應用1981年Valanis及Lee所提議之變形動力學理論，對各種不同溫度及應力狀態下，不同鉛錫比銲材如40Pb-60Sn、90Pb-10Sn、95Pb-5Sn、96.5Pb-3.5Sn、97.5Pb-2.5Sn、98Pb-2Sn的穩態潛變率數據，決定其變形動力學相關之材料參數值，並進而探討變形動力學參數與溫度及Sn/Pb組成比之關係，並建立對應之經驗公式及討論於鉛錫銲材中若增加1%鉛時，變形動力學相關參數之變化率。
應用上述之經驗公式，可補齊90Pb-10Sn及96.5Pb-3.5Sn穩態潛變率/應力/溫度之不完整實驗數據。最後應用98Pb-2Sn之實驗數據來探討鉛錫銲材微結構的轉化(Transformation)程度對變形動力學材料參數以及穩態潛變率之影響。
