Excerpts

The strength of the Al-Si-Cu-Mg alloy showed a trend of first increase and then decrease, and the best effect was achieved when the Cd content was 0.3% [ 9 , 25 ].

However, the critical failure strain shows a decreasing trend with the increased W content.

The linear slope of yield strength with respect to strain rate shows a slightly increasing trend with increasing W content, indicating that the sensitivity of the materials to strain rate increases slightly with increasing W content.

The stress triaxiality shows an increasing trend upon continuous loading.

The CMS and TS tests both indicated an increasing trend in progress over time.

The average grain diameter exhibits a decreasing trend compared with the rail steels 1911 and 1921, which have the microstructures of reticular ferrite and pearlite.

This phase provides characteristic parameters about the cooling performance of the fabric during physical activity including cooling delay (CD; time until a negative trend of Torso surface temperature is observed), initial cooling (IC, rate of temperature reduction observed after onset of cooling), sustained cooling (SC, rate of temperature reduction during quasi-steady temperature course) and moisture update (accumulated moisture in the fabric at the end of phase 2).

The majority (12/17 (70%)) of the reports showed a positive trend and the effect estimate was in favour of PA.

It should be noted that the diffraction peaks of AFt decreased with increasing of LBD fineness levels, while diffraction peaks of C 3 A·CaCO 3 ·11H 2 O show an increasing trend, this means that during the hydration reaction process, AFt was partially converted into AFm, while CaCO 3 could react with C 3 A to form C 3 A·CaCO 3 ·11H 2 O.

Therefore, the front part of the fitting lines of Cr, Ti and Zr elements shows a decreasing trend.

As the WC size increased, the bonding between the splats improved ( Figure 4 ); thus, it exhibited an increasing trend for both the nanohardness and Young’s modulus in the cross-sections of the coatings.

With the increase of Factor E, VSI showed a trend of increasing first and then decreasing.

With the increase of PS content, CS at different ages showed an increasing trend.

Moreover, the TSR results given in Figure 5 below shows an increasing trend for mixes with fibers.

(ii) The flocculent structure in the range of >830 μm always showed an increasing trend, and the mass fraction did not decrease as the W/CM ratio increased.

In general, if a property demonstrates a negative trend in a solid, it continues in the liquid phase (density, speed of sound, etc.).

The average value of hole and crack roundness in the R zone at the selected six sections shows an overall trend of increase as the load increases, and in the R zone, the law is more pronounced at the lower sections of the specimen.

Figure 7 b shows that the area of each hysteresis curve was normalized, and the normalized cumulative hysteresis loop area showed a nonlinear increase with the increase in the number of cycles, and its growth rate showed a trend of “decrease–stable–increase”.

As illustrated in Figure 1 b, with the increase of sol ratio, the compressive strength showed an increasing and then a decreasing trend at 7 d and 28 d.

Moreover, as shown in curve (a) in Figure 14 , as the immersion time was prolonged, the short-circuit current density showed a trend of first increasing and then decreasing, reaching the maximum at 30 min.

Because the magnetic fields strength generated by the four composite rails in the launch space cancel each other out, the magnetic field strength in the middle of the launch area is weak, and the magnetic field in the middle area of the launch shows a decreasing trend as the thickness of the steel layer increases.

S5 with EAC applied in the middle-lower layers has the lowest tensile strain at the bottom of the asphalt layer and lowest tensile stress at the bottom of the base, decreasing by 11.81% and 1.54% compared to S0, respectively; however, S4 and S6 with EAC applied have an increasing trend in the upper layer.

It can be observed from the corrosion current density (i corr ) values that the corrosion resistance has shown an increasing trend when Sn content increased from 1 wt.% to 5 wt.% in Mg-Sn alloys.

Additionally, the tensile strength change curve of the QPFP showed a trend in linear function.

In addition, the line from the point to the origin in Figure 5 d shows an increasing trend, indicating that the misorientation angle increases along the AB line within P1.
