本研究主要藉由不同 In 含量的添加，探討 In 含量對 Sn-Ag-Cu-In-Zn-Bi 合金的 機械性質，並改變拉伸速率及溫度，進而分析其常溫與高溫下的機械性質。

.
經由 DSC 熔點測試後的曲線圖可得知隨 In 含量增加，熱波谷有向左邊移動且面 積有變小的趨勢，進而得知添加的 In 元素是可降低合金熔點溫度。2.利用 EDS 與 XRD 成分分析得知合金由 Sn、Ag、Cu、In、Zn、Bi 等元素所組成，
並由金相圖發現當 In 含量增加，則晶粒逐漸變大，故證實添加過量之 In 元素無法 有效細化晶粒之功用。
3.實驗的合金由維氏硬度測試結果得知，當 In 元素含量愈多，則硬度數值愈高。其中 以 In 含量為 2.0wt%的硬度值 15.61Hv 最小，以 In 含量為 8.0wt%的 17.64Hv 為最 大，說明 In 元素的添加會提高合金的維氏硬度值。
4. 實驗中合金的最大平均應力會因拉伸速率減慢與測試溫度升高而降低，並且隨著 In 含量增加其平均應力值亦增加。在室溫環境下，當拉伸速率為 1×10-3mm/sec 時，
In 含 量 為 8.0wt% 時 ， 試 片 的 最 大 平 均 應 力 為 42.86MPa ， 當 拉 伸 速 率 降 至 1×10-4mm/sec 時，其平均應力下降至 35.66MPa。
