J. Cent. South Univ. (2021) 28: 1170-1182 DOI: https://doi.org/10.1007/s11771-021-4688-8 Fe-Zn supersaturated solid solution prepared by mechanical alloying and laser sintering to accelerate.... In this work, mechanical alloying (MA) was used to prepare Fe-Zn powder with supersaturated solid solution. MA significantly decreased the lamellar spacing between particles, thus reducing the diffusion......
alloying; supersaturated solid solution; Cu-C system 1 Introduction Many works have been carried out to check the possibility of replacing silver by copper in electronic contacts application, in which...)) and mechanical twins (Fig.6(c)) coexist in one specimen. It can be inferred that the microstructure is inhomogeneous through the specimen. 4 Discussion 4.1 Supersaturated solid solution of carbon......
