Excerpts

The next section of the results was concerned with the increase of Na-beidellite and non-lyophilized Beta zeolite contents, and elongation at break of the composites, while a decreasing trend was recorded in tensile strength from 2.3 to 2 MPa, and from 2.0 to 1.5 MPa, respectively, as well as their Young’s modulus, which was 35 to 20 MPa and 20 to 15 MPa, respectively.

For the first four samples, a decreasing trend in the viscosity of the samples with the increase in the filler content could be seen as the MFR value increased.

The significance tests of the three models were p < 0.001, indicating extremely significant and high reliability of the three models.

However, in recent years, there has been an increasing trend in producing different zirconia objects thought AM techniques (3D printing) [ 16 ].

With increasing water erosion time, the crush resistance of steel slag before and after treatment showed a decreasing trend, but the abrasion and crush value of treated steel slag gradually became stable.

For instance, the temperature difference at different speeds was in the range of 12.3–17.9% and showed an increasing trend with increasing speed.

The friction coefficient analysis at the tool–chip interface at different cutting speeds indicated a decreasing trend of friction coefficient in the order of AS (conventional), AT-PE (linear grooves perpendicular), AT-PA (linear grooves parallel) and AT-W (wavy grooves) tools, Figure 6 .

Therefore, I OFF exhibits an increasing trend.

With increasing strain rate, the DRX grain size decreased rapidly, while the DRX volume fraction showed a trend of first increasing and then decreasing.

(2) The strain rate sensitivity of 316L exhibits an interesting trend, in that it is generally low (0.1–0.2) at 700–900 °C but increases to 0.33, at 45% strain at 1000 °C.

However, at 1000 °C, there is an increasing trend for the strain rate sensitivity, which increased from 0.15 at a strain level of 20% to 0.33 at a strain level of 45%.

A negative trend in OCP with time (towards more negative values) indicates a tendency for the metal/surface to corrode in the solution, while a less negative OCP (reverse trend) indicates a low tendency for corrosion, indicates the formation of a protective layer (passive layer), or demonstrates the stability of the previously formed protective layer. 3.2.1.

The resistance values for all modified surfaces showed an increasing trend.

The adsorption capacities of Zn−AC, Cu−AC, and Fe−AC showed a decreasing trend with the increase in the initial pH value.

(2) With the increase of the p parameter, the distribution error shows a decreasing trend, and the peak value error remains unchanged or decreases.

Since Vickers hardness tests are always carried out on an area of microstructure, it must be assumed that these stochastically distributed ferrite or martensite grains influence the recorded hardness value, which explains the partially significant standard deviations of the measured values after the tempering tests or even generally irregular results as demonstrated by Figure 11 .

Thus, the COF of the wire rope shows a decreasing trend in this process.

It was not possible to identify a clear trend for the failure mechanism of either the tests performed at high cross-head rate or under impact conditions.

In using laser cladding to apply HEACs, there are still large blind zones, and the development of the parameters is theoretically and practically significant.

Overall, with the increasing C 0 , the value of Q e shows an increasing trend until keeping stable, while R e tends to decrease until it is stable.

The horizontal stresses measured along V-1 and V-3 both reduced with a decreasing trend as the distance from the tunnel increased.

It could be seen from Figure 6 that the β t content presents an increasing trend as EPT voltage increases.

While the yield strengths of the EPT8 and EPT9 samples are 726 MPa and 771 MPa, exhibiting a decreasing trend generally, which could be attributed to the decrease of α p and the increase of β t [ 11 ], the EPT8 sample possesses the lowest yield strength, which is corresponding to the highest area fraction value of β t .

Results and Discussion Figure 2 shows the principal strain cloud map of D1 at different loading stages, when the compression load attained 20% to 60% F max (the max value of pressure during loading), the principal strain presented a decreasing trend from the loading end to the fixed end.

Both 28d flexural strength and 28d compressive strength showed a trend of increasing and then decreasing with the increase in SP amount.
