Understanding the tensile ductility of a novel low-activation BCC high-entropy alloy deformed at intermediate temperature

open access: yes
Low-activation body-centered cubic (BCC) high-entropy alloys (HEAs) often possess poor tensile ductility. Here we report a novel low-activation VCrFeMn0.33 BCC HEA that exhibits good tensile ductility at 650 °C and above.

Ductile-Brittle Transition Temperature shift controlled by grain boundary decohesion and thermally activated energy and hydrogen GB embrittlement [PDF]

open access: yes, 2018
Classical structural problems of temper embrittlement are evaluated in terms of changes in the ductile-brittle transition temperature (DBTT). Experimentally, DBTT is not only strongly dependent on the effects of the type and amount of segregated solute ...

Effects of deformation-induced martensite and grain size on ductile-to-brittle transition behavior of austenitic 18Cr-10Mn-N stainless steels

open access: yes, 2010
Effects of deformation-induced martensite and grain size on ductile-to-brittle transition behavior of austenitic 18Cr-10Mn-(0.3 similar to 0.6)N stainless steels with different alloying elements were investigated by means of Charpy impact tests and ...

Examination of the effect of tin particles and grain size on the charpy impact transition temperature in steels [PDF]

open access: yes, 2012
The toughness of ferritic steels is influenced by the grain size distribution, second phase, precipitates and coarse inclusions. In this work an examination of the effect of coarse TiN particles (> 0.5 \(\mu\)m) and ferrite grain size on the Charpy ...

Analysis of Ductile-to-Brittle Transition Temperature of Mild Steel

open access: yes, 2014
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.
