Although these studies offer promising results, comprehensively investigating the fractures that form during multi-pass ECAP is necessary to maximise ECAP workability, improve ECAP efficiency, and understand the damage mechanism of ECAP-processed materials. 6061 Al is an aluminium alloy that has been extensively used in ECAP processing to realise ultrafine grain sizes (e.g. [7]) and improve mechanical properties (e.g. [8]).
After ECAP, the tensile properties and the cross-section hardness of the ECAP bars were tested.
The damage factors were large and concentrated at the upper and lower parts of the samples(Fig. 3).
The maximum damage factors were almost inversely proportional to the applied back-pressure (Fig. 4).

Our efforts are directed to the noise properties assessment.
In addition the noise analysis is affected by the internal polarization phenomena and the material residual humidity.

In order to optimize and increase the reliability of the experiment, the pressing pressure (P), holding pressure time (t) and the die tooling temperature (T) were taken as quantitative factors.
The effect of applied pressure on the mechanical properties of the base material and the cladding layer was determined on a longitudinal section of the obtained samples by the Vickers method (GOST 2999-75).
The presence of a brittle intermetallic layer with low plastic properties (σb=15÷17MPa) explains the low strength properties of the obtained compound.

Zirconia-based ceramics exhibit excellent mechanical properties and biocompatibility in dental applications.
Current technologies have successfully produced crown teeth with outstanding mechanical properties.
While zirconia has excellent mechanical properties and biocompatibility for crown teeth application, crown teeth with properties nearly identical to those of real human teeth have yet to be realized.
The translucency of zirconia can be influenced by many factors, such as microstructural homogeneity, density, powder size, and sintering temperature.
To achieve optimum translucency and mechanical properties, the recommended sintering temperature is 1200 °C.
