Evaluation of true interlamellar spacing from microstructural observations [PDF]
, 2008 A method for evaluating true interlamellar spacing from micrographs is proposed for a multidomained lamellar structure. The microstructure of these materials is assumed to be composed of many domains with the lamellae aligned roughly parallel to each ...
