Meanwhile, the surface layer gets fine crystal grain with dispersive and homogeneous distribution of WC grains and Co binder from rapid melting and resolidification during HIPIB irradiation. Minimizing the mean free path in Co binder by decreasing the WC grain size leads to an increase in resistance to plastic deformation in the binder.

HIPIB强烈非平衡作用下的重熔和再结晶使WC晶粒细化且分布更均匀，同时，表层析出弥散分布的Co_3w_9C_4相，使Co粘结相产生强化，导致Co粘结相的平均自由程降低，从而增强了Co粘结相抵抗塑性变形的能力，提高了辐照硬质合金的耐磨性能。

The formation of secondary phase in the non-equilibrium peritectic reaction was observed by precise transmission electron microscopy analysis. The microstructural evolution and phase selection regularities under different solidification velocities were constructed from the laser resolidification experiments. A new phenomenon involving two-phase coupled growth was firstly detected in the rapidly solidified Ti-Al peritectic alloy. The Ti-45Al-2Cr-2Nb alloy with fully lamellar structure ( a 2+ g ) was taken as an object to investigate the possible preparation of bulky metastable g phase materials based on both adjusting the competing nucleation relation and changing the growth kinetics condition.

首先通过过冷合金微观组织分析界定了各包晶合金熔体中各竞争相以初生相出现的过冷度区间；结合高温区的相图计算，从各相形核孕育时间角度揭示了过冷熔体中亚稳相与稳定相的竞争形核关系；通过精细微观组织分析，阐明了远离平衡时包晶反应中次生相的形成机理；在激光重凝快速凝固实验中建立了不同凝固速度下合金的组织与相形成规律，并对包晶合金中两相共生生长行为进行了深入分析；最后选取初生相为 a 的全层片 Ti-45Al-2Cr-2Nb 合金，从调整各相竞争形核关系和改变晶体生长动力学条件两个方面探索了块状亚稳 g 相材料的制备和控制。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
