Toz Metalurjisi Metoduyla Üretilen Distaloy AE Alaşımlarının Isı Akışı Davranışları

Öz

Alaşımları teknikleri ön alaşımlı, ön karışımlı ve difüzyon-bağlı tozla olmak üzere sınıflandırılır. Bu çalışmada kullanılan Distaloy AE alaşımı Fe, Ni ve Mo alaşım elementleri içeren bir difüzyon-bağlı alaşım çeşididir ve yüksek dayanımlı mikroyapıya sahiptir. Bu çalışmada toz metalürjisi metoduyla üretilen Distaloy AE alaşımlarının sertlik, yoğunluk ve ısıl akışları çalışılmıştır. Bu malzemelerin sertlik ve yoğunluk ölçümleri Brinell sertlik ölçümleri ve Archimedes suyun kaldırma tekniği kullanılmıştır ve Diferansiyel Taramalı Kalorimetre (DSC) cihazı kullanılarak alaşımların ısıl akışları saptanmıştır. Sonuçlar alaşımların SEM fotoğrafları, EDS spektrumlarıyla desteklenmiştir ve ayrıca alaşımların kristal yapıları XRD desenleriyle saptanmıştır.

Heat Flow Behaviours of Distaloy AE Alloys Produced by Powder Metallurgy

Öz

The alloying techniques are classified with pre-alloyed, pre-mixed and diffusion-bonded powders. Distaloy AE alloy used in this study is type of diffusion-bonded alloy including of Fe, Ni and Mo alloying elements and has high strengthening microstructures. In this study; hardness, density and heat flows distaloy AE samples prepared by powder metallurgy method performed. As hardness and density measurements of these samples, Brinell hardness measurements and Archimedes water displacement technique performed and heat flows of these alloys determined using Differential Scanning Calorimetry (DSC) device. These results supported by SEM images, EDS spectrums of alloys and also, crystal structures of these alloys determined by XRD patterns.
