Creep crack growth behavior of P91 steel weldments

open access: yesThermal Science, 2019
The steels operating at elevated temperatures are well known to be exposed to premature failure due to cracking caused by constant thermal stress, i.e. secondary creep process. Therefore, creep crack growth (CCG) tests were carried out on compact tension (CT) specimens machined from P91 weld joint at 600°C to determine its behaviour in realistic ...

Measuring Dilution and Wear for Laser Cladding of Stellite 6 Produced on a P91 Steel Substrate using Two Different Heat Inputs

open access: yesMATEC Web of Conferences, 2016
Stellite 6 was deposited by laser cladding on a P91 substrate with energy inputs of 1 kW (P91-1) and 1.8 kW (P91–1.8). The chemical compositions, microstructures and surface roughnesses of these coatings were characterized by atomic absorption ...
