Book Fretting of Nickel chromium aluminum Alloys at Temperatures to 816 C

Download or read book Fretting of Nickel chromium aluminum Alloys at Temperatures to 816 C written by Robert C. Bill and published by . This book was released on 1974 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of four nickel-based alloys containing 10 percent and 20 percent chromium in combination with 2 percent and 5 percent aluminum were fretted in dry air at temperatures to 816 C. At all temperatures, the alloys showed far less fretting wear than did high-purity nickel. This was attributed to the formation of protective oxide films on the alloys, the result of the selective oxidation of the alloy constituents. Increasing the aluminum concentration reduced fretting wear at all temperatures. Increasing the chromium concentration from 10 percent to 20 percent resulted in decreased fretting wear at 23 and 540 C, but increased fretting wear at 650 and 816 C.

Book Woldman s Engineering Alloys

Download or read book Woldman s Engineering Alloys written by John P. Frick and published by ASM International. This book was released on 2000-01-01 with total page 1369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation New edition of a reference that presents the values of properties typical for the most common alloy processing conditions, thus providing a starting point in the search for a suitable material that will allow, with proper use, all the necessary design limitations to be met (strength, toughness, corrosion resistance and electronic properties, etc.) The data is arranged alphabetically and contains information on the manufacturer, the properties of the alloy, and in some cases its use. The volume includes 32 tables that present such information as densities, chemical elements and symbols, physical constants, conversion factors, specification requirements, and compositions of various alloys and metals. Also contains a section on manufacturer listings with contact information. Edited by Frick, a professional engineering consultant. Annotation c. Book News, Inc., Portland, OR (booknews.com).

Book Evaluation of the Corrosion Resistance of Iron aluminum chromium Alloys in Simulated Low Nitrogen Oxide Environments

Download or read book Evaluation of the Corrosion Resistance of Iron aluminum chromium Alloys in Simulated Low Nitrogen Oxide Environments written by Ryan M. Deacon and published by . This book was released on 2007 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: STEM analysis of the as-corroded coupons revealed that chromium was able to form chromium sulfides only on the higher aluminum alloy, thereby preventing the formation of deleterious iron sulfides. When the aluminum concentration was too low to permit selective oxidation of only aluminum (upon initial exposure to the corrosion environment), the formation of chromium oxide alongside the aluminum 1 oxide led to depletion of chromium beneath the oxide layer. Upon penetration of sulfur through the oxide into this depletion layer, iron sulfides (rather than chromium sulfides) were found to form on the low aluminum alloy. Thus, it was found in this work that the role of chromium on alloy corrosion resistance was strongly effected by the aluminum concentration of the alloy. STEM analysis also revealed the encapsulation of external iron sulfide products with a thin layer of aluminum oxide, which may provide a secondary layer of a corrosion protection in these regions.

Book Copper Distributions in Aluminum Alloys

Download or read book Copper Distributions in Aluminum Alloys written by Timothy Harvey Muster and published by . This book was released on 2009 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminium alloys are used extensively throughout the world, in items such as decorative architectural applications through fasteners to high strength structural applications. Such a diverse range of application areas has a similarly diverse range of requirements for materials properties and performance. The mechanical properties are achieved through alloying aluminium with a wide range of elements. Copper, which is one of the major alloying additions, is added in varying amounts to many of the different aluminium alloy series, with the lowest levels in the purest wrought aluminium alloys (AA1xxx series) and the highest levels in the high strength AA2xxx series. The distribution of copper in aluminium alloys varies from copper atoms dispersed in solid solution through the formation of clusters of copper atoms and then onto to a range of intermetallic compositions and particle sizes. The presence of copper in all these forms, particularly in the AA2xxx series, has a significant impact on the chemistry and electrochemistry of the surface of the alloy and, hence, on the susceptibility to corrosion and approaches to metal finishing. This book examines how the copper distributions change, as a result of corrosion reactions, and explores the influence of these changes on continued corrosion. The influence of the distribution of copper in aluminium alloys on metal finishing processes and the redistribution of copper as a result of metal finishing are also examined.

Book Thermophysical Properties of Thermal Energy Storage Materials Aluminum

Download or read book Thermophysical Properties of Thermal Energy Storage Materials Aluminum written by Clare C. Leiby and published by . This book was released on 1973 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to RN-AFAPL-08-72-8, a program was initiated to determine the compatibility of Inconel canisters with specific thermal energy storage materials. A uniform temperature vacuum oven and and a 100-min (65 min on and 35 min off) oven control were designed and constructed. The timer-oven system generates the thermal cycle of an energy storage canister in near-earth orbit. An X-750 alloy canister was fabricated, precipitation-hardened, loaded with 215 gm of pure aluminum, and sealed off under high vacuum. It was then fitted with six thermocouples and placed in the oven for a 5000-hr test. Initial temperature measurements indicated that the aluminum alternately melted and froze during each temperature cycle. After 48 hr, only partial melting occurred. After 9 days of continuous cycling, all melting had ceased and the test was terminated. It was found that the canister had ruptured and that its contents were extremely hard. Electron microprobe analysis revealed the contents to be an aluminum-nickel-chromium-iron alloy with a density of 3.2 gm/cc (vs 2.7 gm/cc for pure aluminum). It is evident that the canister material was dissolved by the molten aluminum and that the coefficient of thermal expansion of the resulting alloy was large enough to cause the canister to rupture explosively. Preparations are under way for similar tests using eutectic mixtures of alkali fluorides. (Author).
