The phase transformation in as-deposited, metastable ΞΊand Ξ³-alumina coatings on cutting inserts has been studied by a combination of X-ray diffraction, scanning electron microscopy and cathodoluminescence. In the case of ΞΊ-alumina, mechanical forces during metal cutting lower the transformation temp
