Here we present a design for a magnetic avalanche digital detector (MADD) based on a ferromagnetic ring geometry. The sensor has several advantages over previous designs [Megens, M., et al., 2005]. Firstly it operates in an entirely digital manner, rather than relying on reversible deformations within a ferromagnetic element as has been proposed for use in other single bead sensors [Miller, M., et...
The microstructure of a quartzite experimentally deformed and partially recrystallised at 900 o C, 1.2 GPa confining pressure and strain rate 10 -6 /s was investigated using orientation contrast and electron backscatter diffraction (EBSD). Boundaries between misoriented domains (grains or subgrains) were determined by image analysis of orientation contrast images. In each domain,...
An expression for the stress of martensite in dual-phase steel was developed, which shows the interdependence of the stress of martensite and strain hardening in the ferrite matrix and the contribution of microstructural variables (the volume fraction of martensite f m , ferrite grain size d f , and martensite particle size d m . The onset of plastic deformation of martensite...
