摘要
Following a preceding work on cordicrite thermal expansion, high temperature neutron diffraction has allowed observation of lattice strain with temperature in extruded porous cordierite in the form of a rod. The temperature dependence of the grain micro-stress in the rod was determined from neutron diffraction data (by comparison with powder data) and from the macroscopic thermal expansion (by the integrity factor model). The two methods are in good agreement. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
