Binary Zr-alloys containing 1%Fe and 1% Ni (large precipitates) and 1% Cr and 0.6% Nb (small precipitates), as well as a pure Zr sample were exposed in situ at 130 Pa water vapour pressure at 415 °C in an environmental SEM. The surface topography an

C60 fullerene reacted with phosphorus at high temperatures to graphitic materials with strongly differing properties. Several spectroscopic investigations as Raman, ESR, XPS and 31P-NMR as well as TEM and ESEM have shown that the structural order of

Dislocation pinning processes have been examined by studying strain-ageing effects in a range of γ-TiAl alloys. The yield stress increase after static strain ageing is shown to depend on the prior strain imposed before the ageing step and the time a

In general, plastic deformation of ordered alloys can reduce the degree of long-range order. This phenomenon has been observed in Ni[sub 3]Al. It has been shown that during mechanical milling of this alloy, the long range order parameter decreases wi

Samples of Fe28%Al and Fe28%Al4% Cr were recrystallized, and heat treated at 500°C to obtain B2 and DO3 ordering. While the material containing Cr was well ordered, and other material showed a two-phase ordered plus disordered microstructur

It has previously been shown that the addition of Cr to the Fe3A1 alloy can lead to improvements in ductility. Initial interpretations of this effect were based on changes in the fault energies and dislocation configurations, but recently the influen

The development of Fe 3 Al aluminides has been restricted in the past by poor ductility at ambient temperatures, and it is only recently that possible solutions to this problem have been found. It was shown a few years ago (1) that the addition of 2-
