a principle of the magnetic circle designing of rotary magnetic method used in making semisolid slurry with non dendritic structure is analysed by the semi lumped factor method.
通过磁路半集总参数分析,提出了用旋转永磁体法制备非枝晶组织半固态浆料的磁路设计原则。
the results show that the magnetic density and the lorentz force of semisolid slurry increased with the enhancement of current strength at the same current frequency;
结果表明:在相同频率下,半固态浆料内的磁感应强度、电磁力的大小随电流强度的增加呈线性增加的关系;
the microstructure evolution of az91d magnesium alloy semisolid slurry in the sima process was investigated, and the influencing factors on spherical microstructure evolution were analyzed.
研究了大体积az91d镁合金在sima法制备半固态浆料过程中组织的演变规律,并对半固态组织球状化演变的影响因素进行了分析。
