Abstract

Metallic glasses, also known as amorphous alloys, have attracted great attention due to their unique physical and chemical properties. In this study, the crystallization behaviors of Ni35.116Co24.184W23.7B17 and Ni32.75Co22.55W23.7B15Nb6 amorphous alloys were investigated. The alloys with amorphous structure were synthesized by vacuum suction casting following vacuum arc melting. As a result of heat treatments, composite materials reinforced with CoWB ternary borides were obtained. The phase compositions and microstructures of both the master alloys and the composite samples produced from amorphous alloys under different heat treatment conditions were characterized. Continuous heating diagrams for both compositions were constructed using the Kissinger kinetic approach, and their experimental validity was discussed. The addition of Nb to the Ni–Co–W–B alloy was observed to increase the characteristic temperatures to a certain extent. The differences between the crystallization behavior from the liquid state and that from the amorphous state upon heat treatment were demonstrated. On the other hand, it was determined that the addition of Nb to the composition led to the precipitation of Ni₄Nb and B₂Co₃ phases alongside CoWB crystals. To examine the mechanical properties, the hardness values of the alloys and the produced composites were measured. The hardness values of the Ni35.116Co24.184W23.7B17 and Ni32.75Co22.55W23.7B15Nb6 master alloys were approximately 650 Hv. The hardness values of the amorphous alloys were determined to be 1231 Hv and 1259 Hv, respectively. On the other hand, it was observed that the hardness of the composite samples produced by heat treatment increased with longer isothermal heat treatment durations.

Özet

Metalik camlar, diğer adıyla amorf alaşımlar, sahip oldukları benzersiz fiziksel ve kimyasal özellikleri nedeniyle büyük ilgi görmektedir Bu çalışmada, Ni35.116Co24.184W23.7B17 ve Ni32.75Co22.55W23.7B15Nb6 amorf alaşımlarının kristallenme davranışları incelenmiştir. Amorf yapıya sahip alaşımlar, vakum ark ergitme işlemi sonrasında vakum emmeli döküm yöntemiyle sentezlenmiştir. Isıl işlemler sonucunda CoWB üçlü borür (ternary boride) takviyeli kompozit malzemeler elde edilmiştir. Master alaşımların ve farklı koşullar altındaki ısıl işlemlerle amorf alaşımlardan üretilen kompozit numunelerin faz içerikleri ve mikroyapıları karakterize edilmiştir. Kissinger kinetik yaklaşımı kullanılarak her iki kompozisyon için sürekli ısıtma diyagramları oluşturulmuş ve deneysel olarak doğrulukları tartışılmıştır. Nb elementinin Ni-Co-W-B alaşımına eklenmesi ile karakteristik sıcaklıkların belirli ölçüde arttığı gözlemlenmiştir. Alaşımların sıvı halden kristallenme davranışı ile amorf halden ısıl işlem sonucu kristallenme davranışı arasındaki farklılık gösterilmiştir. Kompozisyona Nb ilavesinin, CoWB kristallerinin yanında Ni4Nb ve B2Co3 fazları çökelmesine neden olduğu belirlenmiştir. Mekanik özeliklerin incelenmesi amacıyla alaşımların ve üretilen kompozitlerin sertlik değerleri ölçülmüştür. Ni35.116Co24.184W23.7B17 ve Ni32.75Co22.55W23.7B15Nb6 master alaşımlarının sertlik değerleri yaklaşık 650 Hv olarak ölçülmüştür. Amorf alaşımlarının sertlik değerlerinin sırasıyla 1231 ve 1259 Hv olduğu tespit edilmiştir. Diğer yandan ısıl işlemler ile üretilen kompozit numunelerde sertlik değerlerinin izotermal ısıl işlem süresi arttıkça yükseldiği görülmüştür.
