LITERATURE SURVEY ON THE INFLUENCE OF ALLOY ELEMENTS ON THE FRACTURE TOUGHNESS OF HIGH STRENGTH STEELS.
Abstract
A literature survey was conducted to summarize the known effects of solid solution additions on the fracture toughness of high-strength steels. The results indicate that nickel is the singular alloy addition that consistently improves toughness while manganese has a detrimental effect. In the range of compositions usually employed, variations in the percentage of carbide formers produces no well defined change in fracture toughness. Silicon has a marked effect on retarding the tempering reactions and some results indicate that when it is added to vacuum melted 4340 a significant increase in toughness can result. At present the use of secondary hardening mechanisms in the low alloy martensitic steels has not produced any significant improvement in toughness. (Author)
