Laves-phase evolution during aging in fine grained heat-affected zone of a tungsten-strengthened 9% Cr steel weldment [PDF]
, 2015 The precipitation and coarsening of Laves-phase in the fine grained heat-affected zone (FGHAZ) of a 9% Cr steel P92 welded joint during thermal aging at 923 K were investigated and compared to the base metal (BM), in order to clarify their effects on the

Journal of Materials Research and Technology, 2020 The alternation of creep properties is unavoidable in welded structures after suffering from cyclic damage, which may lead to the premature failure of power plant units and hard to predict. This work is devoted to clarify the influence of prior low cycle

Nuclear Materials and Energy, 2017 At the inner baffle of the AUG divertor massive polished inserts of tungsten and P92 steel were installed to measure the erosion by arcing. For tungsten most of the traces are less than 0.4µm deep and a similar amount of tungsten is deposited close to ...

Design of a new 11Cr martensitic steel and evaluation of its long-term creep rupture strengths
Journal of Materials Research and Technology, 2022 A new grade of 11 wt% Cr steel was designed in which no nitrogen was added to minimise the driving force of the Z-phase formation and hence to maximise the stability of the fine MX precipitate particles. But, 6 wt% Co was added to completely suppress the

Research Situation of Welding Performance for P92 Heat Resistant Steel
Journal of Physics: Conference Series, 2021 Abstract In this paper, the welding performance of P92 ferritic heat resistant steel in recent years was introduced. P92 steel was a ferritic/martensitic steel, which had been brought to commercial maturity during the last decade due to its excellent high temperature performances.

Arc erosion of full metal plasma facing components at the inner baffle region of ASDEX Upgrade
Nuclear Materials and Energy, 2016 At the inner baffle of the AUG divertor massive polished inserts of tungsten and P92 steel were installed to measure the erosion by arcing. For tungsten most of the traces are less than 0.4µm deep and a similar amount of tungsten is deposited close to ...

Origin of Threshold Stresses in a P92-type Steel
Transactions of the Indian Institute of Metals, 2015 The creep behavior of a P92-type steel was examined at 923 K. The threshold shear stress of 51 MPa was revealed by an analysis of steady state creep behavior at applied stress ranging from 118 to 200 MPa. The tempered martensite lath structure stabilized by M23C6-type carbide particles with an average size of about 110 nm and MX-type carbonitrides with
