Meanwhile, a comparison of Figure 7 a,b reveals a decreasing trend in the resonance displacement response of the specimens as the temperature increases from 50 °C to 100 °C.

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.

For a short age of 28 days, when the GGBS content is low (10% and 20%), the compressive strength shows a slight increase, and with a further increase in GGBS content, the compressive strength shows a decreasing trend.

The results also indicated that the splitting tensile strength shows an increasing trend over time.

In Figure 14 s,t, the behavior of the homogenized transverse compressive strengths ( σ y c h ) reveals an interesting trend.

As shown in Figure 4 , after 540 cycles of rapid temperature change, the shear strength of the chip–substrate joint showed a decreasing trend.

Therefore, the alkali-activated cementitious system is highly significant for cement reduction and industrial solid waste utilization in future applications [ 24 , 25 ].

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.

Tensile type shows a decreasing trend, and the variation range is “9.24% > 8.84% > 5.89%”.

The iron powder content had a highly significant effect on σ c , σ t , τ f and c , and it had a significant effect on ν and φ .

For the AACF condition, the dimensionless number initially showed an increasing trend, then followed by a decreasing trend.

They found that the friction coefficient exhibited a decreasing trend as the sliding velocity and load increased.

It can be observed that the microhardness value exhibits an increasing trend from the substrate to the heat-affected zone and then to the coating.

Lee and Kim [ 15 ] obtained a Lorenz number of 1.54 × 10 −8 V 2 K −2 at 323 K for Cu 3 SbSe 3.2 S 0.8 , noting a decreasing trend in the Lorenz number with increasing S content.

The pore size distribution curves decrease significantly in the main peak signal, and the signal of the second peak shows an increasing trend.

(5) The number of force chains shows a decreasing trend after the cracks begin to grow.

As shown in Figure 3 b, compared with the blank group, after adding 5~15% fly ash, the strength growth rate of the cementitious materials at each age also showed a trend of first increasing and then decreasing.

Student’s t -tests yielded highly significant p -values (<0.001) for both the pellet and supernatant coefficients, falling within narrow confidence intervals (see Table 3 ).

The potential needs for nanomaterials show an increasing trend [ 4 ].
