Examination of Ni-base superalloy diffusion couples containing multiphase regions
(2014-04-02)Four Ni-base superalloy diffusion couples with multiphase regions were studied. The diffusion couples contained single-phase (gamma ), two phase( gamma +MC carbide) and three-phase ( gamma + gamma prime+MC carbide) ... -
Interdiffusion in the Mg-Al System and Intrinsic Diffusion in beta-Mg2Al3
(2013-05-07)Solid-to-solid diffusion couples were assembled and annealed to examine the diffusion between pure Mg (99.96 pct) and Al (99.999 pct). Diffusion anneals were carried out at 573 K, 623 K and 673 K (300 C, 350 C and 400 C) ... -
Interrelationship between the Diffusion Behaviour and the phase Transformation Characteristics
(2013-07-03)It has been observed that the metals which exhibit anomalous diffusion behaviour are all allotropic in nature. A hypothesis to rationalise this interrationship between the diffusion behaviour and the phase transformation ... -
Mg Self-Diffusion
(2013-08-09)The self-diffusion of magnesium along the c-axis and perpendicular to it has been investigated in the temperature range from 500 to 630 C. -
Mg Self-Diffusion
(2013-08-09)The determination of the self-diffusion coefficient of magnesium has been made possible recently by discovery of a radioactive isotope, Mg-28 having a half-life of 21.3 hr, and subject to manufacture in useful quantity. -
Mg Self-Diffusion Pavlinov 1968
(2013-08-29)It is found that the parameters of self-diffusion and carbon diffusion in calcium are in good agreement with the general regularities for self-diffusion in pure metals and interstitial impurity diffusion in metals with a ... -
Mg-Al Interdiffusion and Phase Growth Kinetics
(2013-05-07)Binary interdiffusion data as functions of composition in the Mg-Al system are essential in modeling kinetics of phase transformations in multicomponent Mg and Al alloys. Interdiffusion and phase growth kinetics were studied ... -
Ni Self-Diffusion
(2013-06-26)Self-diffusion in nickel single crystals is measured between 813 and 1193 K using ion-beam sputtering as a microsectioning technique. Gaussian activity-depth profiles are observed over about three orders of magnitude in ... -
On the Anomalous Self-Diffusion in B.C.C. Titanium
(2013-07-03)Self-diffusion of the Ti44 is measured in Beta-Titanium under UHV conditions int eh whole range of existence of the bcc phase. The Arrhenius plot shows a strong upward curvature in agreement with previous investigations ... -
Self-Diffusion and fast cobalt impurity diffusion in the bulk and in grain boundaries of hexagonal titanium
(2013-07-03)Bulk Self-Diffusion was measure in alpha-Titanium single crystals between 776 and 1132 K using the radiotracer Ti44 and ion beam sputtering for profile sectioning. -
Self-diffusion in aluminum at low temperatures
(2014-01-20)Values of the self-diffusivity of pure aluminum in the temperature range 130∮ to 200° have been determined by measuring the rate of annealing of prismatic and faulted dislocation loops in thin foils of quenched 99.999 pct ... -

Study of Si self-diffusion by nuclear techniques
(2014-02-10)By using ion implantation for preparation and p, γ-reactions for analysis of 30Si profiles the Si self-diffusion has been studied in the temperature range of 830–1200°C. The results reveal unambiguously that the diffusion ... -
