چکیده مقاله :
توجه به سرامیک‌های فوق دمابالا به دلیل فناوری‌های قرن بیست و یکم و تلاش برای ساخت سامانه‌های حفاظت حرارتی قابل‌استفاده مجدد و سایر ترکیبات موردنیاز برای نسل‌های آینده وسایل نقلیه هوا فضایی مافوق صوت، به میزان قابل‌توجهی افزایش یافته است. در این پژوهش افزودن کاربید زیرکونیم (ZrC) به‌عنوان تقویت‌کننده در مقادیر 5 تا 40 درصد حجمی بر رفتار خواص مکانیکی و مکانیزم رشد ترک ZrB2-SiCn/m (دارای 3 درصد حجمی سیلیکون نیترید Si3N4) موردبررسی قرار گرفت. جهت ارزیابی از سختی سنجی ویکرز، چگالی ارشمیدس و تصاویر میکروسکوپی الکترونی روبشی استفاده شد. نتـایج نشان داد؛ میزان انقباض حجمی با افزایش میزان ZrC کاهش می‌یابد. بالاترین افزایش چگالی نسبی نمونهها با افزایش مقدار ZrC در نمونه ZrB2-SiCn/m-30%ZrC به میزان (04/97) درصد است. با توجه به این‌که ترك نميتواند از ميان ذرات ZrC عبور کند؛ این ذرات از طريق دو سازوکار تغيير مسير ترك و پل‌زنی ترك باعث افزايش چقرمگي ميشوند. همچنین نمونه حاوی 30 درصد حجمی ZrC بیشترین مقدار چقرمگی شکست (MPa.M1/226/4) و سختی (GPa 3/16) را دارد.
Attention to ultrahigh temperature ceramics has increased significantly due to the advancements in 21st century technologies and efforts to develop reusable thermal protection systems and other compounds required for future generations of hypersonic aerospace vehicles. In this research, the addition of zirconium carbide (ZrC) as a reinforcement in volumes ranging from 5 to 40% was investigated for its impact on the mechanical properties and crack growth behavior of ZrB2-SiCn/m composites) with 3% silicon nitride (Si3N4) by volume) The results indicate that volumetric shrinkage decreases with increasing ZrC content. The highest relative density increase was observed in the ZrB2-SiCn/m-30%ZrC sample, with a percentage increase of 97.04%. Since cracks cannot pass through the ZrC particles, these particles increase the toughness by altering the crack path and bridging the crack. Moreover, the sample containing 30% volume fraction of ZrC exhibited the highest fracture toughness (4.26 MPa.m1/2) and hardness (16.3 GPa).
