krzem - Opis:
- Available technical literature includes a number of reports on harmful effects connected with elevated content of iron in aluminium-silicon alloys but in case of pressure castings, alloys containing up to 2% Fe can be used. This follows from lesser susceptibility of such alloys to sticking to surfaces of metal moulds. One effect of iron presence in aluminium-silicon alloys is precipitation of iron-rich intermetallic phases. In the study reported in this paper it has been found that in a multicomponent aluminium-silicon alloy, the indentation hardness (HIT) and the elastic indentation modulus (EIT) of intermetallic phases occurring in the form of polyhedrons and/or their conglomerates, rich in aluminium, iron, silicon, manganese, and chromium, containing also copper, nickel, and vanadium, are higher than those measured for silicon crystals. This feature can be used to intentional modelling microstructure of mechanical parts which are expected to show high resistance to abrasive wear.
