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.
