项目摘要
In the proposed project, the microstructure of forged components should be influenced by different aspects of forging process. Furthermore these influences will be classified by evaluating typical material properties. On one hand the effect of dynamic recrystallization during the deforming process will be used to refine the microstructure, on the other hand a second deforming operation will be used to apply a thermomechanical treatment. By this combination an ultra-fine gained microstructure should be reached in the exanimated tempering steel in parts manufactured by massive forming processes. Grain refinement improves strength and toughness as well. To obtain reliable values of comparable mechanical properties of the deformed and treated material, standardized tests will be carried out. The results will be shown additionally in comprehension with results of conventionally manufactured parts.
在拟议的项目中,锻造部件的显微组织应受到锻造工艺不同方面的影响。此外,这些影响将通过评估典型的材料特性进行分类。一方面利用变形过程中的动态再结晶作用细化组织,另一方面利用二次变形进行形变热处理。通过这种组合,在通过大规模成型工艺制造的零件中,在经回火的钢中应达到超细获得的显微组织。晶粒细化也提高了强度和韧性。为了获得变形和处理材料的可比机械性能的可靠值,将进行标准化试验。结果将与常规制造的部件的结果一起显示。
