In another work using an aqueous magnetite ferrofluid, Gayatri et al. (2016) have observed particle clustering with abrupt change in the magnetic field strength at high nanoparticles concentration [18].
However, in another work, Santiago-Quinones et al. (2013) have proven that poor stability brings advantage to the magneto-viscosity.

Lee, et al [5] provided an interactive algorithm using both RSM and mathematical modelling to solve a parameter optimization problem in turning operation.
El-Axir [7] concentrates on response surface design methodology to model the effect of machining parameters on distribution of residual stresses for five different materials in turning operations.
Kaye, et al [8] used RSM in predicting tool flank wear using spindle speed change.

The microstructure of the single crystal Ni-based superalloys is composed of an ordered FCC A3B (γ’ phase) intermetallic phase (A = Ni, B = Al, Ti) dispersed in a disordered matrix that consists of FCC Ni-based solid solution strengthened by substitutional Co, Cr, Mo, W, Ta and Re alloying elements (γ phase) [2,3].
Previous work by Santos, et al [3] showed that low roughness, smooth titanium nitride layers with no cracking can be produced onto titanium substrates by laser gas nitriding through controlling laser and processing parameters.
The energy per line, El, is calculated as El = Pav/v, where Pav is the average power and v is the laser scanning speed.

This is in accordance with the tar result of iron ore catalytic pyrolysis study conducted by Zhao et.al. [6] whose mass of 9.89% at temperature of 500oC.
Kim et.al. [17] stated that the synthesis of phenolic resins was able to be facilitated by direct utilization of bio oil comprising high amount of phenol due to their higher reactivity, compared with other methoxylated or alkylated phenolic compounds.

Zheng et al. [8] uses further technique in shaping procedure of PM Mg-Ca via hot press (320 °C) followed by hot extrusion (300 °C).
However, Zulkoffli et al. [7] and Abdizadeh et al. [9] choses PM method in fabricating their product samples at sintering temperature of 500 °C and 575, 600, 625 °C respectively.
According to Bhuiyan et al. [11], grain size increases while the porosity decreases as sintering temperature increases.
Naceur et al. [13] which also agrees with the discovery reported that grain growth was observed with increasing sintering temperature.

Das et al. [14] established the radiation effects on flow past an impulsively started infinite vertical plate.
This result is in good agreement with the results of Raju et al. [18].
In their study Raju et al [28] concluded that velocity increases with an increase in the values of porosity parameter.

Thanks to these properties, Fe-Mn-Al austenitic steels have found application in automotive industry.
Zhang and Zhu have shown that with an increase in Al contents to 5% in Fe-25Mn-Al steel, anodic polarisation curves exhibit a stable passivation area in Na2SO4 solution, but in a more aggressive environment (3.5% NaCl), they occur in the active area. [9] Corrosion behaviour of Fe-C-Mn-Al steel has been confirmed by Altstetter et al. [1], researching substitutes for expensive Cr-Ni steels.
