ISO 10275:2007 —拉伸應變硬化指數
ISO 10275 : 2007 詳述了測定平坦金屬材料(典型的像是鋼板和鋼帶)拉伸應變硬化指數的方法,一般稱之為 n 值。
為計算 n 值,測試必須依據 ISO 6892 來執行,搭配使用軸向延伸計產生應力應變曲線。在整個均勻的塑性應變範圍計算 n 值,此範圍通常從均勻的應變硬化區開始,在降服點現象之後,一直持續到抗拉強度被計算出的那一點(Rm)之前。這些計算可經由使用 Bluehill(非精簡版)或 Partner 軟體自動完成。
ISO 10275 測試通常與 ISO 10113(塑性應變比)同時執行。
2630 Series Strain Gauge Extensometers
The 2630-100 series of extensometers offers speed of attachment and ease-of-use. The light-weight, rugged cross-brace design eliminates errors caused by physical distortion, while built-in protection ensures that damage is not caused by over-extension. The low operating-force arms of the extensometer reduce the possibility of knife-edge slippage when testing hard or smooth surfaced materials.
