The obtained results show that introducing even small amounts of aluminium into Cu-Sn10 alloy causes grain size reduction.
The results show, that due to grain size reduction, the alloy tensile strength increases.
The concentrations of a, b, c,... , x came from chemical analysis of the given alloy, while densities of the elements were taken from the literature data.

This is realised by a Personal Computer which is equipped with
a data acquisition unit.
Summarised, the intended forming process offers the following advantages: • Reduction of forming steps for complex work piece geometries, • reduction and respectively prevention of burr, • fabrication of complex thin-walled form parts, • fabrication of massive forming parts out of material with restricted forming ability, • selective strengthening by local strain hardening as well as • substitution of heat treatment by strain hardening.

The results confirmed the presence of sphalerite (ZnS), which is formed in the reduction environment during pyrolysis.
In comparison with data in literature, the achieved Al recovery from solid pyrolytic product is considerably lower, in our case only approximately 20 % (after subtraction of the ash content in grains of pyrolytic carbon).

Notice that the electronic states associated with dangling bond
defects have energy lying within the band gap and it leads to a reduction in the band gap of the SiCNWs.
It is worth mentioning that we have found no experimental data in the literature for the width, orientation and cross-section considered in this work.
Indeed, the reduction of the SiC-NWs diameter to the molecular scale is essential to the better understanding of their true one-dimensional behavior.

This reduction of total stack power over time is predominantly due to the voltage loss of two cells in the stack.
Advantages of such cells, in comparison with electrolyte- and anode-supported cells, are improved robustness and thermal performance along with a significant reduction in materials costs.

Comparison of obtained
CTEs in Fig. 3 shows that the expansion in L direction is substantially lower and in T direction
higher than that of reference Cu confirming thus the role of C fibres in the reduction of thermal
expansion of the Cu-K1100 composite.
The inspection of the thermal expansion data reveals some distinctive characteristics including two distinct knees appearing both in heating and cooling branches of relative elongations.
Rudajevova et al. [9] showed that the permanent reduction in the specimen length was observed in composite pre-deformed in tension, whereas permanent elongation was recorded in composite predeformed in compression.

These data are also processed to calculate or identify input parameters for the numerical investigations.
By simple uniaxial compression tests, measurement of axial and radial stresses and by numerical identification of input parameters the necessary data for Drucker-Prager-Cap material model in ABAQUS can be gained.
Fig. 4: Compressibility in layer compression test for disks compressed with different compression stresses made of chips Having a closer look on the tested specimens it can be seen that the reduction in height for the disks compressed with lower stresses in the chips pressing process is higher than for those being produced with 200 N/mm² or 300 N/mm², respectively.
An experimental setup for chip pressing that allows compressing the chips with different loads as to record important process data during the experiments was presented.
