Small amounts of nickel are added to titanium to improve the crevice corrosion resistance but this results in an alloy which has sheet fabrication difficulties and is subject to the formation of large Ti2Ni precipitates. These large precipitates can serve as local corrosion sites; but in a smaller more widely dispersed form, they can have a beneficial effect on crevice corrosion resistance. The purpose of the present work is to show that the addition of a small amount of Mo to the Ti-1.5Ni alloy reduces the Ti2Ni precipitate size and produces a more elongated grained microstructure. It has recently been reported that small additions of Mo to Ti-0.8 to lw/o Ni alloys produce good crevice corrosion resistance and improved fabrication properties.

Gold thin film metallizations in microelectronic circuits have a distinct advantage over those consisting of aluminum because they are less susceptible to electromigration. When electromigration is no longer the principal failure mechanism, other failure mechanisms caused by d.c. stressing might become important. In gold thin-film metallizations, grain boundary grooving is the principal failure mechanism.Previous studies have shown that grain boundary grooving in gold films can be prevented by an indium underlay between the substrate and gold. The beneficial effect of the In/Au composite film is mainly due to roughening of the surface of the gold films, redistribution of indium on the gold films and formation of In2O3 on the free surface and along the grain boundaries of the gold films during air annealing.

In conjunction with the current “revisionism” of English history from a Catholic viewpoint, it is time to undertake a corresponding revision of the plays and personality of William Shakespeare. For this purpose it is not enough to rest content with the meagre historical record, but we have to go ahead in the light of recusant history with a reinterpretation of the plays, considering the extent to which they lend themselves to the Catholic viewpoint. This is not merely a matter of nostalgia for the mediaeval past, but it looks above all to the present sufferings of the “disinherited” English Catholics — in the light of the continued presence of Christ who is suffering, as Pascal famously noted, in his faithful even till the end of the world.
