Production of in Situ Cu/NbC Nanocomposites Powders via Mechanical Alloying and Investigation the Mechanical (Wear Resistance) and Physical (Electrical Conductivity) Properties, M.Sc. Thesis Sharif University of Technology ; Abachi, Parvin (Supervisor) ; Purazarang, Kazem (Supervisor)
Abstract
For application such as electrical contacts and spot welding electrodes, both high electrical conductivity and wear resistance are required. Additionally, such parts should have structural stability at evaluated temperature. Copper based composites containing carbides or oxides reinforcement can be the good choice for production of such parts. In present work, in-situ Cu/NbC composite via mechanical alloying with homogenous distribution of nano reinforcement particle has been produced. For this purpose, in first stage, copper powder was milled with 5, 8, 10 and 12 wt. % of niobium powder in two types of mills, i. e. vibratory dicky mill and planetary ball mill for 5 and 32 h respectively. At...
