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。
