【 摘 要 】

Centerless X ray diffractometers are specially designed for nondestructive residual stress measurements. The similarity between the X-ray diffraction based stress and texture measurement methods has led us to introduce measurement method for nondestructive (sample cutting-free) stress measuring devices, to describe the texture. After the determination of identical lattice plane series distribution with centerless and conventional diffractometers, advanced anisotropy measurements techniques were invented. The new examination methods were applied for a Late Roman silver artefact, the Perfume Box from the Seuso treasure. The spatial resolved qualitative assessment of the texture provided valuable insight on the processing of the material and manufacturing of the different parts of the artefact. The developed techniques are completely nondestructive, therefore the examined artefacts suffer no harm. The methods inherit the privileges of centerless diffractometers such as no object size limits.
