管道保护During CO2 leakage, the Joule-Thomson effect and operational factors such as throttling and venting can cause the local temperature of the pipeline to drop abruptly to -78.5 ℃, significantly increasing the risk of brittle fracture.

Hump on upper shelf of ductile—brittle transition temperature curve of a plain carbon steel [PDF]
Materials Science and Technology, 2011 The ductile—brittle transition temperature (DBTT) in a plain carbon steel has been studied in a series of Charpy V notch samples. Both non-standard and standard samples were used in the as drawn, normalised and annealed conditions. In all cases, a hump was recorded on the upper shelf of the DBTT.

Size-dependent brittle-to-ductile transition in GaAs nano-rods
, 2014 GaAs is brittle at room temperature at the macro-scale; however, ductility emerges when its characteristic dimension reduces to the nano-scale. Using molecular dynamics simulations, we reveal that there is a brittle-to-ductile transition in GaAs nano ...

AN ANALYSIS OF IMPACT TESTING OF HIGH STRENGTH LOW-ALLOY STEELS USED IN SHIP CONSTRUCTION
Brodogradnja, 2021 Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous.

Ductile-to-brittle transition in spallation of metallic glasses
, 2014 In this paper, the spallation behavior of a binary metallic glass Cu50Zr50 is investigated with molecular dynamics simulations. With increasing the impact velocity, micro-voids induced by tensile pulses become smaller and more concentrated.

Experimental investigation on the rheology of fault rocks [PDF]
, 2014 The aim of this study is to explore and identify physical and chemical processes occurring during deformation of fault rocks under elevated pressures and temperatures where an interplay between brittle/frictional and viscous processes is expected.
