摘要
Abstract
The definition,source,hazard and problem-solving method of casting defects in aeroengine single-crystal blades and vanes were summarized.In order to provide suggestion to problem-solving methods,the definition and hazard of low angle grain boundary,isolated defects,recrystallizated grain,striation,freckle,microporosity,inclusion were introduced and the formation mechanism and possible source were analyzed,individually.关键词
