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 ...

DSC Behaviour of Isothermally Annealed Fibres
1980The DSC behaviour of both polyamide and polyester fibres after an isothermal annealing process was investigated in our previous papers(1),(2). Some thermal process was to be observed in the temperature region between Tg and Tm. The position of this thermal process is related to the annealing temperature.

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 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 ...

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 ...

Rapid isothermal anneal of 75As implanted silicon
Applied Physics Letters, 1982Silicon wafers implanted with 75As have been annealed with a Varian IA-200 isothermal annealer. The anneal occurs in vacuum using radiation from a resistively heated sheet of graphite. The anneal quality depends on the graphite heater temperature and exposure time.

Study on Co∕Pt Multilayer with Isothermal Annealing
AIP Conference Proceedings, 2011Co/Pt multilayer system has been grown using Ion beam sputtering process. The multilayer system has been vacuum annealed at various temperatures. The structural and magnetic properties have been investigated by using X‐ray reflectivity, X‐ray diffraction and magneto optical Kerr effect. It has been observed that thermal annealing results in the partial

Isothermal Annealing of Space Charge in MNOS Structures
physica status solidi (a), 1986The influence of X-ray irradiation on the stationary conductivity and isothermal depolarization of MNOS structures is studied. It is shown that low-temperature annealing of radiated MNOS structures without bias voltage increases activation energy under isothermal depolarization from EA = 0.8 eV up to EA = 1.4 eV.

Deformation and isothermal annealing behaviour of nickel
British Journal of Applied Physics, 1967Isothermal annealing of cold-worked nickel produces softening which initially occurs exponentially but which is followed by a sigmoidal stage. A theory of isothermal softening behaviour, based upon polygonization of subgrains, is presented.
