چکیده

کامپوزیت‌های(Zr55Cu30Al10Ni5)100-xNb(x= 0, 2)   W/به روش فلزخورانی در دمای 950 درجه سانتیگراد به مدت 15 دقیقه تولید شدند. خواص ساختاری و مکانیکی کامپوزیت‌های تولید شده با این روش، به ترتیب توسط میکروسکوپ الکترونی روبشی و آزمون فشار تک محوری مورد بررسی قرار گرفتند. بر اساس نتایج حاصل از خواص مکانیکی و ریزساختاری، در نمونه X=2، سطح شکست عمدتا از نوع سطح شکست رگه ای بوده و با افزایش میزان چگالی ساختارهای رگه ای، شکل پذیری پلاستیک نیز به 28 درصد افزایش یافت. همچنین در نمونه بدون افزودنی نیوبیم، فازهای بین فلزی ثانویه W2Zr) و (W5Zr3 (که خود از محل‌های جوانه زنی ترک هستند) به عنوان مکان‌های تمرکز تنش عمل کرده و سطح شکست در این نمونه کامپوزیتی عمدتا از نوع مسطح بوده و با تبدیل سریع باندهای برشی به ترک، شکل پذیری پلاستیک کامپوزیت کاهش یافت.
