摘要

热锻模在使用过程中受到严重的热机械应力，导致微观组织变化导致模具失效。因此，锻造行业的研究重点是研究热锻模在使用过程中的微观组织变化。对双回火aisih11钢模具进行了100和500次锻造冲程的热锻试验。进一步对模具表面进行了显微组织分析。通过对模具表面的显微组织分析，发现随着锻造循环次数的增加，富铬碳化物的尺寸逐渐增大。进一步对碳化物的分布进行了定量分析。

Influence of hot forging on microstructure in double tempered H11 hot forging dies

Hot forging dies are exposed to severe in-service thermomechanical stress, which induces microstructural changes leading to die failures. Thus, research in forging industries is focussed on study of in-service microstructural changes in hot forging dies. Hot forging tests were performed on double tempered AISI H11 steel dies for test duration of 100 and 500 forging strokes. Further, microstructural analyses were conducted on die surface. From microstructural analyses on die surface, it was revealed that chromium rich carbides grows in size with increase in number of forging cycles. Further, quantitative analysis of the carbide distribution was performed.

期刊介绍： Metallurgical Research and Technology (MRT) is a peer-reviewed bi-monthly journal publishing original high-quality research papers in areas ranging from process metallurgy to metal product properties and applications of ferrous and non-ferrous metals and alloys, including light-metals. It covers also the materials involved in the metal processing as ores, refractories and slags. The journal is listed in the citation index Web of Science and has an Impact Factor. It is highly concerned by the technological innovation as a support of the metallurgical industry at a time when it has to tackle severe challenges like energy, raw materials, sustainability, environment... Strengthening and enhancing the dialogue between science and industry is at the heart of the scope of MRT. This is why it welcomes manuscripts focusing on industrial practice, as well as basic metallurgical knowledge or review articles.
