Microstructural and Texture Evolution of Pearlite-Drawn Wires for Flexible Marine Pipelines: Investigating the Effect of Heat Treatments on Mechanical Properties

Metals, 2023
Flexible pipelines connect offshore platforms to subsea production systems due to their high flexibility, applicability, and recycling. Flexible armor layers in flexible pipelines are constructed using the parallel helical wrapping of several rectangular

Rejuvenation behaviors of recovery-annealed Cu–Zr metallic glass with different thermal treatment conditions: a molecular dynamics study

Journal of Materials Research and Technology, 2022
The recovery annealing process, which reheats the relaxed metallic glass (MG) to a certain temperature above glass transition temperature and subsequently rapid quenched, could tailor the sample to a less relaxed state, called as rejuvenation process ...

The Post-forging Heat Treatment Process of 9Cr Martensitic Heat-resistant Steel [PDF]

Teshugang
9Cr martensitic heat-resistant steel is an important candidate material for ultra-supercritical steam turbine rotors. Due to the large size of the rotor forgings， there is a greater tendency for microstructure inheritance.
