Book Synopsis Temper Embrittlement in a Thick-Wall Gun Tube Steel by : Richard S. DeFries
Download or read book Temper Embrittlement in a Thick-Wall Gun Tube Steel written by Richard S. DeFries and published by . This book was released on 1972 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was undertaken to determine the reversibility and susceptibility to temper embrittlement in large 3Ni-Cr-Mo alloy gun tube forgings. The effect of time at temperature in the temper-brittle range was determined. In addition, the effect of microstructure on temper embrittlement was also studied. The degree of embrittlement was based on the change in the fracture appearance transition temperature. It was found that the transformation causing embrittlement is a reversible reaction and that tempering a martensitic structure above 1000F produced no embrittlement. Retempering at a lower temperature can cause embrittlement without a significant change in the yield strength or Charpy impact energy. In tempered martensite, the ductile brittle transition appears to be a function of the yield strength. (Author).

Book Synopsis Temper Embrittlement in High Purity 3.5Ni, 1.75Cr, 0.20C Steel by : G. C. Gould

Available in PDF, EPUB and Kindle. Book excerpt: A number of trace elements and some intentional steelmaking additions are known to contribute to the temper embrittlement of susceptible steels. Most of the work done to date has been on individual elements in tempered martensitic steels. This work is concerned with steels in a tempered bainitic condition whose heat treatment and final structure simulate closely that of a large forging, and is designed to study some solute element interactions that were thought to exist. The effects of manganese and molybdenum on embrittlement by phosphorus are investigated as well as that of manganese in combination with silicon. A series of 18 heats of 3.5 nickel, 1.75 chromium, 0.20 carbon steel were made by vacuum-induction melting using high purity components. The levels of phosphorus, manganese, silicon, and molybdenum were varied to measure their influence on temper embrittlement. Embrittlement was measured as a shift in the transition temperature determined from the conventional V-notch Charpy impact tests. Both a step-cooling heat treatment and isothermal exposures at 750, 850, and 950 F were used as embrittling treatments. Isothermal exposures were run to 3500 h with embrittlement measured at 100, 1000, and 3500-h exposure. It was found that manganese contributes to temper embrittlement and magnifies or interacts with the effect of phosphorus. Molybdenum varying between 0.2 and 0.84 per cent is demonstrated to curtail embrittlement by phosphorus and not contribute to temper embrittlement itself. Silicon alone or with manganese is shown to contribute to temper embrittlement both during isothermal exposures and slow cooling through the critical temperature range. Limits on solutes may be placed so that a Ni-Cr-Mo-V steel will show no significant temper embrittlement during slow cooling or subsequent isothermal exposure.

Book Synopsis A Study of Temper Embrittlement During Stress Relieving of 5Ni-Cr-Mo-V Steels by : L. F. Porter
Download or read book A Study of Temper Embrittlement During Stress Relieving of 5Ni-Cr-Mo-V Steels written by L. F. Porter and published by . This book was released on 1968 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive studies of the effect of alloying elements and residual elements on the susceptibility of Ni-Cr-Mo-V steels to temper embrittlement have led to the selection and evaluation of a preferred composition for a weldable quenched and tempered plate steel that is resistant to temper embrittlement during stress relieving. The embrittling effects of carbon, manganese, nickel, chromium, and molybdenum were determined in a statistically selected series of 27 composition modifications of a 5Ni-Cr-Mo-V steel. In addition, the effects of vanadium contents up to 0.19 per cent were investigated. The results of these studies showed that manganese and molybdenum were alloying elements primarily responsible for temper embrittlement in the steel. The effect of the residual elements phosphorus, aluminum, nitrogen, and oxygen on the susceptibility of 5Ni-Cr-Mo-V steel to temper embrittlement was determined. This study showed that although oxygen was detrimental to the notch toughness of the steels, only phosphorus contributed to temper embrittlement. On the basis of the preceding studies, a quenched and tempered plate steel with minimum susceptibility to temper embrittlement was selected; this composition exhibited good weldability and sufficient hardenability for 4-in.-thick plates. An 80-ton heat of this composition was produced, and the susceptibility of this steel to embrittlement during stress-relieving treatments was compared with that of a standard-composition 5Ni-Cr-Mo-V steel. The two steels were compared with and without 1 per cent prestrain. The modified-composition 5Ni-Cr-Mo-V steel exhibited about half the embrittlement of the standard composition. Embrittlement increased as the stress-relieving time increased and as the cooling rate from the stress-relieving temperature decreased. Prestraining produced no significant changes in the response of the steels to embrittlement.
