A Survey of Alloy-Eutectic Sources for Aligned Structures

摘要

A nearly complete evaluation of known binary alloy eutectic systems has been made with the exceptions of incomplete listing of Rare Earth Metals and of Refractory Metals. Seventy-seven eutectic systems are listed as unfavorable for production of useful whisker (or aligned) structures. Twenty-eight binary eutectic systems are listed as being possible sources for beneficially aligned structures. Some limitations are discussed. The relative value of using high pressure to increase yield quantities is indicated for specific systems. The high cost for high pressure yields does not appear warranted in any case, (at least for sometime to come). (Author)
