Effect of Repeated Loads on the Low Temperature Fracture Behavior of Notched and Welded Plates [PDF]

, 1967
The influence of repeated loadings on the susceptibility of weldments to fracture in a brittle manner is studied for an ABS-Class C steel. The test members have consisted primarily of 12, 24 and 36 in.

The design of an Fe-12Mn-O.2Ti alloy steel for low temperature use [PDF]

An investigation was made to improve the low temperature mechanical properties of Fe-8 approximately 12% Mn-O 2Ti alloy steels. A two-phase(alpha + gamma) tempering in combination with cold working or hot working was identified as an effective treatment.

Temperature-driven nanoscale brittle-to-ductile transition of the C15 CaAl2 Laves phase

Materials & Design
The influence of temperature on the deformation behaviour of the C15 CaAl2 Laves phase, a key constituent for enhancing the mechanical properties of Mg alloys up to service temperatures of 200 °C, remains largely unexplored.

Ductile–Brittle Transition Mechanism and Dilute Solution Softening Effect of Body-Centered Cubic Metals

Metals
Body-centered cubic (BCC) metals, extensively utilized in low-alloy high-strength steels and heat-resistant alloys, exhibit a pronounced ductile–brittle transition (DBT) at cryogenic temperatures, marked by a well-defined yet narrow ductile–brittle ...

Rheological segmentation of the Cocos slab and its relation with the 2017 Mw8.2 Tehuantepec earthquake

Frontiers in Earth Science
Tectonic plates bend and deform when approaching a subduction zone, creating intense faulting and highly variable stress and strain fields across short distances inside the slab.
