Formation, Thermal Stability and Mechanical Properties of Cu-Zr and Cu-Hf Binary Glassy Alloy Rods
Glassy alloy rods with diameters up to 1.5mm exhibiting a large supercooled liquid region before crystallization and high mechanical strength were formed in Cu-Zr and Cu-Hf binary alloy systems by the copper mold casting method. The large supercooled liquid region exceeding 40K was obtained in the composition range of 30 to 70 at%Zr and 35 to 60 at%Hf. The largest value of the supercooled liqui...
متن کاملEffect of Cu Addition on Soft Magnetic Properties of Fe–Zr–Si Amorphous Alloy
The effect of Cu addition on the soft magnetic properties of FeZrSi amorphous alloy was investigated by X-ray analysis, TEM observation, and B-H curve tracer. As a melt-spun amorphous ribbon sample was annealed above the crystallization onset temperature, very fine ¡-Fe particles smaller than 315 nm were precipitated and uniformly distributed in an amorphous matrix. Cu addition to FeZrSi am...
متن کامل[Mechanical studies on casting titanium alloy denture base].
The mechanical properties of the Akers type clasp, bar and frame made by the newly developed Ti-20Cr-0.2Si alloy were studied in order to obtain the indices for designing the cast partial denture base. In the case of the clasp, the bending strength of the Ti-20Cr-0.2Si alloy and pure Ti was lower than that of the Co-Cr alloy. The Ti-20Cr-0.2Si alloy and pure Ti may have the same retentive force...
متن کاملHigh-Temperature Stability and Grain Boundary Complexion Formation in a Nanocrystalline Cu-Zr Alloy
Nanocrystalline Cu-3 at.% Zr powders with 20 nm average grain size were created with mechanical alloying and their thermal stability was studied from 550–950 C. Annealing drove Zr segregation to the grain boundaries, which led to the formation of amorphous intergranular complexions at higher temperatures. Grain growth was retarded significantly, with 1 week of annealing at 950 C, or 98% of the ...
متن کاملEnhancement of Plasticity of Highly Density-Fluctuated Cu-Zr Amorphous Alloy
This study explores the plastic deformability of highly density-fluctuated states due to the different thermal quenching process of the binary amorphous metals, Zr67Cu33, with embedded nanocrystals, Zr2Cu. To know the effect of local structural fluctuation, we prepare 5 computational models with Zr2Cu-nanocrystals that undergo rapid heat up and cool down. The region of nanocrystals is correspon...
