Microstress partitioning in porous and microcracked synthetic cordierite

As a continuation of earlier work on thermal expansion in extruded porous cordierite honeycombs, high-temperature neutron diffraction allowed us to observe lattice strains as a function of temperature. The transfer of grain microstrain (and stress) between the main (orthorhombic) cordierite phase and the minority spinel phase could be experimentally captured and rationalized by simple stress balance equations.
