Influence of grain boundary structure on discontinuous precipitation in austenitic steel

Autor: M. H. Ainsley, D. R. Miller, G. J. Cocks

Publikováno v: Metal Science. 13:20-24

Discontinuous precipitation in an austenitic Fe-Mn-V-C alloy has been studied using transmission electron microscopy of extraction replicas and thin foils. The vanadium carbide precipitates formed during the discontinuous reaction are present either

The Orientation Relationship and Morphology of Fe2Nb Precipitates in Ferrite

Autor: G. J. Cocks, D. W. Borland

Publikováno v: Metal Science. 9:384-389

The orientation relationship between ferrite and precipitate particles of the hexagonal Laves phase, Fe2Nb, has been determined using electron diffraction techniques. There exists a single orientation relationship, which may be stated as:A model of t

High-temperature fatigue cavitation in a copper alloy

Autor: D. M. R. Taplin, G. J. Cocks, A. L. W. Collins

Publikováno v: Metal Science. 11:87-90

The process of intergranular fatigue cavitation at 500°C in a copper-base alloy (CDA 638) has been studied in low-frequency tension/compression cycling. The focus has been upon the role of grain size over the range 16–330 μm average dia. Specimen

Bulge-forming characteristics of two superplastic copper alloys

Autor: G. Rowbottom, D. M. R. Taplin, G. J. Cocks

Publikováno v: Metals Technology. 3:332-337

The deformation of two industrial alloys which exhibit superplasticity (Cu-9·5Al-4Fe and Cu-0·4Co-2·8Al-1·8Si) has been examined by subjecting thin circular diaphragms to one-sided hydrostatic pressure at elevated temperatures. The experimentally

Ledge mechanism of growth of colonies of discontinuous precipitate in austenite

Autor: G. J. Cocks, R. A. Legge, D. R. Miller

Publikováno v: Metal Science. 14:480-484

A ledge mechanism of growth of colonies of discontinuous vanadium carbide precipitate in an austenitic Fe-Mn-V-C alloy has been established by observing the progress of the reaction using scanning electron microscopy. The mobility of the risers of th

On the formation of the diamond grain configuration during high temperature creep and fatigue

Autor: Vakil Singh, D. M. R. Taplin, P. Rama Rao, G. J. Cocks

Publikováno v: Journal of Materials Science. 12:373-383

A study has been made of the influence of test variables on the formation of the diamond grain configuration during high temperature creep and fatigue deformation of a wide variety of metals. The proposed mechanisms for the formation of this interest
