Improved mechanical properties of thermoelectric (Bi0.2Sb0.8)2Te3 by nanostructuring

APL Materials, 2016
Temperature-dependent strength of Bi-Sb-Te under uniaxial compression is investigated. Bi-Sb-Te samples were produced by three methods: vertical zone-melting, hot extrusion, and spark plasma sintering (SPS).

Stress modeling for the upper and lower crust along the Anninghe, Xianshuihe, and Longmenshan Faults in southeastern Tibetan plateau

Frontiers in Earth Science
Earthquake occurrence depth in the crust is related to stress, temperature, and brittle–ductile transition, which is also near the transition depth of the upper to lower crust. The composition variation between the upper and lower crust causes remarkable

The slip-rate, state-, temperature-, and normal-stress-dependence of fault frictionKey points

Earthquake Science
The mechanics of slow-slip events and earthquakes is controlled by the constitutive behavior of rocks in active fault zones, which is sensitive to many factors encompassing lithology, temperature, confining and pore-fluid pressure, and slip-rate, among ...

Heat and extension at mid- and lower crustal levels of the Rio Grande rift [PDF]

The process by which large amounts (50 to 200 percent) of crustal extension are produced was concisely described by W. Hamilton in 1982 and 1983. More recently, England, Sawyer, P.

On the Step Cooling Treatment for the Assessment of Temper Embrittlement Susceptibility of Heavy Forgings in Superclean Steels

Metals, 2016
When subjected to extended exposure to intermediate service temperatures, Cr–Mo steels, Ni–Cr steels, and 5% Ni steels can become embrittled, with an associated decrease in fracture toughness and a shift in the ductile-to-brittle transition temperature ...

Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...

Ductile-to-brittle transition behavior and determination method in X80 pipeline girth welds utilizing the master curve method

Hanjie xuebao
The fracture toughness distribution of X80 high-strength pipeline steel girth welds in the ductile-to-brittle transition region was systematically studied using the master curve method. According to ASTM E1921-97 Standard Test Method for Determination of

Ductile-brittle transition behavior of structural steel in fatigue crack growth under low temperature.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1986
The effects of specimen geometry, specimen thickness, stress ratio and frequency on the fatigue crack growth rate of structural steels were examined at 123 K to clarify the formation mechanism of a cleavage during fatigue crack growth, and the condition of the final fracture.
