WebSep 7, 2024 · The study offers fundamental insights into the deformation mechanism of BCC metals. Abstract Body-centered cubic metals including steels and refractory metals suffer from an abrupt ductile-to-brittle transition (DBT) at a critical temperature, hampering their performance and applications. WebMay 30, 2024 · The ductile–brittle transition temperature (DBTT) was also investigated and the corresponding fractograph was obtained. The DBTT of the 3Mn–Si–Ni steel is −50°C. With the temperature decreased...

WebApr 1, 2024 · According to the critical dislocation density criteria ( ρ ductile =6.51 × 10 14 /m 2 ), the DBTT for each case can be determined, as marked by the horizontal dash line in Fig. 5 (a). Here, with increasing ρ i, the DBTT shifts to the lower temperature range. WebCharpy impact test. In materials science, the Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture. Absorbed energy is a measure of the material's notch toughness. It is widely used in industry, since it is easy to prepare ...
