15、um on Refractory Metals and Their Industrial Applications,held on 23-24 September 1982 in New Orleans,Louisiana,was sponsored by ASTM Committee B-10 on Reactive and Refractory Metals and Alloys.Al-though Committee B-10 has for some time written standards used for com-mercial applications of refracto
16、ry metals and has sponsored previous sympo-sia on reactive metals,this conference was its first devoted to the refractory metals(molybdenum,niobium,tantalum,and tungsten).It was energetically supported by suppliers and fabricators and was intended to provide a com-prehensive description of these four metals for the industrial user.Indeed,the symposium was conceived and based on the premise that no publication exists for the industrial user on the various properties and end uses of these metals.W
