Both uses an X-ray source in which penetrate the material and will described the material characteristics, so it can be used to reveal defects or incompatibility between materials in the object.
CT provides exact location, dimension, position among other material as well as material specification, such as linear attenuation coefficient and density.
Eq. (2) depicts how the X-ray interacts with the material within the object so that such material and its position can be guessed relatively among other materials within the object [11].
Following Eq. (3), a prediction on the material characteristic may be performed.

Introduction Zirconium and its alloys are extensively used as structural materials in nuclear reactors because of their unique combination of good corrosion resistance in water near 300oC, good mechanical properties and low neutron capture cross section for thermal neutrons [1-2].
It could be shown that nature and extent of irradiation is different in both materials. 100nm a 0.1mm 100nm b 0.1mm 100nm c 0.3mm Fig. 6.
It could be shown that nature and extent of irradiation is different in both materials Zr-2.5 Nb alloy pressure tubes The irradiated samples obtained from the 13 locations showed the average width, length and aspect ratio of the a grains in the range of 0.17-0.27 µm, 1.7-2.3 µm and 7.1-8.5 respectively.

Besides the manufacturing processes and joining configurations, different materials and heat treatment conditions were used to manufacture these panels:  AA2024-T3;  AA6056-T6;  AA6056-T4 and post welding treatment (PWHT) to T6 condition.
And the NASGRO law for the material AA2024-T3 due to the fact that this is a more complete law and the parameters for this material are published.

Introduction Development of the mechanisms and machines structures increases the requirements imposed on the materials used and the quality of the treated surface.
By now, considerable theoretical knowledge has been accumulated in the field of mechanical processing of materials.
However, control of the entire batch of raw material and cutting tools is not always possible in shops conditions.
