This　paper　reports　the　interdisciplinary　approach　of　simultaneous　use　of　a　stereological　method,　namely　the　five　parameter　analysis　(FPA)　method　and　the　grain　boundary　character　distribution　(GBCD)　in　cemented　carbides.　There　are　six　major　aspects:　i)　the　background　and　motivations　of　the　interdisciplinary　approach,　ii)　the　principle　of　the　FPA　method,　iii)　orientation　texture　of　boundary　planes　with　specific　misorientations　via　λ(∆g,　n)　mode　in　cemented　carbide,　iv)　orientation　texture　of　habit　planes　regardless　of　misorientations　via　λ(n)　mode　in　cemented　carbide,　v)　application　of　the　FPA　method　to　serial　cemented　carbide　samples　and　vi)　boundary　sort　methods　before　using　the　FPA　method.　The　work　aims　at　presenting　beneficial　reference　for　studying　structural　and　distribution　features　of　special　coincidence　site　lattice　(CSL)　boundaries　in　a　statistical　manner,　and　in　turn　increasing　the　knowledge　about　the　structure-property　relationship　in　cemented　carbides.　©　2022　Authors.　All　rights　reserved.
