Sentence examples for Reduced toughness from inspiring English sources
Reduced toughness in this modified alloy relative to unalloyed NiAl Cr Mo) is attributed to the lack of plasticity in the precipitate-strengthened matrix and partial loss of the aligned lamellar microstructure by Hf and Si alloying.
However, a trade-off of such stiff networks is reduced toughness.
The layer-structure of LaPO4 phase and its weak bond with Gd2Zr2O7 matrix could cause the initial increase in the toughness, and the growth of LaPO4 grains might contribute to the reduced toughness.
In contrast, the wear volume and wear rate of the samples treated for 60 min were higher than those of untreated samples, presumably due to the higher hardness and reduced toughness of the samples treated for 60 min.
Compatibilization reduced toughness, but at VB contents of 15 wt% or more, both the modulus of elasticity and the tensile strength significantly increased with respect to the uncompatibilized blends.
This may be due to the maximum shear stress being closer to the film substrate interface, or reflect reduced toughness in the thicker films that are less able to deform as the substrate deforms plastically during the repetitive contact test.
Recent studies of the yttria partially stabilised zirconia porcelain interface have revealed the presence of near-interface porcelain nanovoiding which reduces toughness and leads to component failure.
At the nano-scale level, an additional effect of ageing is that collagen molecules undergo more glycation, which is likely to make bone harder and reduce toughness [117].
Reinforcement effectiveness is found to vary from reduced initiation toughness to over 100% increase in steady-state fracture toughness, depending upon the interlaminar fracture mechanisms.
Films with columnar microstructure possess residual compressive stress, low hardness and reduced fracture toughness.
Other blend compositions that did not show controlled cavitation resulted in little plastic flow surrounding the crack tip and reduced fracture toughness.
