项目摘要
Structure and tensile plastic deformation behaviors of electrodeposited nanocrystalline Ni-W alloys have been examined. By controlling the surface roughness of the Cu-substrate, the Ni-W alloys with mesoscale Ni-segregated network structure has been prepared. Tensile strengths of the Ni-14~18 at. % W alloys were attained to about 3 GPa with the total strains of 3~5 % containing the large plastic strain of about 0.5~3 %. These results have suggested that the Ni-segregated mesoscale structure is effective for improvement of the tensile plasticity. Work hardening was also observed. By using the FIB-milling technique, local grain growth was observed near the fractured surface. It may be suggested that the local grain growth is occurred during local plastic deformation, resulting the work hardening according to the inverse Hall-Petch strengthening law.
通过控制铜基体的表面粗糙度,研究了电沉积纳米晶镍钨合金的结构和拉伸塑性变形行为,制备了具有细观镍偏析网络结构的镍钨合金。 14~18at.%W合金达到约3GPa,总应变为3~5%,其中包含约0.5~3的大塑性应变。这些结果表明,通过使用FIB铣削技术,还可以观察到Ni偏析的介观结构对于断裂表面附近的局部晶粒生长是有效的。局部塑性变形过程中发生局部晶粒长大,根据逆 Hall-Petch 强化定律产生加工硬化。
