Shows the changes on polished and on polished and etched surfaces of globular grey cast iron (GGG-50) under tensile stress. A specially developed sample, with large radius and two opposite notches, is...
Shows the intermediate-state structures of an evaporated superconducting lead film of 7mm thickness in a vertically applied magnetic field of variable amplitude. The domains have been made visible by means...
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...
By means of the magneto-optic Kerr effect, WEISS domains (tiny crystal parts) can be made visible and their changes followed as a magnetic field is set up. Simple magnetic reversal processes, caused by the...
Shows the development of the martensite from the super-cooled austenite in the needle profile, formed by the sudden change of volume, of a polished surface of a chrome-nickel steel under the heating table...
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...
