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.

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.

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.

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 annealing of oxygen decorated defects in silver
Hyperfine Interactions, 1983The dynamics of trapping and detrapping processes of oxygen decorated radiation defects in silver were investigated by the TDPAC technique. Three defect clusters containing In, oxygen and vacancies were studied by isothermal annelaing experiments between 250°C and 450°C.

Acceleration of final cooling of forgings in isothermal annealing
Metal Science and Heat Treatment, 19841. The temperature differential in a charge in final cooling of forgings is determined by the difference in cross sections of the forgings, the point of their location in the furnace, and the allowable specified rates and method of cooling. In the case of location of forgings with thin sections at the charging door in acceleration of the process of ...

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

Polysilicon Grain Growth by Rapid Isothermal Annealing
MRS Proceedings, 1984ABSTRACTone method of reducing the area occupied by a RAM cell is to stack the p- and n-channel devices on top of one another. This “stacked CMOS” structure is a first step towards three dimensional integration. The simplest approach is to use polysilicon as the substrate for the top transistors. This paper describes the results of grain growth studies

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.

Isochronal and Isothermal Annealing of Wrought Aluminum Alloy
Defect and Diffusion Forum, 2011Positron annihilation lifetime (PAL) is one of the most important nuclear techniques used in material science. Electrical measurements are also used in material science. Samples of 25 % deformation have been used for these studies. Both positron annihilation lifetime and electrical measurements were used to determined the activation energy of migration
