Ti50Ni27Nb20Ta3 Şekil Hatırlamalı Alaşımda Isıl İşlemlerin Faz Dönüşüm Histeresizi ve Termal Aktivasyon Enerjisi Üzerine Etkilerinin İncelenmesi
Abstract
Bu çalışmada dörtlü TiNiNbTa alaşımına farklı ısıl işlemler uygulanarak alaşımın termal parametreleri üzerine ısıl işlemlerin etkileri incelendi. Isıl işlem sıcaklıkları 700℃, 800℃ ve 900℃ seçildi. Isıl işlem yapılan alaşımların DSC eğrileri farklı ısıtma-soğutma hızına bağlı olarak alındı. Isıl işlem sıcaklığını artmasına bağlı alaşımın dönüşüm sıcaklıklarının azaldığı belirlendi. Fakat artan ısıl işlem sıcaklığı ile termal aktivasyon enerjisinin önemli derecede arttığı gözlendi. Ayrıca ısıl işlem sıcaklığının artması austenite faz pik minumununu (Ap) ve dönüşüm histeresizini (Hf) önemli derecede azalttığı gözlendi.

Investigation of The Effects of Heat Treatments on Phase Transformation Hysteresis and Thermal Activation Energy in Ti50Ni27Nb20Ta3 Shape Memory Alloy
Abstract
In this study, the effects of heat treatments on the thermal parameters of the alloy were investigated by applying different heat treatments to the quaternary TiNiNbTa alloy. Heat treatment temperatures of 700℃, 800℃ and 900℃ were selected. DSC curves of heat-treated alloys were taken depending on different heating-cooling rates. It was determined that the transformation temperatures of the alloy decreased due to the increase in the heat treatment temperature. However, it was observed that the thermal activation energy increased significantly with increasing heat treatment temperature. In addition, it was observed that increasing the heat treatment temperature significantly decreased the austenite phase peak minimum (Ap) and conversion hysteresis (Hf).
