Serrated flow behaviors in a Ni-based superalloy
Materials Research Express, 2021 Serrated flow behaviors in Ni-20Cr-18W alloy were studied under different deformation conditions. It was found that there are no serrations observed on the tensile curves of the alloy at the temperature of lower than 250 °C and the strain rate of 10 ^−3 ...

Effect of strain rate on serrated load of indentation in Al-Mg alloy
Nihon Kikai Gakkai ronbunshu, 2017 Indentation tests are used to determine the local mechanical properties of materials. Previously, the indentation strain rate was correlated with the strain rate in uniaxial tests based on the hardness, which was the obtained load divided by the cross ...

Morphological Variations of Leading-Edge Serrations in Owls (Strigiformes). [PDF]
PLoS ONE, 2016 Owls have developed serrations, comb-like structures, along the leading edge of their wings. Serrations were investigated from a morphological and a mechanical point of view, but were not yet quantitatively compared for different species.

Study on serration flow and dynamic strain aging of Cr–Ti–B low-carbon steel
Journal of Materials Research and Technology, 2021 Compression tests were carried out for hot-rolled Cr–Ti–B low-carbon steels with different Cr contents (low Cr and high Cr) at three strain rates (0.01, 0.1 and 1 s−1) and temperatures ranging from 250 to 650 °C.

Serrated polyps of the colon [PDF]
F1000 Medicine Reports, 2010 Until recently, colonic polyps were traditionally classified as either hyperplastic or adenomatous, and only the latter were believed to have the potential to progress to carcinoma. However, it is now appreciated that a subset of serrated polyps also appear to have malignant potential.

The Turkish Journal of Gastroenterology, 2020 Background/Aims: TSAs, despite their low incidence in colorectum, may originate in other parts of gastrointestinal (GI) tract, including stomach and small intestine. Malignant transformation for upper GI TSAs has recently been reported in the literature.
