Book Description
The program was carried out for the development of a fabricable columbium-base alloy with improved oxidation resistance and good strength-properties at 2000F and above for use as a blade material in gas turbine engines. Nineteen electron beam melted ternary alloys from the Cb-W-Ta and Cb-W-Hf systems within the composition range 10-25 percent tungsten, 15-30 percent tantalum, 2-35 percent hafnium, were evaluated for fabricability, tensile and creep-rupture strength properties, and oxidation resistance.

Book Description
As part of a project to develop refractory metal alloys suitable for high-temperature structural applications, the Bureau of Mines applied solid solution and precipitation-hardening techniques to columbium and tantalum alloys. Thirty three alloys were evaluated to determine their formability, strength, and oxdation resistance.

Book Description
Research and development in the field of high-strength stainless steels appears to be directed along two principal paths: (1) the development of alloys with improved strength properties and (2) the accumulation of information on the properties and physical metallurgy of existing alloys so that they may be used more effectively. By and large, the development of new alloys is being carried out by the stainless-steel producers, while the accumulation of property data for the most part is being undertaken on Government contracts.

Author: H. E. Pattee Publisher: ISBN: Category : Brazing Languages : en Pages : 28
Book Description
Many of the important developments in the joining of columbium, molybdenum, tantalum, tungsten, and graphite are summarized. Much of the subject matter is devoted to the brazing processes, but diffusion and solid-state bonding are covered also. The particular properties which recommend the refractory metals and graphite to aerospace applications are discussed. Adverse properties which limit the use of these materials or which must be overcome by using special precautions also are mentioned. Typical filler metals used to join the refractory materials for low- as well as high-temperature service conditions are covered. The information was gathered from the current literature on joining and from the open DMIC files.
