                取樣位置要在斷口且參差不齊,直徑達不到3MM片,怎麽做透射?

                2016-10-25技術資料

                透射樣制樣達不到直徑3MM怎麽做透射啊?

                看沖擊試樣斷口處基體和第二相的變形特征的,所以取樣位置要在斷口,而斷口參差▆不齊,做不成一個直徑3MM的圓片,該怎麽做呢??是不是我想錯了呢???
                在離開斷口一段距離位置取樣即可
                ?
                謝謝,你之前這樣做過≡嗎?
                不在斷口取樣,而在離開斷口一段距離位置取樣看到的不準確吧???

                謝謝,你之前這▓樣做過嗎?
                沒問題
