“…Tool selection is an important decision when machining nickel-based alloys. Good wear resistance, high strength and toughness, elevated hardness and toughness, and chemical stability at elevated temperatures are required for the machining of these difficult-to-cut materials [23]. Ceramic and carbide tools are mainly recommended for the turning operations of Ni alloys [3,13] (ceramic tools for roughing and semi-finishing turning, and coated carbide tools for finishing turning).…”

“…Flank wear, chipping, and catastrophic failures are induced by adhesion and abrasion at the clearance surface [21,22].Tool selection is an important decision when machining nickel-based alloys. Good wear resistance, high strength and toughness, elevated hardness and toughness, and chemical stability at elevated temperatures are required for the machining of these difficult-to-cut materials [23]. Ceramic and carbide tools are mainly recommended for the turning operations of Ni alloys [3,13] (ceramic tools for roughing and semi-finishing turning, and coated carbide tools for finishing turning).Ceramic tools have low mechanical and thermal shock resistance [24,25], low thermal conductivity, a high thermal expansion coefficient, and low toughness [26].…”

“…Nikel, diğer ana alaşım metalleri olan krom, demir ve kobalt yanında çok sayıda elementle belirli oranlarda alaşımlanarak süper alaşım adı verilen, oldukça yüksek sıcaklık ve korozyon direncine sahip alaşımları meydana getirebilir [2]. Nikel bazlı süper alaşımlar bu özellikleri nedeniyle yüksek sıcaklık ve korozyon direnci gerektiren havacılık ve uzay, petrokimya, enerji makineleri ve güç sistemleri endüstrileri uygulamalarında türbin diskleri, kanatçıklar, borular, bağlantı ekipmanları gibi yüksek sıcaklık ve korozyona maruz kalabilecek parçaların üretiminde sıkça kullanılmaktadır [3][4][5][6][7]23]. Nikel esaslı süper alaşımlar, sahip oldukları yüksek düzeydeki mekanik özellikleri, yüksek sıcaklıklarda mekanik özelliklerini koruyabilme kabiliyeti ve malzemenin zayıf termal iletkenlik kapasitesinin etkisiyle, talaşlı imalat süreçlerinde işlenebilirlik problemlerinin ortaya çıkmasına neden olmaktadırlar.…”
