Creep Behaviour of P92 and P92 Welds at 675°C
Volume 6: Materials and Fabrication, Parts A and B, 2012The results of an accelerated creep test programme on the leading new build high temperature power plant pipework ferritic steel P92 and two P92 welds are presented. Tests were performed at 675°C, which is above the service operating temperature range recommended for P92, but allowed for more realistic operating stresses to be used ...

Creep Crack Growth of P92 Welds
Volume 6: Materials and Fabrication, Parts A and B, 2008This paper represents creep properties and creep crack growth properties for P92 welds. The CCG tests were carried out using cross-welded compact tension (C (T) specimens at several temperatures. The crack front was located at HAZ region to simulate Type IV crack.

P92 Implementation of physiotherapy led paediatric respiratory clinics
Monitoring and care delivery for children with respiratory disease, 2021Introduction The adult BTS bronchiectasis guidelines recommend patients have access to a physiotherapist to teach airway clearance, and that this is reviewed every 3 months (Hill et al 2019). While there are no guidelines for children, Chang et al(2018) reports that mild Bronchiectasis in children can be reversed if treated early enough.

Precipitate Phases in Normalized Ferritic/Martensitic Steel P92
Key Engineering Materials, 2018Precipitate phases in the P92 F/M steel after normalization at 1323 K (1050 °C) for 30 min followed by air cooling to room temperature have been investigated by transmission electron microscopy (TEM). Three types of phases consisting of M3C, MX and M2C have been identified.

Materials Characterization, 2020
Abstract The microstructural factors that contribute to hardening mechanisms were investigated to explain the effect of post-weld heat treatment (PWHT) on the hardness of P92 steel in IN740H/P92 dissimilar weld joints. This study presents experimental analysis of the distribution of microstructural factors such as precipitate size, precipitate ...
