The detailed annealing behaviour of large faulted dislocation loops in aluminium and aluminium-base alloys has been studied by quantitative electron microscopy. Changes in loop shrinkage rates, loop character and dislocation pinning have been observe

(...) Shoot dry matter production for the initial 144-d growth period and two subsequent 22-d regrowths was significantly higher for the 450 kg P ha −1 rate at all temperatures; however, yield increase resulting from an increase in S was minimal (<

We have studied the growth of the silver sulfide tarnish film which forms on silver deposited on smooth, amorphous substrates and rough and smooth polycrystalline substrates. Both ellipsometric and electron‐microscope techniques were used to measur

The structural relationship between the different planar secondary defects which are observed in Al and Al-based binary alloys has been considered and additional observations made to show that the changes in structure which occur in the alloy systems

Ellipsometry was used to determine growth rates for the Ag 2 S corrosion film which forms on silver in room air. This system is a particularly unfavorable one for an ellipsometric investigation since the Ag 2 S is strongly absorbing and grows as a di
