Abstract    The application of Inconel 713C is very vast in different industries such as in automobiles, aircrafts, boilers and turbines. In this paper, Inconel 713C specimens were solutionized at 1000 and 1200 C for 1 hours in order to study changes in phases and the structure of alloy to modify the γ' phase. The optical and the scanning electron microscopy were used to investigate the structure and the energy dispersive spectroscopic (EDS) and the X-ray diffraction (XRD) were applied to identify the composition and phase changes. Results showed that the solutioning heat treatment at 1000 C for 1 hour caused to participate Cr23C6, but when the temperature of heat treatment increased to 1200C, chromium carbides solutionized in the γ matrix. Besides, by applying the heat treatment at temperature of 1000 C, the γ' phase dissolved in (200) and (220) plane and this phase in the plane of (111) had the best stability. However the (220) plane of γ' phase was stable thermodynamically for the specimen without the heat treatment. Phases of Ni5Al3 and Al0.42Ni0.58 were observed at the temperatures of 1000 and 1200 C, respectively. In addition, as the heat treatment temperature increased from 1000 to 1200 C the new phase of AlNi3C0.5 solutionized in the γ matrix.

چکیده    کاربرد اینکونل 713C در صنایع مختلف از جمله صنعت خودروسازی، هواپیماسازی، توربینها و بویلرها گسترده شده است. در این مقاله، نمونههایی از جنس اینکونل 713C در دماهای 1000 و 1200 درجه سانتیگراد مورد عملیات حلسازی قرار گرفته است تا تغییرات فازی و ریزساختاری آلیاژ به منظور بهینه کردن میزان فاز گاماپرایم مورد ارزیابی قرار گیرد. میکروسکوپ نوری و الکترونی برای بررسی ریزساختار، روش طیفسنحی تفرق انرژی و تفرق پرتو ایکس به منظور مطالعه تغییرات فاز و ترکیب استفاده شدند. نتایج نشان میدهد که عملیات حلسازی در دمای 1000 درجه سانتیگراد و زمان یک ساعت موجب رسوبدهی کاربید کروم (Cr23C6) میگردد، اما زمانی که دمای عملیات حرارتی به 1200 درجه سانتیگراد برسد کاربید کروم در زمینه گاما حل میشود. در ضمن اینکه عملیات حرارتی در دمای 1000 درجه سانتیگراد موجب میشود که فاز گاماپرایم در صفحات (200) و (220) حل شده اما در صفحه (111) بیشترین پایداری را داشته باشد. هرچند که پایداری فاز گاماپرایم در صفحه (220) برای نمونه بدون عملیات حرارتی از لحاظ ترمودینامیکی پایدار است. فازهای Ni5Al3 و Al0.42Ni0.58 به ترتیب در دمای 1000 و 1200 درجه سانتیگراد پایدار هستند. علاوه بر آن، زمانی که دمای عملیات حرارتی از 1000 به 1200 درجه سانتیگراد افزایش یابد، فاز جدید AlNi3C0.5 در زمینه گاما هم حل میشود.
