Under the high frequency vibrating action, the crystal grain formed on the surface of the crystal nucleus eradiation equipment would be broken and peeled off, thereby ejected to zinc molten pool continuously and served as crystal nucleus source of equiaxed grain during solidification.

结果表明，当一种带有冷却结构且进行高频振动的晶核发射器插入锌液内时，锌液在晶核发射器表面迅速形核且长大，在高频振动作用下表面形成的晶粒将被折断剥离，从而连续不断地弹射到锌液中，成为凝固过程中形成大量等轴晶的晶核来源；采用带有水冷和气冷结构的晶核发射器对锌液进行振动激发形核处理后，锌凝固组织中的等轴晶率可分别提高到65%和80%。

The results show that the microstructures of these three kinds of coating are different from those of the matrix (20 steel). The wear resistance of the flame spray coating is 4. 9 times that of the matrix. This is caused by the existance of hard noncrystal microparticals. The wear resistance of the coating by flame spray welding is 6. 3 times that of the matrix. The reason is that the fine crystal grains can be formed and the solution strengthening, dispersion hardening can be induced by these alloy elements. The resistance of the laser remelt coating is 8. 8 times that of the matrix. This is due to the solution strengthening, dispersion hardening and the existence of very hard dendritic crystal, eutectic and martensite in the microstructure.

作者指出，喷涂层由于层内有一定数量高硬度的合金非晶质点存在，其耐磨性是钢基体的4.9倍；喷熔层内合金晶化产生的晶粒细小，合金元素能起固溶强化作用，也能生成化合物产生弥散硬化作用，故此耐磨性是钢基体的6.3倍；激光涂敷层除所含合金元素产生的固溶强化和弥散硬化作用外，表层组织为高硬度的枝晶+共晶和马氏体，故其耐磨性是钢基体的8.8倍。

After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.453.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

From the microstruture observation, this dilatancy produced is clearly associated with a change from crystal plasticity plus minor cataclasis (formation of closed intragranular cracks) at high pressure (20MPa) to crystal plasticity plus significant cataclasis (involving axial cracking, intragranular cracking, crack opening and shearing) below 10MPa.

This paper deals with and summarizes the research and importance of ductile shear zones and presents the future direction and aim for the research of the ductile shear zones around the world. Four aspects of studies of the ductile shear zones have been proposed in this paper as follows:(1) The stress environment including the mineral assemblages, deformation, stress-shearing parameters;(2) The major element sequence and activation under condition of stress;(3) The variations of trace elements and REE, their transportation distributions under strong natural deformation as well as variations of mineral crystal parameters, which can also control the element changes during the ductile deformation;(4) The relationship between element migrations, activation and stress, which will present the new evidences for the studies of dynamic diagenesis and mineralization as well as the studies of evolution of ductile shear zones developed in middle and low levels.(5) The analysis of elements and isotopes in mylonites on the micro-scale are crucial for the understanding of component migrations during the mylonization.
