Ni-W合金是一种很有前途的高温结构材料。然而，它们在拉伸试验下没有显示出塑性变形。为了提高Ni-W合金的拉伸韧性，在氨基磺酸盐镀液中加入糖精钠、2-丁炔-1，4-二醇和烯丙基磺酸钠等添加剂，制备了Ni-W纳米晶合金。它们的取向、微观结构和拉伸行为存在显著差异。特别地，从含有糖精钠的氨基磺酸盐浴沉积的样品表现出更强的（200）织构和约5.0%的良好拉伸延展性。这些实验表明，织构的控制是重要的，以提高电沉积块体纳米晶Ni-W合金的拉伸塑性。(C)2013爱思唯尔有限公司版权所有。
Ni-W alloys are promising materials for high temperature and structural applications. However, they show no plastic deformation under tensile tests. We electrodeposited bulk nanocrystalline Ni-W alloys from sulfamate baths that contained different additives, such as saccharin sodium, 2-butyne-1,4-diol, and sodium allylsulfonate, to improve the tensile ductility. Their orientation, microstructure and tensile behavior significantly differed. In particular, the sample deposited from a sulfamate bath that contained saccharin sodium exhibited a stronger (200) texture and good tensile ductility of approximately 5.0%. These experiments indicate that control of the texture is important to enhance the tensile ductility of electrodeposited bulk nanocrystalline Ni-W alloys. (C) 2013 Elsevier B.V. All rights reserved.
