Slitiny na bázi hořčíku pro aplikace v automobilovém průmyslu

Abstract

Magnesium alloys are still idle in technical applications because of their properties. Magnesium is very light. Its weight is about one third less than the weight of aluminum and it is the third most frequented structural metal. However its preparation and processing can be problematical because magnesium has high affinity to oxygen. It causes intensive burning. The usage of magnesium alloys took more importance and it is the most used alloy in automotive field sofar. Nowadays a vast majority of casting are not sufficient for the applications that need high security and reliability. To reach higher mechanical properties a forging technology can be used. High demands of properties are made on components for car industry or components used in outer space.
