بررسی تاثیر حضور ذرات اکسید تیتانیوم در جلوگیری از رشد دانههای NiTi در فرآیند تفجوشی [PDF]
یکی از مشکلات تفجوشی مواد نانو اندازه، رشد دانه در حین این فرایند است. از آنجایی که کاراییهای منحصر بهفرد مواد نانو تا زمانی که در محدوده اندازه زیر 100 نانومتر باشند، وجود دارد، بهمنظور جلوگیری از این پدیده و کاهش سرعت رشد دانهها راهکارهای مختلفی ...
