Partikül Boyutunun ve B4C Katkı Oranının Al-B4C Kompozitlerin Mekanik ve Mikroyapı Özellikleri Üzerine Olan Etkisi

Abstract

Bu çalışmada, Al-B4C kompozitler farklı partikül boyutlarında (B4C: 3.5 ve 20 um) ve takviye oranlarında (% B4C: 1, 3, 6, 9, 12, 15, 30) toz metalürjisi yöntemiyle üretilmiştir. Kompozitlerin görünür yoğunluğu, basma dayanımı ve Vickers sertliği sırasıyla; Arşimet yoğunluk ölçüm cihazı, üniversal test makinesi ve mikro Vickers sertlik ölçüm cihazıyla belirlenmiştir. Üretilen kompozitlerin faz ve mikro-yapı analizi sırasıyla; X-ışını kırınımı cihazı ve taramalı elektron mikroskobu kullanılarak analiz edilmiştir. Test sonuçlarına göre; en yüksek mikro Vickers sertliği (68.8 HV), görünür yoğunluk (2.61 g/cm3), basma dayanımı (242 MPa) ve en düşük gözeneklilik oranı (% 1.4) %30 B4C katkı oranına ve 3.5 µm B4C partikül boyutuna sahip Al-B4C kompozit yapıda elde edilmiştir. Saf alüminyum ile karşılaştırıldığında Al-%30B4C kompozitin Vickers sertliğinin ve basma dayanımının sırasıyla; %129.3 ve %165.9 oranında arttığı tespit edilmiştir.

The Influence of Particle Size and Reinforcement Rate of B4C on Mechanical and Microstructure Properties of Al-B4C Composites

Abstract

In this study, Al-B4C composites were produced with various particle sizes (B4C: 3.5 and 20 µm) and reinforcement rates (B4C%: 1, 3, 6, 9, 12, 15, 30%) by the powder metallurgy method. The apparent density, compressive strength, and Vickers hardness of the composites were determined by Archimedes’ density meter, universal test machine, and micro Vickers hardness measurement device, respectively. The phase and microstructural analysis of the fabricated composites were analyzed using an X-ray diffraction device and scanning electron microscope, respectively. From the test results, the highest micro Vickers hardness (68.8 HV), apparent density (2.61 g/cm3), compressive strength (242 MPa), and minimum porosity (1.4%) were determined at 3.5 µm particle size and 30% reinforcement rate of B4C. The enhancement in Vickers hardness and compressive strength of Al-30%B4C composite was detected as +129.3% and +165.9% compared with pure aluminum.
