镍基耐蚀合金高温加工特性的研究于满1,2,刘明忠1,李京社1,王黎辉1,唐海燕1,包耀宗3(1.北京市新兴铸管集团有限公司2.北京市北京科技大学3.钢铁研究总院 结构材料研究所,北京 10081)摘 要:采用Thermomacmaster-Z热模拟试验机和TEM研究了G3,G3-Z和825镍基耐蚀合金1030℃~1350℃,应变量(ε)0~0.8,变形速率5s-1,25s-1的应力-应变曲线和温度对合金变形抗力和断面收缩率的影响.结果表明,随着温度的升高,合金的变形抗力及其最大值降低,断面收缩率先上升后下降.8......
Modeling of Fracture Toughness of Electroless Nickel (EN) Coatings K. Zangeneh1,F.Ashrafizadeh3,S.M. Monir-vaghefi3 (1.Department Of Engineering, Islamic Azad University-Saveh Branch, Saveh 39187...:In the present reserch, a model has been proposed for estimate fracture toughness of Nickel-phosphorus (EN)layers. For this purpose, high phosphorus (9%) EN coatings with thicknesses of 6, 12, 24, 36......

onto AZ91D magnesium alloy. It was claimed that optimum time for zinc immersion varied from 30 s to 90 s. The nickel deposit with good adhesion strength to the substrate was obtained. The process flow... also analyzed. LUAN et al[32] claimed that the copper deposit was well applied on magnesium alloy from acid and alkali copper electrolyte followed by electroless nickel plating. The relationship......
