摘要: 
This thesis evaluated Young's modulus of bulky lead zirconate titanate (PZT) by micro tensile test, nanoindentation test and analytical calculation. First, bulky PZT was formed in dog bone shape using micro-milling and was tested in micro tensile test. Second, bulky PZT was measured by nanoindetation test. Finally, bulky PZT was bonded on copper substrates and shaped in the form of fixed-fixed beam. Resonant frequencies of fixed-fixed beam were evaluated and used to calculate Young's modulus in analytical model. Average Young's modulus 90.5GPa 92.73GPa and 75.6GPa were investigated by micro tensile test, by nanoindetation test and by analytical calculation.

本論文運用了三種不同方法量測PZT塊材楊氏係數,第一種方式為利用微拉伸試驗法測得PZT塊材之楊氏係數;第二種方式為奈米壓痕測得PZT塊材之楊氏係數;第三種方式為共振頻率法帶入數學模型求得楊氏係數。
由實驗結果得知,利用微拉伸試驗法求得之楊氏係數平均值為90.5 GPa、奈米壓痕法所測得三點楊氏係數平均值為92.73 GPa、共振頻率法測得之楊氏係數為75.6 GPa。
實驗證明微拉伸試驗法與奈米壓痕法皆可適用於壓電材料之楊氏係數量測,兩者之實驗數值相當接近,可提供另一種量測壓電材料之楊氏係數的方法。
