This method was demonstrated in several material
systems using zinc (Zn), aluminum (Al), and magnesium (Mg) alloys and nanoparticles of
aluminum oxide (Al2O3), silicon carbide (SiC), and titanium oxide (TiO2).
Recent works [5] on the Al-Ti-B master alloy grain refining system have used the free growth model to predict inoculant potency.
As seen in Table 1, the Al/SiC system has a 7.6% disregistry suggesting SiC is a potent nucleating agent for Al.

More information about DOE and its application can be found in Berger et al. [8].
Gunst et al. [9] highlight the fundamental concept, design strategies, and statistical properties of fractional factorial design.
The usage of OED is known in material modeling, where Valadimirov el al. [14] and Bambach et al [15] presented the identification of material models and parameters in plasticity models.
Additionally, Wiebenga el at. [17] used sequential robust optimization to identify optimal process parameters for V-bending process.
The first one is a thin plate spline (TPS) regresseion model as presented by Grzhibovskis et al [20].

Kumar et al. [8] examined Cattaneo-Christov flow, while Kumar et al. [9] provided a study for a Casson fluid.
Hybrid ferrofluid as nanoparticles are used by Tlili et al. [12] and Kumar et al. [13].
A non‐Fourier heat flux model for magnetohydrodynamic micropolar is presented by Kumar et al. [17] and for different physical aspects by Kumar et al. [18-20].
In the area of high temperature differences, Abd-El Aziz [30] studied the above effects on a moving semi-infinite plate with a mixed convection flow of a micropolar fluid.
Others performed the biosurfactants to act both as reducing agents and stabilizers in the synthesis of nanoparticles has been reported by Priyadarshini et al. [32], Kasture et al. [33] and Kumar et al. [34].

All the Al-doped 4H-SiC layers have been experimentally assessed by different technics.
Ohmic electrical contacts (Ti/Al/Ni) have been deposited in the corners of the samples.
Considering that during CVD process the Al atoms incorporated in situ are on substitutional sites, the measured SIMS Al densities correspond to the acceptor densities NA (NA = [Al]).
Fig. 3: Abacus correlating shift in Al0 line vs the Al concentration evaluated by SIMS [7].

A more systematic investigation started with the
work of Zhang and Farrar [1], rapidly followed by work of Kang et al. [2], Banguru et
al. [3] and finally the recent work by Keehan [4].
Banguru el al [3] presented their strength results in relation to the chemical composition of the weld metals by rationalising the chemical composition into a single parameter, Pcm.
In the work of Banguru et al. [3] a similar trend can be seen.
Both Zhang and Farrar and Kang et al.
Only Kang et al increased the nickel content further, to 7%.

Song et al.2) pointed out that 316L has better properties after solution annealing.
According to Silva et al.3) is this strain – induced α’ martensite transformation inhibited by adding the alloying element nitrogen N. 316LN has a mechanical stable microstructure.
Farahat and El-Bitar4) showed that the induced martensitic transformation starts for Ti- and Nb-alloyed austenitic steels between 36 % and 45 % of thickness reduction by cold rolling.
