Small angle neutron scattering (SANS) procedure to analyse the residual porosity

Small-angle neutron scattering (SANS) was used in a rather original way for microporosity characterization in functionally graded and laminated Al2O3/Y-ZrO2 ceramics. The porosity characteristics (volume fraction, size distribution, specific surface) of these materials were obtained by SANS with a high degree of accuracy. This non-destructive technique yields information on the total volume fraction of residual pores (both open and closed). The SANS experiments bring novel and valuable information on influence of the HIP process on porosity and the relation between the detected internal stresses and porosity.
