The effect of ferrite phases on the micromechanical response and crack initiation in the intercritical heat-affected zone of a welded 9Cr martensitic steel
(Wiley, 2018-02-08)This paper presents a crystal plasticity model to predict the tensile response and crack initiation in a mixed ferrite-martensite material with a low volume fraction of pro-eutectoid ferrite, representative of a welding-induced ... -
Microstructure modeling of high-temperature microcrack initiation and evolution in a welded 9Cr martensitic steel
(SAGE Publications, 2019-02-28)Welded joints in tempered 9Cr-1Mo operating at elevated temperatures are well known to be prone to premature failure due to cracking in the heat-affected zone. This paper describes a crystal plasticity model to predict the ... -
A physically-based creep damage model for effects of different precipitate types
(Elsevier, 2016-10-13)The development of a new precipitate coarsening continuum damage mechanics (CDM) model to simulate the multi-precipitate strengthening mechanisms present in 9Cr steels under high temperature creep deformation is presented ...
