what is known as 'Arabian Medicine"' (p. VII). Recent research, however, shows more and more that one cannot speak of a medieval Jewish medicine proper. Jewish physicians studied the Arabic medical works which are based on the Galenic medical tradition. A good example is Maimonides, who according to Jewish scholars, made such a great contribution to medieval medicine. But it now clear that he w...

CASTABILITY OF Al-Li-Mg AND Al-Li-Cu-Mg ALLOYS

The objective of the present work is to study the casting characteristics of various A1-Li alloys, which include fluidity and strengths of the alloys and their interaction with cast molds. Materials investigated are Al-Li-Mg and Al-Li-Cu-Mg alloys with Li content of 2.5 wt%. The results show that sand molds with resin binders are good for A1-Li casting. Ceramic coatings can further reduce the m...

Zener Relaxation in Al-Li Binary Alloys

Internal friction (I.F.) and modulus measurements have been carried out as a function of temperature in order to study the Li mobility in an A1 8.1 at% Li 0.03 at% Zr alloy. The results show that the sequence of 6' and 6 precipitation can be followed through the evolution of the internal friction spectra. Two peaks appear in the internal friction spectrum. The low temperature peak Pz (450 K), h...

DECOMPOSITION IN BINARY Al-Li ALLOYS

We have investigated the influence of aging on the morphology and phase composition of annealed Al-Li binary alloys by means of an atom probe with a multi-detection system. The influence of artifacts such as the preferential evaporation of the Li-atoms and the pile-up effects for the Al-atoms were analysed as well. Specimens of Al 2.0 wt%Li andAl -2.9 wt%Li were solution treated and aged at 190...
