An optical pyrometer and a thermocouple were used measure and record
the time-temperature data of the front and the unattacked back surface of the specimens.
On examination of the data presented in Table 1, it is clear that the ZSS composite possesses the highest values of hardness (21.2 GPa), flexural strength (520 MPa) and fracture toughness (7.8 ± 0.6 MPa√m).
The data for ZrB2 is from Ref. 21.
This may be because of the marginal decrease in co-efficient of thermal expansion (CTE) of the matrix on addition of ZrC, and reduction in the mismatch between the constituent phases.
Reduction in the CTE is expected to improve the thermal shock resistance of the composites.

Generative AI tools are an intuitive solution for small datasets or data imbalance.
In our previous work [1], we used pix2pix [2] to augment data in order to address the issue of data imbalance. pix2pix is a deep learning framework based on a conditional GAN (Generative Adversarial Network [3]).
Quantum versions of machine learning models can leverage the unique properties of quantum bits (qubits) to require fewer training iterations and data points [6].
By utilizing N qubits, which can represent 2N -dimension data, the parameters required to train a Chinese character image generation model are significantly reduced.
That is, processing the data in the classical state.

The experimental data is compared with the kinetics predicted by the LE-NP and PE limits (dashed lines).
As a result, the cross-interface mobility was used as an adjustable parameter to fit the data.
In order to test the model further, the Mn mobility in austenite was used to model the experimental data at 755 and 775oC.
This expectation is in agreement with the experimental data over the temperature range from 725 to 775oC.
This was attributed to the build up of the substitutional element spike and the experimental data were successfully modeled

With the help of strain gauge equipment, experimental data were obtained on the forces acting on the rolls and the die of the CCRE-200 combined processing unit in the process of obtaining rods with a diameter of 5 and 9 mm.
The advantage of combined processing methods is the reduction in the number of metallurgical conversions and deformation stages.
The obtained data on electrical resistance are listed in Table 7.
From the presented data it can be seen that with an increase in the deformation rate, the electrical resistance also increases.

It was found that to improve the quality of the surface it is necessary to adjust the parameters of the powder processing of parts with high porosity in the direction of their reduction.
Following the suggestions of cutting insert manufacturer, the following finishing operation data were chosen: depth of cut (a) is 0.5 mm, feed (f) is 0.08 mm/rev. and 0.1 mm/rev. and cutting speed (v) is 130 m/min and 150 m/min.
The surface roughness measurements proved that the 3D surface roughness parameters describe the measured surface more accurately than 2D profile roughness parameters giving more reliable data about the surface.
