Brittle-to-ductile transition in steels and the critical transition temperature

International Journal of Fracture, 1983
Specimens of different thickness made of a low-alloy steel were tested to determine fracture toughness under static and impact loading at room and low temperatures. It was found that for the specimen of each thickness there was a specific brittle-to-ductile transition temperature Tps defined as the upper temperature boundary up to which plane-strain ...

Evaluation of the influence of homogenization annealing on the critical brittle temperature of forged blanks from steel 15Kh2MFA-A

Voprosy Materialovedeniya, 2023
The effect of the homogenization annealing duration on the critical brittle temperature of 15Kh2MFA-A vessel reactor steel has been studied. The criterion for calculating the duration of the annealing is determined – this is the total duration of heating of the ingot and forging before the first and second removals. It is shown that in order to achieve

The critical temperature for brittle-to-ductile transition of intermetallic compound based on NiAl

Materials Letters, 2004
Abstract The brittle-to-ductile transition (BDT) behavior of NiAl–9Mo alloys was firstly investigated to occur in the small temperature range of about 10 °C using tensile test method. The characteristic temperature T AB was defined for BDT in the alloy.

Relationship of critical brittleness temperatures to the mechanical properties and fracture toughness of steels

Strength of Materials, 1989
1. Analytical relations were established which make it possible to determine the temperature Tb for standardized specimens. 2. It was shown that it is possible to use either of the known relations of(T) or KIc(T) and the value of ΔTb to find the other relation-say KIc(T). 3.

Critical temperature of brittle failure in induction-hardened steel

Metal Science and Heat Treatment of Metals, 1962
1. For specimens quenched after induction heating we obtained a wider range of optimum tempering temperatures producing maximum impact toughness (180–240°). In this heat treatment the temper brittleness zone is narrowed down. 2. The impact toughness of induction-hardened 45KhTR steel at a test temperature of 20° is approximately 20 ...

Effect of chemical and structural nonuniformity of vver vessel steel on the critical brittleness temperature under irradiation

Atomic Energy, 2012
More accurate modeling of the radiation embrittlement of a calibration metal on the basis of the shift criteria and envelopes of the dose–time dependences experimentally confirms that the modeling error corresponds to the variance band limits of the results of tests performed in control samples and reflects the structural nonuniformity of the metal of ...

Theory of ductile-brittle transition in steels and iron alloys: Theory of stress dependence of the critical temperature of ductile-brittle transition

Doklady Physical Chemistry, 2008
The author deduces required dependence on the ground of consideration of thermodynamic potential at ductile-brittle transition under stresses, having assumed power dependence of coefficients on temperature. Calculated results are compared with the Moessbauer spectra observations.

Critical crack size for low-temperature brittleness of mild steel in tension of center-cracked sheet

Materials Chemistry and Physics, 1990
Abstract The present paper deals with the fracture behavior of mild steel vs temperature using experimental results of a center-cracked sheet in tension at various temperatures. It is indicated that, for this specimen geometry and loading mode, there also exists a critical crack size for the occurence of low-temperature brittleness, ac, below ...
