Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Advanced Engineering Materials, EarlyView.Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Advanced Engineering Materials, EarlyView.The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy
Advanced Engineering Materials, EarlyView.A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

The specific heat of dry bone, as well as decalcified bone, obtained from bovine femur samples are measured as a function of temperature in the range 200 to 390K, using a differential-scanning-calorimetry technique. Special sample pans for volatile materials were used to provide a uniform thermal environment and to eliminate errors due to the ...

Specific heat in nonequilibrium systems
Physical Review E, 2001We propose a general framework of calculating the specific heat of the system in nonequilibrium, where the dynamics of the representative point can be separated into fast motion in a basin of energy landscape and the slow stochastic jump motion among basins. We apply this framework to gaseous hydrogen and obtain the observation time (t(obs)) dependence

Specific heat of holmium and terbium
Physica Status Solidi (a), 1979The lattice heat capacity of holmium and terbium is calculated using the frequency distribution function obtained from a lattice dynamical model for h.c.p. metals based on Keating's approach. The magnetic contribution to the specific heat of these rare earth metals is evaluated by subtracting the lattice and electronic contributions from the Cv data of
