Description
Summary:The stress where the cast alloy starts to deform plastically is about twice larger than that of spark plasma compacted alloys. [Display omitted] •Metal matrix composites of Cu-Ag alloys are studied.•Tensile deformation of different alloys is interpreted.•Spark plasma sintered alloys are more suitable for applications.•The interfaces in the alloys compacted due to plasma have better properties. The role of interfaces in metal matrix composites of Cu-Ag alloys deformed in tension is studied. Five types of samples are considered: alloys prepared by traditional casting and alloys compacted by spark plasma sintering are completed with pure elements, copper and silver. Due to more pronounced interfaces in the cast alloys, plastic deformation occurs at higher stresses and hence the dendritic structures of cast alloys are less suitable for applications.
