Mechanical alloying (MA), a solid-state powder processing method, is a "far from equilibrium" synthesis technique which allows development of novel crystal structures and microstructures, leading to enhanced physical and mechanical properties. The ability to synthesize a variety of alloy phases incl...

Application of Acoustic Emission to the Study on Cathodic Polarization and SCC for High Strength Steels

ZHU Ziyong V.A.Marichev Institute of Physical Chemistry of the Academy of Sciences of the USSR , Moscow , 117171 , USSR.

材料科学技术（英文）

The ambiguous effect of cathodic polarization on SCC of two high strength steels in 0.1 M Na_2HPO_4 and 0.1 M NaNO_3 has been investigated by means of meas- uring electric resistance(R)and recording acoustic emis- sion(AE)signals simultaneously.Results showed that AE sensitivity strongly depends on ...
