The effects of pouring temperature, short electromagnetic stirring with low strength and then soaking treatment on the microstructure of AlSi7Mg alloy were investigated. The results show that if AlSi7Mg alloy is poured at 630 or 650℃ and meanwhile stirred by an electromagnetic field at a low power f...

The formation process of copper type rolling texture in f.c.c. metals was simulated based on a deformation model considering internal reaction stresses induced by the neighboring matrix as well as external shear stress induced by rollers. It is indicated that the external shear stress will reduce th...

The nondendritic semi-solid slurry preparation of 60Si2Mn spring steel has been studied in this paper. The experiments have shown that when stirred for 2 min on the test condition, the semi-solid slurry with 50%~60% fraction solid and spherical primary austenitic grains in the size of 100~300 μm can...

The image stress of straight screw dislocations parallel to the medium surface covered by thin heterogeneous films was analyzed and deduced, in order to calculate the image shear stress. The relationship between image stress and distance from the screw dislocation to the interface of pure aluminum a...
