Course detail

Metallurgy of Nonferrous Metals

FSI-PLNAcad. year: 2017/2018

The course gives an overview of non-ferous cast alloys. Emphasis is given namely on aluminium a magnesium alloys, copper, zink and other alloys are mentioned briefly too. Types of alloys, their composition and main properties are mentioned. Crystallization and metallurgical processing are discussed in details. They are introduced types of melting furnaces suitable for different alloys. Metalurgicall defects, their identification and possibilities of reparing are commented.
