در تحقیق حاضر پدیده گرافیت زایی فولاد هایپر یوتکتویید تجاری (CK100) از ساختار اولیه مارتنزیتی حین عملیات حرارتی بازپخت مورد بررسی قرار گرفته است. مشاهدات صورت گرفته توسط میکروسکوپ های نوری و الکترونی روبشی نشان داد که ذرات ...

In the present experimental study, the influence of primary martensitic structure on acceleration of graphitization process in hypereutectoid steels during subsequent heat treatment cycle was investigated by using of optical ...

In spite of excellent machinability and wear resistance of graphitic steels, they exhibit low hardness and mechanical properties due to the presence of a ferritic matrix, soft graphite phase and need for prolonged annealing ...

Nanotechnology, a rapidly growing science, is focused on the integration of fields such as physics, biology, engineering, chemistry, computer science and others. Over a few years the use of nanoparticles has brought a new ...

Graphitization process in steel is referred to the decomposition of meta-stable cementite phase to more stable phases of graphite and ferrite. I n steels this transformation often occurs in the range of 600-700°C. In common ...
