Study on High Temperature Mechanical Properties and Deformation Mode of Nb-1Zr Alloy AITranslate
Abstract AITranslate
Tensile strength, yield strength, elongation and reduction of area of the Nb-1 Zr alloy at 1 000~1 800 ℃ were tested, and the fracture morphology after unidirectional tensile test was observed.The results show that with the increase of temperature, the tensile strength and yield strength of Nb-1 Zr alloy at high temperature decrease from fast to slowly, and the two gradually approach.The elongation is almost unchanged at 1 000~1 200 ℃,but it increases rapidly with the increase of temperature above 1 200 ℃.The reduction of area does not change much within the test temperature range.The major deformation modes of Nb-1 Zr alloy are dislocation slipping at 1 000~1 200 ℃ and grain-boundary sliding at 1 400~1 800 ℃.There are two kinds of second-phase particles in Nb-1 Zr alloy: Zirconia particles mainly play the role of dispersion strengthening, while zirconium carbide particles mainly play the role of precipitation strengthening.
