报告题目(中文):高性能板钢的合金化
报告题目(英文):Alloying Concepts for High Performance Plate Steels
报告内容简介:Additions of Mo and Nb to low carbon plate steel allow increasing both, yield and tensile strength. The two alloying elements have beneficial individual effects and reveal interesting synergies when alloyed in combination. Nb is particularly effective in retarding recrystallization. This is the basis for efficient grain refinement improving strength and toughness simultaneously. Secondly, Nb provides a high potential for precipitation hardening. Mo is a potent hardenability element as it retards ferrite formation and lowers the bainite transformation temperature. It also assists Nb in retarding recrystallization and optimizes the precipitation hardening effect of Nb. Both elements significantly enhance the tempering resistance. The simultaneous presence of solute Mo or Nb also increases the effectiveness of B microalloying. Solute B segregated to the austenite grain boundary efficiently inhibits pro-eutectoid ferrite nucleation. On the other hand B strongly enhances the recrystallization retarding effect of Nb. A well-considered coordination of these alloying elements with the plate processing conditions is required to exploit their metallurgical effects in obtaining the optimum mechanical properties.
