Excerpts

However, as the environment changed from a room temperature environment to a simulated seawater environment, the necking phenomenon gradually weakened, the section shrinkage rate showed a decreasing trend, and the brittleness increased.

Hence, the 57.9% reduction in wear volume observed in this study within the same timeframe is highly significant.

The parameters Str and Spc did not show a clear trend of changes.

The lattice parameter, determined using the Nelson–Riley (N–R) extrapolation method, showed an increasing trend with higher Zr 4+ content, which can be attributed to the larger ionic radius of Zr 4+ (0.86 Å) compared to Cr 3+ (0.755 Å).

With an increase in the RCA substitution rate, the compressive strength of pervious concrete showed a trend of first increasing and then decreasing, while the permeability coefficient tended to decrease and then increase, which was similar to most research conclusions [ 17 , 18 ].

The solubility of water in the insulating oil of PXE power capacitors exhibits an increasing trend with rising temperatures.

The width of the lamellar α also shows a decreasing trend.

As shown in Figure 13 , the results show that from the bottom to the top of the cladding layer, the temperature gradient and shape control factor show a decreasing trend, while the solidification rate and cooling rate show an increasing trend.

Another parameter that defines the TFT performance is a sub-threshold swing (SS), which shows a decreasing trend from RT to high-temperature deposition.

When the given wire feeding speed was consistent, the arc width showed a decreasing trend as the welding speed increased from 180 cm/min to 240 cm/min.

As the rotation speed increased (450, 500, and 550 rpm), the grain size showed an increasing trend (7.2 ± 0.6 μm, 7.4 ± 0.5 μm, and 7.7 ± 0.3 μm, respectively), and the kernel average misorientation showed a decreasing trend (5.0, 4.8, and 4.3, respectively), as shown in Figure 24 [ 40 ].

In terms of mechanical properties, the results are summarized in Figure 25 ; as we can see, strength (YS and UTS) showed a decreasing trend, but the EL showed a slightly increasing trend [ 40 ].

However, after 6 months of exposure, if the exposure time continues to be extended, the elongation and area reduction of WE43 alloy do not continue to show a decreasing trend, indicating that the impact of corrosion behavior on the plasticity of WE43 is mainly concentrated in the early stage of corrosion.

After 10,000 h of service, the fracture showed a trend of intergranular fracture ( Figure 2 b), with small dimples and numerous secondary cracks visible on the grain surface at high magnification ( Figure 2 e).

With the increasing MOF dosage, the R of Cr(VI) showed a trend of increasing at first and then flattening.

A clear trend of increasing impact strength of the injected samples can be observed for samples containing POE elastomer (1MAPP/POE= 31 kJ/mol; 2 MAPP/POE = 18 kJ/mol; 3 MAPP/POE= 11 kJ/mol) in relation to unmodified samples (cPP = 7 kJ/mol).

Both sets of experiments exhibit a decreasing trend in the angle of repose with increasing distance from the headwater, although the exact slopes and curvatures of the simulation and experimental curves differ.

Hence, the relationship between the unit weight of plastic-modified mixtures and plastic aggregate content is linear with a decreasing trend [ 5 , 133 ].

As seen in Table 2 , physically activated carbons showed a decreasing trend in mass yields as the activation temperature and residence time increased.

The stress sensitivity of asphalt binder shows an increasing trend with the increase in fiber dosage, indicating that fiber is conducive to improving the stress sensitivity of asphalt binder.

The thermal conductivity of the investigated alloys without heat treatment ranges from approximately 125 to 138 [W·m −1 ·K −1 ] at 50 °C and shows an increasing trend as a function of temperature (50–300 °C).

TEM analysis revealed that core-to-fiber diameter ratio shows an increasing trend with increasing HA content.

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

A clear trend for a transmittance reduction with increasing acoustic stimulus frequency is observed for all compositions.

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