Application of a Tensile Test Method to Identify the Ductile-Brittle Transition of Caramel

Foods, 2022
During cutting of foods, tensile stresses in front of the blade are responsible for the separation of the material. Therefore, tensile tests can be helpful to gain knowledge on deformation properties related to pre-fracture cutting behavior as well as on

Temperature-dependent deformation and fracture properties of low-carbon martensitic steel in different stress states

Journal of Materials Research and Technology, 2023
The temperature-dependent ductile-brittle transition (DBT) in low-carbon martensitic steel is investigated in different stress states. To capture the effects of the stress state, tensile tests have been performed with flat specimens and three-point ...

Depth‐Dependent Slow Earthquakes Controlled by Temperature Dependence of Brittle‐Ductile Transitional Rheology

Geophysical Research Letters, 2023
The discovery of slow earthquakes illuminates the existence of a strange depth dependence of seismogenesis, which contradicts the common understanding of smooth brittle/seismic‐ductile/aseismic transition as going deeper into the earth's surface layers ...

Use of the small punch test for the estimation of ductile-to-brittle transition temperature shift of irradiated steels

Nuclear Materials and Energy, 2021
The small punch test is evaluated as a screening procedure for irradiation embrittlement of reactor pressure vessel steels. In particular, the correlation between ductile-to-brittle transition temperatures obtained from this small specimen test technique

Effect of Texture on the Ductile–Brittle Transition Range and Fracture Mechanisms of the Ultrafine-Grained Two-Phase Ti-6Al-4V Titanium Alloy

Metals, 2023
In this work, the technique of equal-channel angular pressing (ECAP) that enables producing bulk billets was used to form a UFG structure in Ti-6Al-4V alloy. A subsequent warm upsetting simulates die forging and the production of a part.

Studies of the formation and distribution of cracks and various defects on the heated tungsten plate surface during pulsed plasma flux impact

Nuclear Materials and Energy, 2023
In this work, cracking of the surface of a tungsten plate was studied using a PW-7 pulsed plasma accelerator. The surface of the tungsten plate was exposed at an energy density and plasma flux duration of 1.1 MJ/m2 and 200 μs, respectively.
