Improvement and identification of mechanical properties in forged parts by immediate post-forming after hot forging on different temperature levels by influencing microstructure of tempering steel

在该项目中，锻件的微观组织应该受到锻造工艺的不同方面的影响。此外，这些影响将通过评估典型的材料性能来分类。一方面利用变形过程中的动态再结晶效应细化组织，另一方面利用二次变形进行形变处理。通过这种组合，可以在大批量成形零件的激冷回火钢中获得超细的组织。细化晶粒还可以提高强度和韧性。为了获得变形和处理后材料的可比力学性能的可靠数值，将进行标准化试验。结果将与常规制造的零件的结果一起附加显示在理解中。

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.
