图1 D等离子体辐照在表面取向为[111]、[110]和[001]的W晶粒上引起的表面起泡现象[16]

Fig.1 Surface (a, c, e) and crosss-ection (b, d, f) morphologies of surface blistering of D plasma exposed W with surface normal directions close to [111] (a, b), [110] (c, d), and [001] (e, f) directions, respectively[16] (Red arrows in Fig.1d show two blisters caused by the gas pressure inside the cavities beneath the surface; A blue arrow in Fig.1d shows a large cavity along the grain boundary; Blue arrows in Fig.1f show that there were also cavities beneath the surface, but these cavities did not induce any obvious blisters on the surface at all)
