到目前為止，許多研究開發出具有臨界尺寸直至厘米級的銅基金屬玻璃。然而，已知的合金系統基本上限於銅-鋯基合金系統，且新形狀BMG複合材料的開發對於拓展金屬玻璃發展和改善這些複合材料的性質是必不可少的。最近，在Cu-Ni-Ti三元系中的L ⇔ TiCu + TiNi成分範圍附近發現了新的BMG。獲得直徑為1和1.5mm的棒狀金屬玻璃，其也表現出良好的機械性能。

在本研究中，用計算相圖（CALPHAD）方法來預測金屬玻璃形成區域。利用文獻中的參數，重新評估了Cu-Ni-Ti三元相圖。在建立合理的Cu-Ni-Ti熱力學數據庫來描述每個相後，可以繪製二元和三元相圖。通過結合抑制金屬間化合物（IMC）相的亞穩相圖，液體互溶間隙和旋節線曲線，將熱力學參數用於預測金屬玻璃區域。預測區域與本研究中的實驗數據以及文獻的實驗結果一致。

So far, many researchers developed the Cu-based metallic glass with critical size until centimeter-scale. However, known alloy systems are basically limited to Cu–Zr-based alloys and the development of new shape memory BMG composites is essential to broaden the knowledge and to improve the properties of these composites. Very recently, new BMGs have been found in the Cu-Ni-Ti ternary system near the pseudo-binary eutectic (L ⇔ TiCu + TiNi). Fully glassy rods of 1 and 1.5 mm diameter were obtained, which also exhibit good mechanical properties
In this study focused on the calculation of phase diagram (CALPHAD) to predict the metallic glass region. The re-assessment of Cu-Ni-Ti ternary phase diagram have established well by using the parameters from the pieces of literature. After establishing the reasonable Cu-Ni-Ti thermodynamic database to describe each phase, the binary and ternary phase diagram can be plotted. The thermodynamic parameters were also used for predicting the metallic glass regions by combining the metastable phase diagram which suppressed intermetallic compounds (IMCs) phases, liquid miscibility gap, and spinodal curve. The predicted region have consistency with the experimental data and experimental result from the pieces of literature in bulk metallic glass alloys which done in this study.
