The spatial variation in martensite tetragonality (c/a ratio) in Fe-0.77C (wt.%) alloy was investigated by means of pattern matching of electron backscatter diffraction patterns combined with high angular resolution electron backscatter diffraction analysis. It was found that the c/a ratio varies within a martensite block and between blocks. The c/a variation within a block is particularly evident in the vicinity of grain boundaries and shear strains are also present in addition to tetragonal… Expand


Real time observation of martensite transformation for a 0.4C low alloyed steel by neutron diffraction
Abstract A high-intensity and high-resolution neutron diffractometer with a thermomechanically controlled processing simulator was employed in-situ to investigate martensite transformation behaviorExpand
Determination of elastic strain fields and geometrically necessary dislocation distributions near nanoindents using electron back scatter diffraction
The deformation around a 500-nm deep Berkovich indent in a large grained Fe sample has been studied using high resolution electron back scatter diffraction (EBSD). EBSD patterns were obtained in aExpand
3D structural and atomic-scale analysis of lath martensite: Effect of the transformation sequence
Abstract To improve the fundamental understanding of the multi-scale characteristics of martensitic microstructures and their micro-mechanical properties, a multi-probe methodology is developed andExpand
Internal residual stress originated from Bain strain and its effect on hardness in Fe–Ni martensite
Abstract To further understand the internal residual stress that is microscopically generated via martensitic transformation in steels, the origin of internal strain attributed to Bain correspondenceExpand
High-resolution elastic strain measurement from electron backscatter diffraction patterns: new levels of sensitivity.
It is demonstrated that the shift between similar features in two electron backscatter diffraction patterns can be measured using cross-correlation based methods to +/- 0.05 pixels, which is an impressive and unique combination of high strain sensitivity, high spatial resolution and ease of use.

Atomic displacements due to C in Fe Ni C martensite
The ratio of the X-ray intensity in the 002 to that in the 200, 020 in martensite formed in fine-grained 18 pct Ni ∼ 1 pct C austenite provides a measure of the strength of the carbon displacementExpand
Microstructures and hardness of as-quenched martensites (0.10.5%C)
Four commercial steels with carbon contents in the range 0.1-0.5 wt.% have been examined in the as-quenched condition using electron microscopy, X-ray diffraction and atom probe tomography. TheExpand
Measurement of residual elastic strain and lattice rotations with high resolution electron backscatter diffraction.
High resolution electron backscatter diffraction has been used to analyse the residual elastic strain, lattice rotations and density of stored geometrically necessary dislocations in a sample of copper deformed to 10% total strain. Expand
Dislocation density within lath martensite in Fe-C and Fe-Ni alloys
Lath martensite structure has overwhelming industrial significance in most heat-treatable commercial steels. High dislocation density is one of major factors for high strength of lath martensite. ItExpand
Martensitic Transformation
The shape memory effect exhibited by Fe-Mn-Si based alloys is due to the γ(f.c.c.)-e(h.c.p.) martensitic transformation. The martensitic transformation induced by traction at room temperature in aExpand
