Book Description
The fatigue crack initiation life of AISI 1018 steel was investigated using compact tension specimens having sharp notch root radii. The data were analyzed using two methods for predicting initiation in strain cycling experiments. Also, another approach in which initiation is related to the stress intensity factor was developed. The next phase, that of propagation, was studied using AISI 1018 steel and a new high strength steel HY-180. The crack propagation data obtained for both steels tested in air can be described accurately by the power law first suggested by Paris, da/dN = C(.delta. K)/sup n/, where a is the crack length, N the number of cycles, and C and n are material constants. However, the exponent n was found to be two times larger for AISI 1018 steel than HY-180 steel.

Corrosion in the Petrochemical Industry, Second Edition
Author:
Publisher: ASM International
ISBN: 1627080945
Category : Technology & Engineering
Languages : en
Pages : 426
Book Description
Originally published in 1994, this second edition of Corrosion in the Petrochemical Industry collects peer-reviewed articles written by experts in the field of corrosion that were specifically chosen for this book because of their relevance to the petrochemical industry. This edition expands coverage of the different forms of corrosion, including the effects of metallurgical variables on the corrosion of several alloys. It discusses protection methods, including discussion of corrosion inhibitors and corrosion resistance of aluminum, magnesium, stainless steels, and nickels. It also includes a section devoted specifically to petroleum and petrochemical industry related issues.

Fatigue-Crack Propagation in Some Ultrahigh-Strength Steels

Pages : 26
Book Description
Fatigue-crack propagation studies were carried out on some ultrahigh-strength steels in controlled environments using the fracture-mechanics approach. The steels investigated include a medium-carbon low-alloy ultrahigh-strength steel tempered to two strength and toughness levels, a 250-grade 18Ni maraging steel, and a 300-grade 18Ni steel. The results indicate that, in the inert environment, the rates of fatigue-crack propagation in these steels are about the same and show no obvious correlation with other mechanical properties of the steels. The sensitivity of the rates of fatigue-crack propagation to the presence of moisture in the test environment shows rough correlation with plane-strain fracture toughness for steels of similar composition. The role of water vapor in promoting fatigue-crack propagation is considered. The results are also discussed in terms of existing theories and metallographic observations.
