Additionally, the specimen exhibited an increasing trend in recovery stress during the cooling process, which is attributed to the increase in both elastic modulus and recovery stress caused by the thermally induced martensitic transformation during cooling [ 49 ].

On the other hand, the recovery stress of the SWN specimen showed a decreasing trend until it reached the maximum temperature at a heating temperature of more than 200 °C, as shown in Figure 14 b.

The value of the activation energy of the AC conduction process in the grain boundaries showed an increasing trend with the increasing content of samarium ions Sm 3+ compared with undoped ceramics.

The replacement rate of RCA: F cement > F > F 0.01 , indicating that the RCA replacement rate exerts a highly significant effect on the 7 d unconfined compressive strength, which is weaker than that of cement content; c.

The results demonstrate a clear trend of increasing softening points with higher NM content, suggesting improved performance in hotter conditions.

The average corrosion rate exhibited a decreasing trend with time.

Figure 5 illustrates an increasing trend in Ca 5 (SiO 4 ) 2 (OH) 2 contents as a function of loaded wollastonite.

Moreover, quite significant differences in the course of the 2,4-D adsorption isotherms should be noted, especially in the area of lower concentrations for the three tested fractions.

Figure 10 shows that with increasing aging time, the fatigue life of modified asphalt exhibited a decreasing trend.

Also, an increasing trend is observed for the melt pool’s width with the VED.

All variables revealed an increasing trend in hydration degree as the curing age increased.

The slump measurement results are presented in Table 2 , indicating a decreasing trend in slump with increasing TNP content.

The tabulated data reveal a clear trend, a reduction in SiO 2 particle diameter leading to a significant increase in the surface area of the MCs, as expected.

In the figure, it can be clearly seen that with the increase in curing agent dosage, the proportion of coarse particles also increased significantly, and the PSD curve of the mixed soil was divided into two different phases with 10% curing agent dosage as the turning point, and in this process, the agglomeration effect of the mixed soil continued to increase, and showed an increasing trend of coarse particles and the decrease in fine particles.

After the T4 treatment, the solid solution amount of Cu in the matrix showed a trend of first increasing and then remaining stable.

The test results showed that the tensile strength was not affected much after 300 freeze–thaw cycles, but the high w/b tensile strain was affected more and showed a decreasing trend.

The frequency dependency at 20 °C is nearly constant; at 100 °C, there is an increasing trend; at low frequencies, the storage modulus increases until a constant value is reached at about 10 Hz.

As the load increases, the wear depths of both the substrate and composite coating show an increasing trend, but under the same load conditions, the wear depth of the composite coating is significantly less than that of the substrate.

The cumulative pore volume curves did not exhibit a clear trend.

It is found that along the length direction, the bainite and martensite structures decrease from the center to the edge region, while the ferrite structure shows an increasing trend.

This leads to a decreasing trend in deformation along the length of the front axle from the center to the edge.

However, the exposed area of the naked alloy exhibited a decreasing trend as the contact time increased.

In comparison with Figure 4 a, a similar phenomenon is observed in Figure 4 b; however, the separating area exhibits an increasing trend.

In the 400 °C to 500 °C temperature range, weight loss is due to the decomposition of Ca(OH) 2 , and as hydration progresses with curing age, all specimens exhibited an increasing trend in weight loss in this temperature range.

As shown in Figure 5 , the Vickers hardness of the novel alloy in the ST state was about 164 HV, while it reached about 359 HV in the SHT state, indicating that the strengthening effect of the fine γ′ particles precipitating during the standard heat treatment was extremely significant. 3.2.
