A New Technique

Creep deformation localization is a common occurrence generally found in high temperature components, typically at weldments and geometrical discontinuities. The deformation in a small region cannot be measured by a conventional displacement gage. A new technique for measuring long-term local creep deformation was developed. It uses quartz optical fiber marking, remote monitoring, and image processing. Long-term measurements of the creep deformations of base metal, weld metal, and heat-affected zone in cross-weld specimens were performed at high temperature, which verify the new technique. Strain distributions and evolutions in the weldments are obtained.

A new technique is described which allows the quantitative exchange of copper(II) into ZSM-5 zeolites. The sequence consists of two steps: (i) impregnation of the zeolite with copper(II) in amounts higher than the exchange capacity; (ii) leaching of the copper in excess with respect to the exchange capacity with a chlorobenzene-water mixture at high temperature. The performances of the new materials in the hydrolysis of chlorobenzene, as well as preliminary informations on the nature of the catalyst and the type of mechanism are presented.
