Registration of melting and crystallization process of MCMgLi8Ca5 alloy with use of ATND method
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 2
Abstract
Among lightweight metal alloys, magnesium is the lightest structural material with density of 1.74 g/cm3, having many attractive physical and mechanical properties combined with processing advantages. Therefore, it represents very attractive material for large amount of applications starting from automotive industry as the main user, up to other industry fields like sports, robotic electronics, armaments, and textile ones, or production of audio-video equipment. Furthermore, addition of lithium, that has density of 0,53 g/cm3, reduces density of the resulting Mg-Li alloys to the same level as polymeric materials. On metallic matrix of magnesium alloys with lithium are also manufactured composites reinforced with e.g. ceramic fiber, which are used as a lightweight and resistant structure materials. Therefore, Mg-Li alloys become an alternative material assuring low density, improved ductility and corrosion resistance. The paper presents an attempt of implementation of the ATND method to monitoring of crystallization process of MCMgLi8Ca5 alloys. Investigated magnesium alloys were produced in the Foundry Research Institute. Registration of melting and crystallization processes was made with use of the ATND method. Results of the preliminary tests are shown in a graphical form.
