DOI: 10.1007/s11015-018-0636-8
Abstract: The effect of structural characteristics (ferrite, ferrite + pearlite, sorbite) including morphology, size and distribution of nonmetallic inclusions of different morphology, sizes and distribution, on ductile–brittle transition in structural steels is considered. It is shown… read more here.

DOI: 10.1007/s11015-018-0652-8
Abstract: The effect of various factors (hydrogenation, segregation of phosphorus, arsenic and other elements), which reduce the cohesive strength of grain boundaries, on the ductile-brittle transition in structural steels is considered. It is shown that during… read more here.

DOI: 10.1016/j.chemgeo.2016.12.005
Abstract: Abstract The knowledge of CO2 transfer between carbonate reservoirs is a key issue to understanding climate evolution through geologic times. Convergent plate boundaries represent major zones for carbon recycling via burial of carbonates. In this… read more here.

DOI: 10.1016/j.ijpvp.2017.06.008
Abstract: Abstract The exposure of structural materials to the environment in nuclear power plants leads to aging through thermal and/or irradiation effects. One of the consequences of this aging is the shift of the ductile to… read more here.

DOI: 10.1029/2019gl085491
Abstract: The rate‐dependent mechanical response of snow is commonly believed to directly inherit the ductile‐to‐brittle transition (DBT) from the viscoplastic ice matrix. Recent work has however stressed the impact of microstructure evolution by rapid sintering during… read more here.

DOI: 10.1038/s41467-017-01931-4
Abstract: Understanding the flow of multi-phase (melt, crystals and bubbles) magmas is of great importance for interpreting eruption dynamics. Here we report the first observation of crystal plasticity, identified using electron backscatter diffraction, in plagioclase in… read more here.

DOI: 10.1134/s0020168518100096
Abstract: It has been shown by means of EBSD techique that fracture of ferritic steel in ductile-brittle transition temperature region, along with the formation of previously discribed cleavage microcracks, results in the formation of ductile microcracks.… read more here.
