In the fatigue test, the specimen was forced through the impact and the residual stress of the specimen began to accumulate with the increase of plastic deformation. The stress equivalent magnetic field theory [33–36] shows that the effect of stress is equivalent to the external magnetic field...
A variety of methods for producing MMCs on the industrial scale have been developed, including powder metallurgy (PM) [12], high-energy milling [13], and severe plastic deformation [14], which are considered to be a forms of solid state processing. The major critical problems facing these ...
