摘要 长期以来，锻造应用工具和工具系统的研究和开发在生产技术领域发挥着重要作用。由于磨损过程是锻模失效的最常见原因，因此本研究的主要目标是通过新的合金概念来减少磨损，从而提高这些模具的耐用性。关注了锰含量增加对共析温度（Ac1b 温度）降低的影响。这样，就可以对锻造过程中循环加热和冷却引起的边缘层显微组织的变化产生积极的影响。特别是与标准合金相比，白层的范围扩大了，并且由循环软化退火钢组成的下层的影响减少了。本文显示了最多 300 个锻造循环的结果。
Abstract For a long time the research and development of tools and tool systems for forging applications play an important role in the field of production technologies. Due to the fact that wear processes are the most common cause for the failure of forging dies, the main goal of the presented work is to achieve a wear reduction and thereby an enhanced durability of these dies by a new alloy concept. Attention was paid to the influence of an increased manganese content on the reduction of the eutectoid-temperature (Ac1b-temperature). In this way, it was possible to take a positive influence on the changes in the microstructure of the edge layer caused by the cyclic heating and cooling during forging. Especially the range of the white layer is enlarged and the influence of the lower layers consisting of cyclic soft-annealed steel is reduced, compared to the standard alloys. This article shows the results for up to 300 forging cycles.
