Investigation Of Mechanical Properties Of Cryogenically-Treated Cast Iron Materials

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi, 2017
In this study, grey cast iron (GG 20) and nodular cast iron (GGG 40) samples were subjected to cryogenic treatment and after the treatment hardness and tensile values of the samples were examined.

Exploring structural integrity of coralline algae in response to the environmental changes associated with the PETM: a tale of functional resistance

open access: yesPalaeontology, Volume 69, Issue 1, January/February 2026.
Abstract Coralline algae are key benthic components of shallow‐marine ecosystems globally and as habitat‐formers they support high biodiversity levels. Experiments on living coralline algae show internal growth changes in response to warming and higher CO2.

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Effect of Temperature on Ausferritic Nodular Cast Iron Microstructure [PDF]

open access: yes, 2014
The work presents the results of the studies of the effect of the temperature on the microstructure of ausferritic nodular cast iron. The ausferrite in the matrix was obtained by way of a specific combination of molybdenum and copper.

Microstructural optimization of unalloyed ductile cast irons with a ferritic matrix used in the manufacture of wind turbine rotors [PDF]

open access: yes, 2018
The aim of this work was the microstructural optimization of cast irons with nodular graphite for the manufacture of wind turbine hubs, paying preferential attention to the geometry and distribution of graphite spheroids to ensure the required mechanical

Protracted intercontinental aridification preserved within the early Late Cretaceous strata of the Eastern Gobi Basin, Mongolia

open access: yesSedimentology, Volume 73, Issue 1, Page 147-185, January 2026.
ABSTRACT Mongolia's Eastern and Western Gobi Basins preserve a globally significant record of Cretaceous terrestrial vertebrates, yet their biostratigraphic correlations are complicated by a complex geological history. The Eastern Gobi Basin, a northeast‐southwest trending fault‐bounded rift system, includes several minor sub‐basins with distinct ...

X‐Ray Computed Tomography Quantifies Primary Phases and Reveals Crack Morphology in High‐Cycle Fatigue of Aluminum Alloy EN AW‐2618A

open access: yesAdvanced Engineering Materials, Volume 27, Issue 24, December 2025.
Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Influencia del cobre en la transformación Gamma-Alfa en la fundición gris y nodular-templabilidad [PDF]

open access: yes, 2011
This research refers to the grey iron lamellar graphite casting and nodular cast iron casting. Both contain variable percentages of copper to a maximum of 4%, cooled in sand molds in which the apparent solubility of copper is limited, to obtain wear ...
