Download or read book Investigation of Welding and Brazing of Molybdenum and Tzm Alloy Tubes written by National Aeronautics and Space Adm Nasa and published by . This book was released on 2018-10-20 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This effort involved investigating the welding and brazing techniques of molybdenum tubes to be used as cartridges in the crystal growth cartridge. Information is given in the form of charts and photomicrographs. It was found that the recrystallization temperature of molybdenum can be increased by alloying it with 0.5 percent titanium and 0.1 percent zirconium. Recrystallization temperatures for this alloy, known as TZM, become significant around 2500 F. A series of microhardness tests were run on samples of virgin and heat soaked TZM. The test results are given in tabular form. It was concluded that powder metallurgy TZM may be an acceptable cartridge material. Lundblad, Wayne E. Unspecified Center NASA ORDER H-080640...

This book was released on 2012-04 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific and technological challenges associated with the processing of molybdenum and TZM (Mo-0.6Ti-0.2Zr-0.02C) alloy was investigated. The broad objective was to study the (i) kinetics of hydrogen reduction of MoO3 to Mo and morphology of reduced Mo powder, (ii) mechanical alloying and hot isostatic pressing for the preparation of TZM alloy, (iii) densification and grain growth behavior during sintering of Mo and TZM compacts, (iv) fabrication of TZM alloy tube using powder metallurgy route, (v) hot deformation behavior of TZM alloy in 600-900 C, and (vi) development of silicide and alumino-silicide based oxidation resistant coatings on TZM alloy. The experimental procedures and the outcome or results reported in this work would provide a significant basis for the future developmental work on high temperature materials suitable for construction of high temperature power generating reactors.

Available in PDF, EPUB and Kindle. Book excerpt: Brazed molybdenum and tantalum alloy honeycomb structures offer good potential for structural and heat shield applications in the 2500 - 3500F range. However, molybdenum is seriously embrittled at braze temperatures above approximately 2500F. Tantalum alloys are not embrittled by high braze temperatures, but there are serious production problems associated with braze temperatures above 3000F. The purpose of this program is to develop molybdenum and tantalum braze systems which braze at relatively low temperatures, but develop high remelt temperatures. Some attention is also being directed to the development of braze alloys for tantalum that braze several hundred degrees above the expected service temperature. Most of the effort will be based on the TZM molybdenum alloy and the Ta-10W alloy. Some work will be performed using the Ta-8W-2Hf and Ta-30Cb-7,5V alloys. (Author).
