Book Low Cycle Fatigue of Ti 6Al 4V at 423 F

Download or read book Low Cycle Fatigue of Ti 6Al 4V at 423 F written by R. R. Hilsen and published by . This book was released on 1963 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the effects of various factors on low-cycle fatigue phenomena in connection with space vehicle design, axial tension fatigue tests up to 2000 cycles were conducted on titanium alloy, Ti-6Al-4V, at -423 F. The effects of changing the minimum-to-maximum load ratio and cycling speed for the range tested were slight. The fatigue strength of pressure-welded specimens was within 1 per cent of that of the base metal. Fatigue strengths at -423 F were 65 to 68 per cent higher than those at room temperature.

Book Influence of Heat Treatment on the Fatigue Lives of Ti 6Al 4V and Ti 4 5Al 5Mo 1 5Cr

Download or read book Influence of Heat Treatment on the Fatigue Lives of Ti 6Al 4V and Ti 4 5Al 5Mo 1 5Cr written by AC. Fraker and published by . This book was released on 1983 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports on the effects of heat treating on phase composition and fatigue behavior of the Ti-6Al-4V and the Ti-4.5Al-5Mo-1.5Cr alloys. Corrosion-fatigue experiments show that the Ti-6Al-4V alloy has the longest fatigue life when heat treated at 900°C and quenched. The Ti-4.5Al-5Mo-1.5Cr alloy has an increased fatigue life under higher strain when heat treated at higher temperatures in the ?-? region. Comparison of the fatigue lives of the Ti-6Al-4V and Ti-4.5Al-5Mo-1.5Cr alloys in the mill-annealed condition shows that Ti-4.5Al-5Mo-1.5Cr has improved fatigue behavior in the high-cycle region, but Ti-6Al-4V is superior in the low-cycle region.

Book Load Interaction Effects on Fatigue Crack Growth in Ti 6Al 4V Alloy

Download or read book Load Interaction Effects on Fatigue Crack Growth in Ti 6Al 4V Alloy written by Robert Peh-ying Wei and published by . This book was released on 1973 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of delay, retardation in the rate of fatigue crack growth, produced by load interactions in variable amplitude loading, on the accurate prediction of fatigue lives of engineering structures is discussed. The effects of a broad range of loading variables on delay in fatigue crack growth at room temperature are examined for a mill annealed Ti-6Al-4V alloy. The results are used to estimate crack growth behavior under programmed loads.

Book Behavior of Materials Under Conditions of Thermal Stress

Download or read book Behavior of Materials Under Conditions of Thermal Stress written by S. S. Manson and published by . This book was released on 1953 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review is presented of available information on the behavior of brittle and ductile materials under conditions of thermal stress and thermal shock. For brittle materials, a simple formula relating physical properties to thermal-shock resistance are derived and used to determine the relative significance of two indices currently in use for rating materials. The importance of simulating operating conditions in thermal-shock testing is deduced from the formula and is experimentally illustrated by showing that BeO could be both inferior or superior to Al2O3 in thermal shock depending on the testing conditions. For ductile materials, thermal-shock resistance depends upon the complex interrelation among several metallurgical variables which seriously affect strength and ductility. These variables are briefly discussed and illustrated from literature sources. The importance of simulating operating conditions in tests for rating ductile materials is especially to be emphasized because of the importance of testing conditions in metallurgy. A number of practical methods that have been used to minimize the deleterious effects of thermal stress and thermal shock are outlined.

Book Influences of Chemical and Thermal Environments on Delay in a Ti 6Al 4V Alloy

Download or read book Influences of Chemical and Thermal Environments on Delay in a Ti 6Al 4V Alloy written by TT. Shih and published by . This book was released on 1976 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influences of chemical and thermal environments on delay in fatigue crack growth under elemental load spectra were examined for a mill-annealed Ti-6Al-4V alloy. The results indicate that delay is significantly affected by the hold time at high load in 3.5 percent NaCl solution at room temperature, and by both temperature and thermal history. In 3.5 percent NaCl solution, delay may be increased by 40 times through increasing the hold time from zero to 900 s, the specific amount depends on the overload ratio (Khmax/Klmax) and the maximum value of the low-amplitude fatigue load (or Klmax. Delay is generally higher at the higher test temperature (560°F or 293°C), although the trend in behavior associated with changes in loading variables is similar to that observed at room temperature. Delay is significantly increased when the high load is applied at a high temperature, with subsequent fatigue at room temperature. It is reduced by intermediate heating at a high temperature following a high-load excursion at room temperature, and is lowest when fatigue loads are applied at high temperature following a high-load excursion at room temperature. The significance of these results in terms of modeling and life prediction procedures is discussed.
