Ultra-high-strength bainitic steels
WebIn this work, the bake hardening mechanism of the complex phase (CP) steel CP980 was explored by comparing it with that of DP1180, which has a clear bake hardening mechanism and a carbon content similar to that of CP980. By analyzing the bake hardening response and the microstructural changes of the two steels, we found that the bake hardening ...

Web30 Dec 2024 · The hole-expansion ratio (HER) is a measure of stretch flangeability performance for automotive structural steels [].With the advanced-high strength steels nowadays becoming extensively employed in fabricating automobile structural parts to improve fuel efficiency and to eliminate gas emissions [2,3,4,5,6,7,8], the cracking caused …
WebGood combinations of strength and elongation and strength and stretch-flangeability were achieved when the TBF steel was austempered at 450-500°C and 425-475°C, respectively. These good combinations were caused by fine lath structure and a large amount of metastable retained austenite film. Webof strength, is illustrated in Fig. 4, along with the T0 0 curves. Commercial Applications We demonstrated above, that a knowledge of the mechanism of bainite formation can be exploited towards the design of new steels. These concepts have now been used both in the development of novel ultra–high strength steels with strength and toughness ...
WebBainitic ferrite plate thickness evolution during isothermal transformation was followed at the same holding temperatures in two nanostructured steels containing (in wt.%) 1C-2Si and 0.4C-3Si. A dynamic picture of how the bainitic transformation evolves was obtained from the characterization of the microstructure present at room temperature after full and … Web7 Apr 2024 · The aim of this work was to develop a novel bainitic steel that will be specifically dedicated to achieving a high degree of refinement (nano- or submicron scale) along with increased thermal stability of the structure at elevated temperatures.
