Handbuch der Metallphysik Distortion of Metal Crystals

Abstract

The investigation of metals by physical methods has undergone a remarkable development during the last fifteen years. To this progress both physicists and metallurgists have contributed. On one hand, metals and alloys can now be examined over a much larger range of temperature and pressure, and in much stronger magnetic fields than was previously the case. The application of methods of X-ray analysis enables the lattice structure to be ascertained in which the positions of the atoms and the distances between them can be experimentally determined. It is now possible, in the case of any solid alloy, to determine not only the number of phases at any given composition, but also the distribution of the atoms in those phases. For this reason, the microscope and the X-ray spectrometer have become twin instruments for the characterisation of the structure of any metal or alloy. During the period in question, theoretical physicists have been paying increased attention to the problems of the metallic state. On the other hand, the new technique, devised by metallurgists for the production of single crystals of metals by a variety of methods, has placed in the hands of physicists the most perfect form of any metal for investigation. In addition, the progress of metallurgical research has rendered available a far larger number of metals in sufficient quantities for investigation than was previously the case. Add to this the fact that the majority of metals are now available in a state of purity which exceeds 999 parts per thousand, and it will be seen that all the conditions are present for an intensive investigation of them by the best methods of physical research.
