Abstract
Building the Nano composites for getting material with combinational properties and improving properties of currently used material has been taken significant attention. One of the ways of building Nano composites is using a method known as powder metallurgy. Because with this method not only wastes are decreased to minimum but we can also mix the materials with high melting point with the materials with low melting point which is a difficult thing to do with foundry method. In this research titanium alloy for improvement in its mechanical properties is mixed with silicon carbide reinforcing. Knowing the fact that silicon carbide is in Nano scale these two materials start building Nano composites. The powder metallurgy method is the best way for mixing these two materials together. To make sure that the properties of the made alloy is similar to the foundry alloy, the static compression methods are used. For comparison the results, two factors such as the Nano silicon carbide percentage and the static compression pressure are. Also, Density experiment, observation of grain boundaries using a scanning electron microscope, pressure test and the hardness experiment was done on it.

Abstract [Persian]
امروزه ساخت نانوکامپوزیت‌ها، برای دستیابی به موادی با خواص ترکیبی و بهبود خاصیت مواد، بسیار مورد توجه محققان قرار گرفته است. یکی از بهترین روش‌های ساخت نانوکامپوزیت‌ها استفاده از روش متالورژی پودر است. زیرا با این روش علاوه بر این‌که ضایعات به حداقل می‌رسند می‌توان موادی را که دارای نقطه‌ی ذوب بالا هستند با مواد دارای نقطه‌ی ذوب پایین ترکیب نمود که این کار با روش ریخته‌گری بسیار دشوار خواهد بود. در این تحقیق آلیاژ تیتانیوم برای بهبود خواص مکانیکی با تقویت‌کننده‌ی کاربید سیلیسیم ترکیب شده است. از آن‌جا که پودر تقویت‌کننده‌ی کاربید سیلیسیم در مقیاس نانو می باشد، این دو ماده با هم تشکیل یک نانو کامپوزیت می‌دهند. روش متالورژی پودر بهترین راه برای ترکیب این دو ماده با هم می باشد. در این تحقیق برای تولید این نانو کامپوزیت، از روش فشردن استاتیکی(دستگاه پرس سرد) استفاده شده است. برای مقایسه، سه درصد مختلف تقویت کننده‌ی نانوپودر کاربید سیلیسیم و همچنین، سه فشار پرس مورد استفاده قرار گرفته است. همچنین، آزمایش‌های چگالی، مشاهده مرزبندی دانه‌ها توسط میکروسکوپ الکترونی رویشی، تست فشار و آزمایش سختی روی آن‌ها انجام گرفت.
