Overview of mechanisms involved during the quenching and partitioning process in steels [PDF]

, 2011
The application of the quenching and partitioning (Q&P) process in steels involves a microstructural evolution that is more complex than just the formation of martensite followed by carbon partitioning from martensite to austenite.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Study on the Influence of Element Partitioning on the Cryogenic Toughness of Intercritical Quenched 9Ni Steel [PDF]

Archives of Metallurgy and Materials
To study the promotion mechanism of the quenching, intercritical quenching, and tempering process on the cryogenic toughness of 9Ni steel, the evolution characteristics of reversed austenite in the process were investigated.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Dilatometer analysis of the one step quenching and partitioning process in a 1.5%Si steel

, 2014
A one step quenching and partitioning process was applied to a 0.2%C-2.0%Mn-0.5%Cr- 1.5%Si steel by quenching austenitised samples to several different temperatures below the experimentally determined martensite start temperature of 397 °C and ...

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...
