Download or read book Effect of Overheating on Creep-rupture Properties of S-816 Alloy at 1,500 Degrees F written by John P. Rowe and published by . This book was released on 1957 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of overheats to temperatures of 1650, 1800, 1900, and 2000 F were evaluated in terms of the changes in creep-rupture characteristics at 1500 F of S-816 alloy under stresses within the range of rupture strengths of the alloy for 100 to 1000 hours. Overheat periods were predominantly of 2-minute duration and were applied cyclically at approximately 5- or 12-hour intervals. The possible damage from overheating was believed to include internal metal structure changes induced by exposure to the higher temperatures and loss of life by creep if stress was present during the overheats.

This book was released on 1957 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of overheating HS-31 alloy to temperatures of 1,650 degrees, 1,800 degrees, 1,900 degrees, and 2,000 degrees F during the course of rupture tests 1,500 degrees F was carried out. The overheating was applied periodically for 2 minutes in most of the tests. The intent was to develop basic information on the effect of overheats on creep- rapture properties in order to assist in the evaluation of damage from overheats during gas- turbine operation.

Available in PDF, EPUB and Kindle. Book excerpt: A study was carried out of the influence of periodic overheats of 2-minute duration to temperatures of 1,650, 1,800, 1,900, and 2,000 degrees F on the creep-rupture properties of M-252 alloy at 1,500 degrees F. The conditions of the experiments had been selected to provide basic information applicable to estimation of the effects of overheating on creep-rupture performance of gas-turbine parts. The overheats were conducted both with the stress removed during overheating and with stress present.
Book Synopsis Creep, Rupture, and Notch Sensitivity Properties of S-816 Alloy Up To 1650 F Under Fatigue and Static Stress by : F. Vitovec
Download or read book Creep, Rupture, and Notch Sensitivity Properties of S-816 Alloy Up To 1650 F Under Fatigue and Static Stress written by F. Vitovec and published by . This book was released on 1956 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue, rupture, and creep data obtained under various combinations of mean and alternating stress are presented for S-816 alloy at temperatures of 75, 1350, 1500, and 1650 F. Tests were performed under axial stress on unnotched specimens and specimens having theoretical stress concentration factors of 2.4 and 3.4. The data are presented as S-N curves and stress range diagrams to show the effect of specimen notch, temperature, ratio of alternating-to-mean stress, and stress magnitude on the fatigue and creep properties. The role of both creep and fatigue as design factors and the relation of notch sensitivity to loading conditions are discussed with particular reference to temperature and ratio of alternating-to-mean stress.

Book Synopsis Effect of Heat Treatment at 1150 C on Creep-rupture Properties of Alloy FA-180 by :
Download or read book Effect of Heat Treatment at 1150 C on Creep-rupture Properties of Alloy FA-180 written by and published by . This book was released on 1996 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alloy FA-180, with a composition of Fe-28Al-5Cr-0.5Nb-0.8Mo-0.025Zr-0.05C-0.005B (at.%), is of interest because of its improved creep-rupture resistance when compared to alloy FA-129 (Fe-28Al-5Cr-0.5Nb-0.2C). At a temperature of 593 C and under a stress of 207 MPa, the creep-rupture life of FA-129 heat treated for 1 h at 750 C is about 20 h while the FA-180 alloy lasts approximately 100 h. Heat treatment at 1,150 C has been shown to further improve the creep life of FA-180 and creep-rupture lives of approximately 2,000 h have been attained. This strengthening was attributed to the presence of fine matrix and grain boundary Zr-rich MC precipitates that were produced by the heat treatment. The current study continues the investigation of the effect of heat treatment at 1,150 C on the improvement of creep-rupture life in alloy FA-180. As part of the effort to understand the strengthening mechanisms involved with heat treatment at 1,150 C, transmission electron microscopy was used to correlate the microstructure with the improved creep resistance. Results indicate that heat treatment at 1,150 C for 1 h, followed by rapid quenching in water or mineral oil, produces even further improvements in the creep-rupture life of this alloy. A specimen being tested at 593 C and 207 MPa was stopped after over 6000 h of life, while another specimen lasted over 1,600 h at 650 C and 241 MPa. The microstructure of the oil-quenched specimen contained many dislocation loops which were not present in the air-cooled specimens. These loops pinned dislocations during creep testing at temperatures of 593--700 C, resulting in stabilized deformation microstructure and increased creep-rupture strength.
