Describes the changes that take place on the surface of extra-mild steel kept in a gaseous atmosphere of uranium hexafluoride. Illustrates the formation and thickening of interferential film; preferential...
For this production specimens of up to 8% pre-deformation of an aluminium-1%-magnesium alloy have been investigated in a transmission electron microscope using an acceleration voltage of 100 kV. The...
Shows the changes on a polished and etched surface of deep-drawing St VII 23 sheet metal under tensile stress. The stretch behaviour up to breaking-point in the elastic and plastic domain is shown. The...
Shows processes used in the refining of platinum, palladium, rhodium, ruthenium, iridium, gold and silver concentrates remaining after nickel and copper are extracted from the ore.
Detailed description of the refining of copper from the relatively crude 97% pure blister copper to the electrolytically refined copper of 99.97% purity.
Explains the purpose of refining and shows some of the principles involved. Surveys electrolytic and Mond Carbonyl methods of nickel refining on the large scale necessary to obtain the great quantities of...
Sir Lawrence Bragg uses bubbles on the surface of a liquid to illustrate phenomena such as grain boundaries, elastic and plastic deformation, dislocations and their interaction, the effects of impurities and...
An introduction to the problems of corrosive attack with an explanation of its underlying causes. In 3 sections: 1) The nature of corrosion - anode and cathode processes (20 min); 2) Origins and...
