Mechanism of hot-shortness in leaded and tellurized free-machining steels
TL;DR: In this paper, the authors investigated the mechanism of hot shortness in 12L14 + Te steels, which might lead to a hot-rolling practice to minimize the high yield losses in this grade.
Patent
Free machining steel with bismuth
TL;DR: A free machining steel shape containing bismuth which functions as a liquid metal embrittler is described in this article, where the authors limit the size of inclusions to less than five microns.
Patent
Bismuth containing steel
TL;DR: In this paper, a free machining cast steel shape containing bismuth which functions as a liquid metal embrittler is enhanced by restricting the total amount of ingredients which lower the wetting ability of the bistuth to less than the bistsuth content and by controlling the amount of strengthening elements added to the steel.
Journal ArticleDOI
Effect of Sulfur and Zirconium on the Machinability and Mechanical Properties of AISI 1045 Steels
TL;DR: In this article, the effects of small increases of sulfur and addition of zirconium in conjunction with sulfur on the machinability and mechanical properties of laboratory-produced AISI 1045 steels have been investigated.
Patent
Method and alloy for introducing machinability increasing ingredients to steel
TL;DR: In this article, lead, bismuth and tellurium and/or sulfur are added to steel to increase the machinability of the steel, in an addition alloy consisting essentially of 5-40 parts lead, 5- 40 parts Bismuth, and up to 6 parts telluranium and 25 parts sulfur.
