【Abstract】 The influence of rotating electromagnetic field on the structure of ZA 27 alloy has been studied by means of electromagnetic stirring. An approach to the rheological structure forming mechanism has been made. In addition, the influence of the variation of the technological conditions such as alternating the rotating direction of electromagnetic field and adding alloy elements to ZA 27 alloy on the rheological structure of ZA 27 alloy has been experimentally studied.更多还原
