Influence of heat input on the changes in the microstructure and fracture behavior of laser welded 800MPa grade high-strength low-alloy steel
TL;DR: In this paper, high-strength low-alloy (HSLA) steels with a yield strength of 800 MPa and a thickness of 8 mm were subjected to laser welding to address the problem of loss of strength in the welded joint.

Phase Transformation under Continuous Cooling Conditions in Medium Carbon Microalloyed Steels
TL;DR: In this article, the influence of the alloying and microalloying elements on phase transformation at different cooling rates was studied and the continuous cooling transformation diagrams were plotted in order to optimize the heat treatment and improve the mechanical properties, the range of cooling rates leading to a fully bainitic microstructure without ferrite, pearlite and especially without martensite was determined.
