Excerpts

The effect of sliding speed on the value of Ih is reduced at the low P and becomes almost insignificant at P = 1 MPa ( Table 3 ).

While a clear trend in the evolution of the interfacial strength and the rolling temperature was registered for the magnesium–aluminium interface, a less clear trend was registered for the other interface.

The content of α*-fiber shows an increasing trend, and {411}<148> and {100}<120> reach 14.6% and 6.88% as recrystallization was completed at 700°, respectively.

However, the tensile properties, particularly the E b showed an increasing trend with increasing the HAP concentration.

The high fitting degree shows that there is a highly significant linear correlation between σ p and ε ̈ c .

As the magnetic fields increase, the ΔS−T curve changes from the symmetrical herringbone to the asymmetric curve, indicating that the alloy phase transition type from the secondary phase transition to the primary phase transition and ΔS shows an increasing trend (because the primary phase transition is the change of material magnetic ordered state caused by lattice distortion, the resulting magnetic entropy change is much greater than the secondary phase transition and reaches values of 9.45 J/(kg·K) upon an applied field of 1.5 T). 4.

The maximum isothermal magnetic entropy change mutated after 20 min of heat treatment, and then showed an obvious trend of first increasing and then decreasing, and reached the maximum value after 2 h of heat treatment.

However, this paste showed the most rapid increase in BET surface area, as a significant difference was apparent even after the first 30 min and especially after one hour, i.e., between the initial and final setting time indicated by the Vicat needle (see Table 2 ), as well as between 60 and 120 min.

Since typical conversion of CO 2 to carbonate is very slow and inefficient under the conditions of ambient temperature and pressure, there has recently been an increasing trend in research on maximizing the mineral carbonation reaction using supercritical CO 2 .

Its effect on surface temperature is quite significant during the day but at night, due to low heat capacity of the plaster layer, the stored heat is quickly lost and the temperature rises only slightly.

From the experimental results obtained, the following conclusions can be drawn: The fresh properties of the developed mixes showed a decreasing trend with the increases in silica fume and RCA and with the inclusion of steel fibres.

According to Figure 9 a the OP-TMF life of the reference material, Esshete 1250, does not show a clear trend when the material is aged before OP-TMF testing.

In addition, OC (3rd column in Table 4 ) shows a clear trend, as it increases when the amount of SFG increases.

It can be seen that both curves have an increasing trend, which correlated with the increase in nano-reinforcement content.

In the case of k 2 and h coefficient values, there was an increasing trend of these parameters in the following series: La(III) > Pr(III) > Nd(III) > Ce(III).

Upon adding both reinforcements to Al matrix to form a hybrid nanocomposite, an interesting trend was observed.

It can be seen that with temperature increasing from RT to 550 °C, the UTS and hardness of the steel show a decreasing trend overall, although the UTS decreases more, while the hardness only slightly decreases.

In this subject an increasing trend was observed in recent years, focusing on thermal conductivity, temperature distribution, heat flux analysis, water system temperatures, setpoint optimization, and energy consumption reduction [ 9 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ].

The relationship between micro-pore structure and compressive strength suggested that with the decrease of open porosity, the compressive strength showed an increasing trend.

Meanwhile, as the initial concentration gradually increased, the concentration of sodium ions rose and the viscosity of the solution increased, so that the content of each impurity in the product showed an increasing trend after the concentration exceeded 60 g L −1 . 3.1.2.

Though the difference between the number of breaks in the fibre appears small, a t -test shows that it is still highly significant.

With increasing hydration time, the compressive strength of the specimens shows an increasing trend.

With the increase of sintering temperature and sintering time, the microhardness of the specimens showed an increasing trend.

The chloride concentration in sea-exposed samples after 6 months exposure did not show an obvious trend as a function of the depth.

The comparison of the probing pocket depth mean values (mean PPD) of M2′s distal aspect (distolingual, middistal, distobuccal) at times T1, T90 and T180 showed a positive trend in all parameters, recorded both at the experimental and the control sites ( Table 1 ).
