Effects of Main factors as corrosive chemicals, corrosion pit size and enrichment concentration are quantitatively analyzed according to useful data and actual samples of blades and operation experience. Based on these detailed studies, blades have been improved to have sufficient integrity under practical chemical enrichment zone.}, pages = {72--80}, title = {機械駆動用蒸気タービン動翼の腐食疲労現象と寿命向上に関する研究(第1報:腐食性物質の濃縮域と腐食疲労に関する考察)}, volume = {35}, year = {2007}, yomi = {ツカモト, ヒロシ} }
