Journal ArticleDOI
A novel ultra-high strength maraging steel with balanced ductility and creep resistance achieved by nanoscale β-NiAl and Laves phase precipitates
L. Sun,T.H. Simm,Tomas L. Martin,S. McAdam,D.R. Galvin,Karen Perkins,Paul A. J. Bagot,Michael P. Moody,S. W. Ooi,P. Hill,M. Rawson,H.K.D.H. Bhadeshia +11 more
TL;DR: In this paper, a novel ultra-high strength precipitation hardened martensitic steel with balanced ductility and creep resistance has been developed using a unique combination of nanometre scale intermetallic precipitates of Laves phases and β-NiAl to achieve such properties.
Journal ArticleDOI
The dislocation behaviour and GND development in a nickel based superalloy during creep
TL;DR: In this article, the authors investigated the storage of geometrically necessary (GND) and statistically stored (SSD) dislocations in a nickel-based superalloy.
Journal ArticleDOI
In situ observation of strain and phase transformation in plastically deformed 301 austenitic stainless steel
Yadunandan Das,A. N. Forsey,T.H. Simm,Karen Perkins,Michael E. Fitzpatrick,S. Gungor,Richard J. Moat +6 more
TL;DR: In this article, a strain-induced martensitic transformation is studied by in situ digital image correlation (DIC) in a scanning electron microscope, which enables mapping of transformation strains with high confidence.
Journal ArticleDOI
Peak Broadening Anisotropy and the Contrast Factor in Metal Alloys
TL;DR: In this paper, the authors use several practical examples of the use of DPPA to highlight the issues of broadening anisotropy in hexagonal close packed (HCP) alloys.
Journal ArticleDOI
A SANS and APT study of precipitate evolution and strengthening in a maraging steel
T.H. Simm,L. Sun,D.R. Galvin,Elliot P. Gilbert,D. Alba Venero,Y. Li,Tomas L. Martin,Paul A. J. Bagot,Michael P. Moody,P. Hill,Harry Bhadeshia,Soran Birosca,M. Rawson,Karen Perkins +13 more
TL;DR: In this article, a combination of the characterisation techniques small angle neutron scattering (SANS) and atom probe tomography (APT) are used to study the precipitation in a maraging steel.
