Subject aims expressed by acquired skills and competences

Studenti se po absolvování předmětu mohou orientovat mezi různými kovovými a nekovovými materiály, přicházejícími v úvahu při konstrukci a údržbě letecké techniky. Jsou to oceli, zejména o ultravysoké pevnosti, kde kromě chemického složení získají představu o tepelném zpracování, o svařování a o trhu těchto ocelí. Další kovové materiály jsou hliníkové slitiny, kde kromě chemického složení, jsou rovněž definovány podmínky tepelného zpracování, konečné hodonoty pevnosti a tažnosti a odolnosti proti korozní únavě a korozním praskání pod napětím. Další materiály jsou titanové slitiny hořčíkové slitiny a slitiny mědi. Základní znalosti o technické keramice, kompozitních materiálech a plastech jsou demonstrovány.
