Steels: Processing, Structure, And Performance
TL;DR: In this article, the authors present a tutorial for steel making, alloying, microstructure, deformation, fracture and properties of major steel types ranging from low-carbon sheet steels, pearlitic rail and wire steels to quench and tempered medium-and high-carbon martensitic steels.

Measurement of residual stress in arc welded lap joints by cosα X-ray diffraction method
TL;DR: In this article, the authors measured the residual stress of lap joints of thin steel sheets by the cosα X-ray diffraction method and compared with the numerical simulation, and found that the longitudinal residual stress in the region near the weld is close to the yield strength of the base metal.

Transition from bainite to acicular ferrite in reheated Fe–Cr–C weld deposits
TL;DR: In this paper, a theoretical analysis indicates that bainitic transformation is prevented from developing at the allotriomorphic ferrite/austenite boundaries by the carbon concentration field present in the austenite.
