Isothermal annealing of saw chains
Metal Science and Heat Treatment, 19661. Isothermal annealing of 85KhF (85Kh) and ShKh15 steels to a hardness of HRC 48-55 increases the toughness almost twice (by comparison with quenching and tempering to the same hardness). 2. With isothermal annealing the hardness of 85KhF and ShKh15 steels (links of saw chains, for example) can be increased by 5–6 HRC units without ...

Isothermal Anneal Effect on Leucite Content in Dental Porcelains
Journal of Dental Research, 1995Porcelain thermal expansion behavior is a function of leucite content, and leucite changes can produce porcelain-metal incompatibilities. The purpose of the present study was to determine whether isothermal anneal treatments (such as are encountered during "post-soldering" operations) could result in alterations of leucite content of dental porcelain.

An EBSP study of isothermally‐annealed cold‐rolled nickel
Microscopy Research and Technique, 2004AbstractScanning electron microscopy and electron backscattered patterns, EBSP, have been employed to reveal both the grain structure and texture of 90% cold‐rolled polycrystalline nickel after 1‐hour anneals at a variety of temperatures. After annealing at either 400° or 500°C, small, cube‐oriented, equi‐axed grains were produced via primary ...

Isothermal Annealing Effects in Irradiated Copper
Physical Review, 1953Copper wires were bombarded with 12-Mev deuterons at low temperatures. The wires were then allowed to anneal isothermally at successive temperatures from -185\ifmmode^\circ\else\textdegree\fi{}C to +167\ifmmode^\circ\else\textdegree\fi{}C. Recovery of the electrical resistivity increase, produced by the bombardment, was observed at all temperatures ...

Isothermal Magnetic-Annealing Experiments on Substitutional Alloys
Journal of Applied Physics, 1967Isothermal magnetic-annealing experiments were carried out by means of torque measurements on a Ni(Fe) alloy containing 16% Fe and on Fe(Si) alloys with concentrations between 2.7 and 7.9 at. %Si. The measured torques showed an approximate exponential time-dependence in approaching equilibrium.

Short-term isothermal annealing of polyethylene single crystals
Journal of Applied Physics, 1985Polyethylene single-crystal mats 20 μm thick were heated to the annealing temperatures (120–132 °C) in less than 1 s. The Cornell High Energy Synchrotron Source (CHESS) and a TV detector system were used to obtain wide- and small-angle x-ray scattering patterns from these mats during annealing with a time resolution of 0.3 s.

• Evolution of aluminum grain boundaries during isothermal annealing
Deformation and Fracture of Materials, 2023Using an example of textured aluminum foils, the possibilities of using the reflected electron diffraction method for in situ studies of the behavior of grain boundaries during isothermal annealing have been experimentally demonstrated. It is shown that there is no homogeneity of the microstructure in space and no continuity of its change in time ...

Electronic Defects in Silicon after Transient Isothermal Annealing
MRS Proceedings, 1983ABSTRACTWe have investigated trap levels in silicon after Thermal Pulse Annealing (TPA). Three different annealing systems consisting of tungsten lamps or a graphite heater have been applied. Trap levels induced in different silicon materials (Cz, FZ, Epi) after TPA have been studied by DLTS and admittance spectroscopy. In boron-doped epitaxial silicon

Isothermal annealing of cold-rolled high-purity nickel
Materials Science and Engineering: A, 2008Abstract Electron backscattered patterns have been employed to reveal the details of the texture evolution in 90%, 95% and 97.5% cold-rolled, polycrystalline, high-purity nickel specimens after 1 h anneals at a variety of temperatures. The results show that increasing the thickness reduction of cold-rolling both strengthened the cube texture ...

Graphite strip rapid isothermal annealing of tantalum silicide
Journal of Applied Physics, 1984Silicon-poor tantalum silicide films cosputtered on polycrystalline silicon over thermal oxide on silicon were rapidly annealed for various temperatures and times using a graphite strip heater. Rutherford backscattering and x-ray diffraction showed rapid formation of a stoichiometric tantalum disilicide via Si diffusion from the polycrystalline Si ...
