Q&P), has been actively developing in recent years. Q&P technology (it can be considered a type of isothermal hardening) can be applied to a wide range of steels, including those with a wider range of carbon concentrations.
