Wpływ szybkości nagrzewania podczas spiekania na właściwości mechaniczne spieków Fe40Al w temperaturze pokojowej
Języki publikacji
Abstrakty
The results of a uniaxial compression test of Fe40Al (at. %) sintered powders are presented. Compression yield stress Rc0.2, ultimate strength Rcm, permanent deformation, and true compression strength at the maximum force point were determined. All Fe40Al sinters behaved like a plastic material; they were not brittle, and the sample after the compression test did not fall apart and was barrel-shaped. Observations of the microstructure revealed plastically-deformed grains. The obtained sinters were characterized by very high ultimate compressive strength (ok. 2700÷2800 MPa) and low yield stress (Rc0.2 approx. 280 MPa). This paper presents also XRD analyses, microstructure, and density of Fe40Al sinters.
Podstawowym celem pracy było zbadanie wpływu szybkości nagrzewania podczas spiekania na właściwości mechaniczne spieków Fe40Al. W pracy zaprezentowano wyniki analizy dyfrakcji rentgenowskiej, pomiary gęstości, twardości sposobem Vickersa (HV0,5), a także właściwości wytrzymałościowe uzyskane w próbie ściskania.
