Brittle–ductile transition during diamond turning of single crystal silicon carbide [PDF]

, 2013
In this experimental study, diamond turning of single crystal 6H-SiC was performed at a cutting speed of 1 m/s on an ultra-precision diamond turning machine (Moore Nanotech 350 UPL) to elucidate the microscopic origin of ductile-regime machining ...

Atomistic aspects of ductile responses of cubic silicon carbide during nanometric cutting [PDF]

, 2011
Cubic silicon carbide (SiC) is an extremely hard and brittle material having unique blend of material properties which makes it suitable candidate for microelectromechanical systems and nanoelectromechanical systems applications.

Analysis of Ductile-to-Brittle Transition Temperature of Mild Steel [PDF]

, 2021
The Ductile-to-Brittle Transition Temperature (DBTT) is a phenomenon that is widely observed in metals. Below critical temperature (DBTT), the material suddenly loss ductility and becomes brittle.

Rheological transitions in the middle crust: insights from Cordilleran metamorphic core complexes [PDF]

Solid Earth, 2017
High-strain mylonitic rocks in Cordilleran metamorphic core complexes reflect ductile deformation in the middle crust, but in many examples it is unclear how these mylonites relate to the brittle detachments that overlie them.

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 ...

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.
