ABSTRACTThe basic physical properties and steps in the manufacture of zirconium and important zirconium based materials are discussed. Once considered prohibitively expensive for structural use, its current cost is becoming competitive with other special alloys for various industrial applications. Its actual life cycle cost in many cases has been considerably lower than that experienced with alternative materialsPhysical properties which combine to make zirconium attractive include: high strength, particularly when alloyed, outstanding resistance to many forms of corrosion in marine, industrial and most other environments, superior fatigue resistance and good metallurgical workability. Its oxide compound, zirconia, has become a base material for a new generation of tough ceramics. These ceramics are also candidates for fiber reinforcement. Several modern ceramic fabrication techniques are discussedThis review is a compilation of data and information from various sources concerning the physical properties, manufacture, and availability of zirconium and zirconium based materials. It is not intended as an exhaustive analysis of the subject. Rather, it should serve as a convenient introduction for those interested in this group of increasingly attractive alternative structural materials. |
