High-pressure Research

Bridgman had strong views on the importance of empirical research, influenced as little as possible by theory, and this helped him test the influence of numerous variables that lesser mortals failed to heed. He kept clear of quantum mechanics and dislocation theory, for instance. He became deeply ensconced in the philosophy of physics research for instance, he published a famous book on dimensional analysis, and another on the logic of modern physics . When he sought to extrapolate his ideas into the domain of social science, he found himself embroiled in harsh disputes this has happened to a number of eminent scientists, for instance, J.D. Bernal. Walter s book goes into this aspect of Bridgman s life in detail. 

It appears that HIP was independently invented, also in 1955, at the Battelle Memorial Institute in Columbus, Ohio, under contract to the Atomic Energy Commission and with the immediate objective of bonding nucelar fuel elements with precise dimensional control. 

The various densification mechanisms at different temperatures can be modelled and displayed in HIP diagrams, in which relative temperature is plotted against temperature normalised with respect to the melting-point (Arzt el al. 1983). This procedure relates closely to the deformation-mechanism maps discussed in Section 5.1.2.2. 

Robert Hazen s excellent 1999 book on the diamond-makers has been repeatedly cited. Earlier, he had brought out a popular account of high-pressure research 

The high-pressure community is now drawn from many fields of interest and many branches of expertise. A recent symposium report (Wentzcovich el al. 1998)

New metliods appear regularly. The principal challenges to the ingenuity of the spectroscopist are availability of appropriate radiation sources, absorption or distortion of the radiation by the windows and other components of the high-pressure cells, and small samples. Lasers and synchrotron radiation sources are especially valuable, and use of beryllium gaskets for diamond-anvil cells will open new applications. Impulse-stimulated Brillouin [75], coherent anti-Stokes Raman [76, 77], picosecond kinetics of shocked materials [78], visible circular and x-ray magnetic circular dicliroism [79, 80] and x-ray emission [72] are but a few recent spectroscopic developments in static and dynamic high-pressure research.

Reluctantly, in 1929 Ipatieff left his homeland for the United States. He remained at UOP for the remainder of his life. Northwestern University, which had close ties to UOP, appointed Ipatieff to a professorship and directorship of the university s high-pressure research laboratory.
