Effect of Boron Addition on Creep Strain during Impression Creep of P91 Steel

, 2019
In an attempt to understand the effect of boron addition on creep deformation behavior under high stress and high temperature in martensitic P91 steel, impression creep tests were carried out on boron-free P91 (P91) and boron-added P91 (P91B) steels. The

The development of advanced creep constitutive equations for high chromium alloy steel (P91) at transition stress range

Creep damage is a time-dependent deformation in metals under a constant stress at high temperature condition. Since the 1980s, high chromium alloy steel P91 (9%Cr-1%Mo-0.25%V) is highly demanded in high temperature industries (Saha, 2003).

Determination of energy dissipation and process instability in various alloys on the basis of plastometric tests

Metalurgija, 2013
Energy dissipation and areas of process instability were investigated in two alloys. The first one was brass, the second one was the steel 9 Cr (P91). The tests were performed on torsion plastometer Setaram and on compression plastometer Gleeble.
