a significant influence on the formation of thixotropic microstructures during partial remelting. Coalescence and Ostwald ripening are operative in the semi-solid mixture for both compression and ECAE... remelting depends mainly on the amount of stored energy. The more the amount of stored energy, the smaller the recrystallized grain size. By comparing Fig.2(a) with Fig.3(a), it can be found that the rate......
and important especially in the automotive industry, and also in comparison to laser technologies. This paper deals with different EB surface technologies, for example hardening,remelting, surface alloying......
of solidification cooling rates(from 0.05 to 106 K·s-1) was achieved using various solidification processes, including conventional casting, laser remelting, and melt spinning. The size and distribution......
and compactness in electroslag remelting(ESR) ingots were studied,and the mechanism of ultrasonic assistance was analyzed in cold experiments. In the results,silicon,manganese and chromium......
