, 30(2): 93-101. [9] Mamadou F, Belem T, Samb S, et al. Experimental characterization of the stress–strain behaviour of cemented paste backfill in compression[J]. Journal of Materials Science, 2007......
particles form cluster morphology [29]. Once the cluster area reaches a specific level, the stress concentration causes the alloys to fracture quite readily during the deformation process. The fracture......

the extent of stress shielding [6-7]. Even though TiNi alloys share a relatively excellent bioactivity, they can not likely form a direct chemical bonding with bones, thus surface modification is critical......
] or oxidative stress via the generation of reactive oxygen species (ROS) on crystal surfaces of some nanoparticles (e.g., silica (SiO2), 45S5 bioglass) [31]. S. mutans in this study was killed not only by Ag......

洞.裂纹的形成主要分为两种,空穴裂纹以及热应力裂纹(Thermal stress crack, TSC).空穴裂纹的产生是因为熔池中的气泡在脱离熔池的时候在熔池表面形成孔洞,经过多次操作循环后,这些由气泡破裂形成的材料空穴最终发展成裂缝,如图10(a)中裂纹即为典型的空穴裂纹.空穴裂纹主要产生在阳极.热应力裂纹是触头材料反复受到热胀冷缩的作用下形成的.当较大电弧能量作用于触头表面时,材料由于受热膨......
