Thesis Title: Processing Effects on Mechanical Properties and Fracture of Quenched-and-Tempered 4340 Steel
Abstract: Tempered martensite embrittlement (TME) degrades the properties of medium carbon steels over a range of tempering temperatures. Improved understanding of how the mechanisms contributing to TME are affected by short-time tempering may be helpful for avoiding this phenomenon. Induction tempering occurs in a different time-temperature regime (shorter time at higher temperature) than that of conventional tempering, and the tempering stages and conditions for the onset of TME are not well defined for short-time tempering.
