Influence of aging on microstructure and hardness of lead-free solder alloys
Purpose: The purpose of this paper is to carry out a study of the evolution of the microstructure and the microhardness of Sn-Cu-Ag alloys from as-cast condition and under artificial isothermal aging at different temperatures ...
Microstructural Evolution of Cold-Deformed and Isothermally Treated ZA27 Alloys
(Universidade Federal de São Carlos, 2021-06)
Pure ZA27 alloys and ZA27 alloys with Cu and Mg additions were cast and deformed by compression. Samples of both alloys were heat treated at 460°C after deformation and the evolution of the microstructure as a function of ...
Magnetic structure of FexCu100-x magnetoresistive alloys produced by mechanical alloying
FexCul00-x magnetoresistive alloys were produced by mechanical alloying. X-ray diffraction shows fcc structure. The room-temperature Mössbauer spectra evolves from an asymmetrical doublet below x = 25%, to a broad magnetic ...
Giant magnetoresistive properties of FexAu100-x alloys produced by mechanical alloying
(Elsevier Science, 2001-01)
The FexAu100-x alloys were produced for the first time by mechanical alloying. Resistance of samples with iron concentrations of x = 15, 20, 25, and 30 at% were measured at 77 K under an applied field of 14 kOe. A maximum ...
Effects of Zr on the amorphization of Cu-Ni-Zr alloys prepared by mechanical alloying
(Elsevier Science SA, 2018-10-15)
This work presents the effects of high energy milling with different Ni and Zr ratios on the amorphization of ternary Cu-Ni-Zr alloys (initially, Cu-43Ni-7Zr, Cu-12Ni-31Zr, Cu-33Ni-7Zr, and Cu-12Ni-23Zr; and later, ...

Corrosion behavior of a β CuAlBe shape memory alloy containing stress induced martensite
(Elsevier Science, 2019-02)
The corrosion behavior of a β CuAlBe shape memory alloy containing stress-induced martensite was analyzed after 60 days of immersion in a 3.5% NaCl solution. The stress-induced martensite was retained in the sample after ...
Non-alloy/alloy transitions in the Sn/Cu(001) system: An STM, LEED and DFT study
(Elsevier Science, 2017-11-15)
We show that surface alloying during growth of Sn on Cu(001) is inhibited at temperatures below 170 K. We have studied the non-alloying surface structures that are formed starting from low Sn coverage up to 0.65 ML, finding ...
