Electron Microscopic Study of Structural Changes in 18-8 Austenite Stainless Steel after Solution and Precipitation Treatment

In order to investigate lattice defects of 18-8 stainless steel after solution, precipitation and resolution treatments, thin films prepared from bulk specimens after the heat treatments were examined by means of transmission electron microscopy. In addition, measurements of the internal friction, specific gravity and electrical resistivity as well as Huey corrosion tests were conducted. The ex...

Dynamic Recrystallization under Hot Deformation of a PH Stainless Steel

Dynamic recrystallization, DRX, behaviour of a precipitation hardened, PH, stainless steel was studied in connection with microstructural developments in a compression test. The experimental results showed that the dominant mechanism of softening is DRX, but at high strain rates and low temperatures, ie, high Zener-Holman parameter, Z, work hardening and dynamic recovery, DRV, produced a pancke...

Crystallography of Widmanstätten austenite in duplex stainless steel weld metal

Two kinds of austenite grow from d-ferrite during the cooling of the duplex stainless steel weld deposits studied here, Widmanstätten plates and allotriomorphs which precipitate at d–d grain boundaries. It is found using microtexture measurements that the preferred crystallographic orientation of the Widmanstätten austenite can be estimated using established theory if it is assumed that there i...
