Titanium aluminide intermetallics have received much attention for potential application in areas of aerospace, automobile and marine due to their relatively high strength, low density and high resistance to oxidation. They are likely to be exposed to a variety of corrosive environments. Therefore, knowledge of their corrosion behaviour is necessary for potential applications. The present work investigates the microstructure and corrosion behaviour of a number of titanium aluminides with salt-fog spray and methods of electrochemical polarisation. The mechanism of salt fog corrosion of...

With a documented history stretching back a thousand years, Dunster Castle on the Somerset coast is one of Britain's oldest and most intriguing great buildings, its turrets evoking centuries of siege warfare, dark deeds, bloodshed and treachery. Dunster's rich and colourful story covers more than nine hundred years of intermittent warfare. Only two families have owned and occupied the castle, from the Norman Conquest in 1066 which led to its construction right through to the 20th century; the second of these remained in charge for 21 generations and six hundred years. These families and their...

With a documented history stretching back a thousand years, Dunster Castle in Somerset is one of Britain's oldest and most intriguing great buildings, its turrets evoking centuries of warfare, dark deeds, bloodshed and treachery. What makes it particularly unusual is the prominent role women have played in its fortunes, from the indomitable Joan de Mohun in the 14th century, who promised as much land to the villagers as she could walk around barefoot in a day, to Lady Jane Luttrell, who saw off a Royalist attack during the English Civil War by personally commanding the cannons. Jim Lee worked...
