100噸熱滾壓機

100-T Hot Roller

本儀器為100頓冷熱滾壓機，雙滾輪系統，其滾輪直徑與長度分別為140 mm與220 mm。利用冷軋延或熱軋延可以使材料加工，在軋延的過程中，被軋延的材料在經由兩個旋轉方向相反滾輪間產生塑性變形之後，可以獲得所需要之板材或者線材。同時，利用軋延技術亦可使被軋延材料產生微結構變化達到晶粒細化之料果，而得到物理及機械性質較佳的材料。利用滾壓機進行累積滾壓接合(accumulative roll bonding, ARB)可應用於各種合金之奈米細晶化及非晶質化機構轉變的研究，特別是奈米細晶至一臨界大小，會立即轉變至非晶質材料。

The stacked sample was rolled by a 100-ton (HF 200×200) cold and hot rolling machine. The roller diameter is 140 mm and the roller length is 220 mm. The samples can be worked between two rollers to fabricate the plate or sheet via the cold and hot rolling technique. The physical and mechanical properties of the rolled samples will be improved due to grain refinement. Moreover, the accumulative roll bonding (ARB) technique can be applied to the investigation on the gradual nanocrystallization and amorphization mechanisms in various alloys. The sudden transformation from nanocrystalline to amorphous state near a critical nano size would occur.
