Glass-crystalline Phase Constitution Evolution and the effect on Mechanical Properties of Rapidly Solidified Zr-based Alloy
The solidified microstructures of Zr50Cu40Al10, Zr49Cu44Al7, and Zr49Cu46Al5 alloys were studied by rapid solidified technique, and the phase constitution evolution effect on their mechanical properties were explored. The analysis of solidified microstructures revealed that the Zr50Cu40Al10 alloy formed a fully amorphous structure. In contrast, the Zr49Cu44Al7 alloy exhibited an amorphous matrix with spherical B2-ZrCu primary phase particles and B19’-ZrCu phase, while the Zr49Cu46Al5 alloy consisted of an amorphous matrix, B19’-ZrCu primary phase, and rod-like B19’-ZrCu phase. For the Zr49Cu51-xAlx(x=5,7) alloys, both primary phases were homogeneously dispersed throughout the microstructure. The mechanical properties of the alloys were compared with the Zr50Cu40Al10 alloy demonstrating a tensile strength of 410 MPa and a compressive strength of 1608 MPa, exhibiting the largest tensile-compressive asymmetry. The Zr49Cu44Al7 alloy achieved the highest compressive strength at 1865 MPa and the highest yield strength at 1596 MPa. Meanwhile, the Zr49Cu46Al5 alloy exhibited the highest tensile strength at 1395 MPa. Nanoindentation tests indicated that in the Zr50Cu40Al10 alloy, the hardness and elastic modulus increased progressively from the edge to the center of the specimen. For the Zr49Cu51-xAlx(x=5,7) alloys, the solidified microstructures composed of an amorphous matrix and endogenous crystalline phases exhibited higher hardness compared to fully amorphous or crystalline phases. The elastic modulus, however, varied depending on the type of primary phase present.
