Název v původním jazyce

Highly Thermally Stable Light-Weight Al Based Alloys Prepared by Centrifugal Atomization and Powder Compaction

Popis výsledku v původním jazyce

Combination of centrifugal melt spraying and hot die-forging of a rapidly solidified semi-product was presented as a promising and inexpensive method for processing of aluminium based alloys of unconventional chemical compositions, e.g., those containinghigh concentrations of thermally stabilizing transition metals. In our study, the use of this processing method is illustrated for the Al-23Si-8Fe-5Mn (wt. %) alloy. Structure was examined by LM, SEM, EDS and XRD. Mechanical properties were determined by hardness and compressive tests. Thermal stability was assessed by measuring the hardness development during long-term annealing, elevated temperature compressive tests and creep tests. The research showed that the investigated alloy exhibits excellentthermal stability as compared with commercial thermally stable aluminium alloys currently used in automotive and aerospace industry.
