The effect of nickel on two classes of martensitic-type transformations in platinum systems has been studied. The first transformation is Ll 2 to DO c ' in the Pt3Al system and the second is B2 to B 19 in the TiPt system. The microstructures after tr

Synchrotron x-ray diffraction studies up to pressures of 30 GPa have been performed on both nanostructured γ-Al2O3 and α-Al2O3. The P-V equation of state has been calculated from a fit to the diffraction data to obtain the compressibility for each

The TiPt phase with the B2 structure has been reported to undergo a reversible displacive transformation to B19 martensite at about 1000 °C. This system could, therefore, serve in principle as the basis of a high-temperature shape-memory alloy (SMA)

The platinum-rich region of the Pt-Al-Ru system was investigated with a view to stabilizing the displacive (martensite-type) transformation in Pt3Al. In the alloys with low ruthenium contents, ruthenium was found to be partitioned almost exclusively

Arc-melted Al-rich samples from the Al–Cr–Ni system were analysed using optical microscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy and X-ray diffraction. All of the expected binary phases were observed and identified.

The Al–Ir–Ru phase diagram was investigated using optical and scanning electron microscopy, energy dispersive X-ray analysis and X-ray diffraction. The results were self-consistent but there was little published literature available for compariso

Data collection for the calculation of phase equilibria is discussed, with reference to the Al‒Ni‒Re system. Since there were conflicting data for the Al‒Re system and no data at all for the ternary system, an extensive experimental programme w

The Al–Ir phase diagram was investigated using optical and scanning electron microscopy, and X-ray diffraction. The results were found to agree with published literature, with the exception of the congruent melting of Al2.7Ir and a previously unrep

An investigation was undertaken to ascertain the extension of the B2 phase fields from AlNi and AlRu in the Al–Ni–Ru ternary system. The samples were arc-melted, annealed at 1500 or 1600 °C, and examined using optical microscopy, scanning electr
