The results also reveal that both before and after the thermal exposure, the Ti65 alloy contains high-density and uniformly distributed spherical nanoscale α 2 phases, and the size of the α 2 phases remains initially unchanged and slightly increases later as the T e increases, while the content shows an increasing trend followed by a decrease.

Then, there was a decreasing trend in maximum amplitudes followed by an increasing trend up to the second peak, defined as stage II.

Effect of NaOH Concentration and Solid-to-Liquid Ratio As shown in Figure 4 a, the SiO 2 extraction ratio exhibited an increasing trend with the rise in the NaOH concentration.

Effect of Dilution Ratio From Figure 10 a, it can be seen that the 28-day compressive strength of MSWIBA foamed concrete showed a decreasing trend as the foaming agent dilution ratio increased.

The addition of TiO 2 to PLA caused a statistically significant decrease in the contact angle values of both the composite and the coated specimen, and a decreasing trend in the values of the composite to the coated sample.

Both the UTS and EL of the alloy showed a trend of first increasing and then decreasing.

And the lateral displacement and acceleration responses show a decreasing trend with the increase in the track beam height. 4.2.2.

At higher dopant levels, an increasing trend can be observed to 50 mol% CaO.

The admixture of casein influenced the properties of the mortar, but not in all cases, and it was possible to determine a clear trend related to the variable amount of casein.

A decreasing trend of peak current density was observed at smaller CaO content concentrations, attaining a minimum value for the sample with 12 mol%.

At three temperatures, with the increase in strain amplitude, the initial strain amplitude increases accordingly; on the other hand, the fatigue life shows a decreasing trend.

Differences were considered statistically highly significant at p < 0.01. 3.

With the increase in ultrasonic power, the fluidity of both alloys showed a trend of first increasing and then decreasing, with the effect of ultrasonic vibration on the fluidity of hypoeutectic AlSi9 alloy being more significant.

As the TiO 2 content in the slag increases, the viscosity exhibits a decreasing trend.

Specifically, as the load increases, the kinetic coefficient of friction of the composite coating shows a decreasing trend, which is the opposite of the behavior in the general metal friction-wear test.

The ternary alloys have a decreasing trend in aluminum content towards the surface as for Fe–Al binary alloy.

When SNS was added, a clear trend was observed where increasing the SNS content significantly improved the compressive strength at 1 d.

The peak intensity of CH showed an increasing trend and the peak intensity of the mineral phase (2θ 18°) of the clinker showed a decreasing trend after the addition of SNS during early curing ages.

The laboratory tests and analysis results indicate that both ultrasonic pulse velocity and amplitude in dry and wet conditions show a decreasing trend with an increase in temperature.

It can be seen that its peak intensity (2θ 18°, oval area in Figure 7 ) showed an increasing trend with increasing curing age due to the continuous hydration of the silicate phase.

When the strain rate was low, decreasing the strain rate resulted in an increasing trend in the material’s initial yield strength and work hardening exponent, while the strain hardening coefficient showed a decreasing trend. 3.

Improving the surface layer properties through shot peening can also enable the use of smaller cross-sections due to increased operational durability (caused by vibratory shot peening), which is highly significant in terms of reducing the weight of structures in the automotive and aviation industries.

In contrast, other PFC types demonstrate a decreasing trend in fatigue strength, ranging from cross-ply [0°/90°], quasi-isotropic, twill-woven reinforced, [±45°], random-oriented mat reinforced, to transverse direction [90°] configurations.

During the 14-day immersion process, the corrosion current density of the three alloys showed a decreasing trend with extension of the immersion time, indicating that the corrosion rate of the alloys gradually decreased with an increase in immersion time.

As shown in Figure 11 , with the increase in the number of salt freezing cycles, the cube compressive strength loss rate of PF 0 S 5 , PF 0.1 S 5 , PF 0.3 S 5 and PF 0.5 S 5 specimens showed a trend of decreasing first and then increasing, and the rising rate gradually accelerated.
