TLDR
In this article, plate hot rolling conditions were reproduced in low carbon Ti-Mo microalloyed steel through laboratory simulation tests to generate different hot-rolled microstructures, and a rapid heating process was applied in order to simulate induction heat treatment conditions.Abstract:
Cost-effective advanced design concepts are becoming more common in the production of thick plates in order to meet demanding market requirements Accordingly, precipitation strengthening mechanisms are extensively employed in thin strip products, because they enhance the final properties by using a coiling optimization strategy Nevertheless, and specifically for thick plate production, the formation of effective precipitation during continuous cooling after hot rolling is more challenging With the aim of gaining further knowledge about this strengthening mechanism, plate hot rolling conditions were reproduced in low carbon Ti-Mo microalloyed steel through laboratory simulation tests to generate different hot-rolled microstructures Subsequently, a rapid heating process was applied in order to simulate induction heat treatment conditions The results indicated that the nature of the matrix microstructure (ie, ferrite, bainite) affects the achieved precipitation hardening, while the balance between strength and toughness depends on the hot-rolled microstructureread more

Effect of heat treatment on the mechanical properties and microstructure of HSLA steels processed by various technologies
A.V. Zavdoveev,V.D. Poznyakov,Thierry Baudin,Massimo Rogante,Hyoung Seop Kim,Mark Heaton,Yuriy Demchenko,Victor Zhukov,Mykola Skoryk +8 more
TL;DR: In this paper, the authors investigated the influence of heat treatment on the microstructure and properties of high strength low-alloyed steels obtained using various technologies and found that the structural stability during high-temperature heat treatment is controlled by a number of factors such as heating temperature and holding time, grain growth, accumulated strain, the presence of deformation texture, steel deoxidation, and dissolution/uncontrolled growth of precipitations.
