The elastic moduli vs. temperature curves of the hypoeutectic Ti-Si7.5-All alloy and of the directionally solidified eutectic a-Ti-Ti5Si3 composite with discontinuous Ti5Si3 fibers -aspect ratio of lf/df 50- are depicted in fig. 14. In comparison the temperature-dependent Young s modulus of the polycrystalline Ti5Si3 compound is also shown in the diagram. A detailed description and discussion of the elastic moduli of the pure silicides is given in section 4.3. 

Young s Modulus. Young s moduli, E, for several resins are plotted vs. temperature in Fig. 7. Young s moduli were determined from stress-strain diagrams. At 4K, their values are within 10%. Therefore, the low-temperature values of E do not depend markedly on the detailed chemical structure. It must be emphasized that epoxy resins are energy-elastic and have a nearly linear stress-strain behavior to fracture at low temperatures. No rate dependence was found over several decades. This is not true for many high polymers, such as polyethylene (PE), which are not cross-linked. PE behaves viscoelastically, even at 4 K [%...

Shear modulus data obtained as a function of temperature were converted to Young s modulus equivalents through E = 3G. Values of 3G(10) vs temperature are shown in Figures 6-10. 

The superior cold properties of lithium polymers were even more pronounced in the case of butadiene-styrene copolymers than in the poly butadienes. As Figure 2 shows, a butadiene-styrene copolymer (33% styrene) prepared with lithium outperformed LTP (23.5% styrene, emulsion recipe, 5°C.) by 21 °C. in regard to the temperature at which Young s bending modulus reaches 10,000 pounds per square inch. The fact that the lithium polymer had a higher styrene content and also a higher Mooney viscosity (130 vs. 49) than LTP should have affected its cold properties adversely therefore, the superior performance of the lithium copolymer is significant.
