本文利用和攪拌摩擦銲接(FSW)原理相同的攪拌摩擦製程(FSP)來進行研究，所謂入熱條件指的是製程時的轉速及銲速，本研究以相同轉速和不同銲速的條件來觀察鋁合金5083板材的機械性能表現以及金相組織和殘留應力分佈，使用FEM模擬製程時的溫度是否可以達到適當的製程溫度，並實際量測溫度場來驗證模擬的正確性。
經觀察及量測統整後，發現FSP在攪拌頭附近的暫態溫度分佈與轉速和塑性流動有關；而塑性流動大小則和板材溫度變化的速度有關，在塑性流動大(銲速較慢)時可以得到較佳的銲接品質，而由轉速產生的良好製程溫度應介於一次和二次再結晶溫度之間。在往後進行FSW時可以使用FEM法將實際的攪拌頭模型建立，計算出適當施予轉速的範圍，而在本文中的使用的材料和攪拌頭結果顯示在適當的轉速下，銲速(mm/min)與轉速(rpm)比不宜大於0.43。
研究流程可分為四個步驟：
(1) 決定攪拌摩擦製程各參數，包括攪拌頭形狀、板材規格、進刀量、傾斜角、轉速及銲速。
(2) 測量製程中下壓力、溫度分佈及製程後板材殘留應力並觀察金相組織。
(3) 對製程後板材進行靜態拉伸試驗以及疲勞裂縫進展試驗評估。
(4) 以FEM模擬板材在不同入熱條件時的溫度分佈和各測量數據做統整並預估最佳入熱條件。

This article is based on the Friction Stir Processing (FSP) which have the same principle as Friction Stir Welding (FSW) theory to make a research. The idea of Heat Input Condition means the rotational speed and weld speed during the processing experiment. So the article used the same rotational speed but the different weld speeds to observe mechanical property, metallographic organization and residual stresses distribution on the aluminum 5083 alloy materials. To see if the temperature could reach the appropriate processing temperature when using Finite Element Method (FEM) and to real measure temperature field for test the imitative testing accuracy.
After observing and measuring, it found that near by Friction Stir Processing (FSP) rotating tool transient temperature distribution and rotational speed have relations with plastic flow, otherwise the plastic flow’s proportion connect with temperature changing speed of aluminum alloys. The bigger (slower weld speed) in plastic flow, the better quality you can get. A good processing temperature which produces from rotational speed should situated between first and second times recrystallization temperature. In the future to do Friction Stir Welding (FSW) can use Finite Element Method (FEM) to build up reality weld head model and count appropriate rotational speed range. The result show that below the appropriate rotational speed, the weld speed (mm/min) divide by rotational speed should not over than 0.43.
Research process can be separate by four parts:
1. Decided Friction Stir Processing (FSP) processes parameters, included the shape of welding head, specification of aluminum alloy plate material, feed rate, inclination angle, rotational speed, and weld speed.
2. To measure pressure during processing, temperature distribution, residual stresses distribution on the aluminum alloy material, and to observe metallographic organization.
3. To evaluate the aluminum alloy plate material after texting by Tension Testing and fatigue crack.
4. Use Finite Element Method (FEM) to imitate different temperature, thermal stress distribution and measure date in heat input then not only make a rational connection but also estimate the best heat input condition.
