Fracture toughness and deformation of titanium alloys at low temperatures

Metallurgical Transactions, 1970
Experimental data concerning the influence of compositional, microstructural and textural variations on the fracture toughness and deformation kinetics of α and α-β titanium alloys are presented. In particular, the influence of these parameters on the thermal and athermal components of the flow stress is compared to their influence on fracture ...

Fracture toughness of polymer-modified asphalt concrete at low temperatures

Canadian Journal of Civil Engineering, 2003
The fracture toughness of asphalt concrete increases at low temperature and then decreases at temperatures below a certain level. Some polymers are known to have the property of improving the temperature susceptibility of asphalt binder at low temperatures.

Study on fracture toughness of carbon-carbon composites at low temperatures

Materials Today: Proceedings, 2022
Abstract Carbon-carbon composites (C-CC), employed as composites in space and other industries for their outstanding properties. In extreme temperatures, the C-CC has proved to be the most efficient material. C-CC is one of the top thermal quality high-temperature materials such as high-temperature stability, excellent thermal conductivity, and low ...

Variation of fracture toughness of asphalt concrete under low temperatures

Construction and Building Materials, 1997
Abstract This study presents the results of experimental evaluation on fracture toughness of asphalt concrete at various low temperatures (from −5°C to −30°C in 5°C steps). An asphalt cement, penetration grade of 85/100 and two aggregates, a granite and a limestone, were used to prepare asphalt concrete beam specimens which were conditioned using two

Structural Turbulence of Pearlitic Steel 09G2S at Low-Temperature Impact Toughness

Physical Mesomechanics, 2020
The study explores the effect of helical rolling on the low-temperature impact toughness of pearlitic steel 09G2S. Helical rolling in two modes was performed at T = 850°C in six passes through rolls of varied diameters with air cooling (mode I) and water quenching (mode II).

Equipment for fracture toughness testing of specimen at low temperatures

Strength of Materials, 1988
1. Equipment was developed and the test procedure proposed for fracture toughness testing compact specimens of structural materials in off-center loading at low temperatures down to 4.2°K. 2. The strain gauges and dynamometer operating-directly in the cryogenic liquids were produced and calibrated at various temperatures.

Enhanced low temperature toughness of Al2O3-ZrO2 nano/nano composites

Nanostructured Materials, 1997
Abstract There are reports in the literature that dense nanocrystalline ceramics may be ductile at room temperature, leading to enhanced processibility and reliability. However, in spite of vigorous scientific and commercial developments in the field for the last decade, there is still controversy regarding enhanced low temperature toughness in dense

Low-temperature fracture toughness of a heat-treated mild steel

Journal of Materials Engineering and Performance, 1995
Specimens from a 0.14 % C mild steel were austenitized at 1000 °C for 1 h and thereafter furnace-cooled or isothermally transformed at 700 °C for 0.5,2, and 8 h. The microconstituents present in the as-received material were ferrite and pearlite and their amounts did not substantially change even after heat treatment.

Low-temperature fracture toughness of some iron, nickel-based metallic glass ribbons

Journal of Materials Science, 1987
The critical stress intensity factor of Fe40Ni40B20, Ni80Si10B10 and Ni80Si5B15 metallic glass ribbons was measured at temperatures 4.2 to 300 K. The low-temperature embrittlement for Ni-Si-13 glasses was not investigated. The low-temperature embrittlement of Fe40Ni40B20 glass depends on the structural relaxation and is connected with a change from ...
