Polymorphic transformations complicate the mechanical properties and their temperature dependence in cerium. The 0.2% offset yield strength data from Owen and Scott (1976) shown in fig. 8.18 reveal the effect of the y(f.c.c.) to /3(d.h.c.p.) transformation beginning at about 280 K. The yield stress tends to increase with increased amount of p phase as the temperature decreases. At approximately 110 K the yield strength rises dramatically in association with the transformation of the remaining y(f.c.c., a = 5.16) to a(f.c.c., a = 4.85), see ch. 4 section 2.4.5. With decreasing temperature the ultimate tensile strength rises rapidly at about 375 K. This rise probably reflects deformation-induced 7 to J3... 

Carbon-based materials with a large surface area, suitable porosity, and low electronic resistance are usually used as 3D electrode materials for RFBs, including zinc/ bromine, all-vanadium, bromine-polysulfide, and zinc-cerium RFBs [4]. These carbon-based materials are made of polymer binders and conductive particles and include polymer-impregnated graphite plates, conductive carbon-polymer composites, and polymer-impregnated flexible graphite, which are low-cost and lightweight and have better mechanical properties. 

As described abo o, structural modification is produced in the systems aluminiun -silicon and iron-carbon by the addition of sodium and magnesiarn or cerium, respectively. After modification the structure of Fig- 5.6 appears as shown in Fig. 5.9. Two points should be noted (i] the modified structure has significantly improved mechanical properties, especially toughness, and (ii) the growth process is affected in such a way that primary dendritic growth occurs in what is noniinally an alloy of eutectic composition. These... 

Cerium(lV) compounds with suitable reducing agents, readily initiate the redox polymerization of, for example, vinyl monomers [22]. This property is used to initiate graft polymerization of vinyl monomers onto cellulose, wool, starch, cotton, etc. in order to, e.g. improve mechanical strength, resist moisture penetration and reduce micro-organism attack.
