摘要: Al matrix composites reinforced with 40 vol% Fe50.1Co35.1Nb7.7B4.3Si2.8 glassy particles have been produced by powder metallurgy, and their microstructure mechanical properties investigated in detail. Different processing routes (hot pressing hot extrusion) are used order to consolidate the composite powders. The homogeneous distribution of reinforcement decrease particle size obtained through ball milling. This has a positive effect on hardness strength composites. Mechanical tests show that pressed samples increases from 51–155 HV, rises 220–630 MPa extending milling time 1–50 h. use extrusion after reduces both composites: however, it enhances plastic deformation significantly.
