The isothermic annealing of bainite

Canadian Metallurgical Quarterly, 1975
AbstractBainitic high carbon steel has been isothermally annealed in the temperature range, 823–973K, in order to follow changes in structure and mechanical properties. The kinetic data for carbide coarsening were found to be in substantial agreement with the Ostwald ripening theory at the higher annealing temperatures. The observed divergence from the

Isothermal annealing of arsenic-implanted silicon

Journal of Physics C: Solid State Physics, 1974
Isothermal annealing studies of arsenic-implanted silicon have been made at temperatures above 550 degrees C for a dose below the amorphization limit. The process appears to follow first-order reaction kinetics with an activation energy of about 1 eV in the temperature range 550-850 degrees C.

Isothermal Annealing of Boron Implanted Silicon

Physica Scripta, 1974
The sheet resistivity has been measured in isothermal annealing studies of 10 kohm cm silicon implanted with 40 keV boron ions. The doses used were 2 x 1012 and 2 x 1014 ions/cm2. The annealing was performed in the temperature range 300 to 800°C and the maximum annealing time used was 4 hours at each temperature.

The isothermal annealing of boron implanted silicon

Radiation Effects, 1971
Abstract Isothermal annealing studies of boron implanted silicon have been made at temperatures above 600°C for boron doses in the range of 1014 to 1015 ions/cm2. A 5 eV activation energy is obtained in the temperature range 600°C to 900°C. This value is the same as that associated with the generation and subsequent migration of vacancies in silicon ...

The rapid isothermal annealing of tantalum silicide

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1985
Abstract Silicon-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 ...

Isothermal and non-isothermal crystallization of PP: effect of annealing and of the addition of HDPE

Polymer, 1998
Abstract In this report, we present the results of our investigation into the crystallization behaviour of polyproplene. The crystallization process was followed by hot-stage optical microscopy, differential scanning calorimetry, and dynamic mechanical methods. As well, nuclear magnetic resonance spin-spin relaxation techniques were employed to probe

An EBSP study of isothermally‐annealed cold‐rolled nickel

Microscopy Research and Technique, 2004
AbstractScanning 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, 1995
Porcelain 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 of saw chains

Metal Science and Heat Treatment, 1966
1. 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 ...
