Abstract: Carbide coarsening has been investigated in a 12 percent CrMoV steel. Studies in the gauge length (creep exposed) and in the head (stress free ageing) for both interrupted and ruptured creep ...

Abstract: With modern welding methods, satisfactory microstructures in 9%CrMoV (P91) steel can be obtained with a modest variation in hardness and prior austenite grain size. However, there is always a ...

Abstract: Strainburst is the most common type of rockburst in deep excavations, which sometime result in heavy losses. This research studies the feasibility of a conceptualized destressing method for strainburst control. In this ...
