摘要
本研究主要目的在於探討束縛燒結之緻密驅動力。以等溫燒結和非等溫燒結的方式透過兩種不同實驗設施:1.雷射量測系統2. 熱機械分析儀分別取得試片燒結過後之緻密性質、束縛燒結應力與自由燒結驅動力。
實驗結果發現:1.束縛燒結的緻密速率要緩於自由燒結的緻密速率,但不降低緻密程度。2.束縛燒結並無顯著改變自由燒結的燒結控制機制。3.因束縛燒結而所產生的平面張應力數量級足以與X-Y軸向的自由燒結驅動力相抵銷,以致大大減少了整體的平均燒結驅動力,是降低束縛燒結緻密速率的主要因素。4.以非等溫燒結的方式,在升溫速率越慢的燒結條件下,自由燒結與束縛燒結兩者間的燒結緻密曲線差異便越小,且在同溫度下較其他升溫速率快達到燒結緻密。
