Abstract
The emission intensity from mechanoluminescence (ML) film (SrAl2O4:Eu2+) on a steel was lower than that on an aluminum alloy. The phenomenon was confirmed by utilizing detachable ML films where two films with identical properties were adhered to testpieces of dissimilar materials. The ML intensity from the one adhered on an Al-Mg-Si alloy testpiece was six times higher than that from the other on a ferric stainless steel testpiece, under the identical tensile testing conditions. Furthermore, the stainless steel testpiece, of which only single side was adhered with an aluminum foil, was prepared, the ML tests were held on both sides with the same detachable ML films. As the result, the intensity from the aluminum side showed more than twice than that from the other side without aluminum. Therefore, it is newly found suppressed ML performance on steel sheet can be avoided with the aluminum insert.
