由显微镜拍摄的照片显示了汉普顿弗吉尼亚州NASA Langley研究中心的工程师们所取得的早期努力的结果之一,即在开发用于亚音速和超音速飞机结构材料的超低密度合金中喷射沉积的利用。照片(在本页中表示的)是由材料研究工程师和金相学家Robert Edahl Jr.拍摄。 照片显示了由铜、锰、镁、硅、钙、钒和锆组成的喷射成形铝合金。为了获得最佳元素成分,NASA研究小组用几种工艺变量进
A photograph taken by the microscope shows one of the early efforts of engineers at the NASA Langley Research Center in Hampton, Virginia, to develop spray deposition in ultra-low-density alloys for subsonic and supersonic aircraft structural materials The use of. The photograph (represented on this page) was taken by material research engineer and metallographer Robert Edahl Jr. The photograph shows a spray-formed aluminum alloy consisting of copper, manganese, magnesium, silicon, calcium, vanadium and zirconium. To get the best elemental composition, the NASA team used several process variables
