| description | The mechanical properties and microstructure of Cu-based diamond ultrathin sawing matrixes prepared using a cold pressing/sintering process were investigated. The experimental results show that the phases of Cu-based samples after sintering are mainly composed of a Cu substrate phase, Fe, (Cu, Sn), and Cu3.8Ni phases. When the pressure was increased to 187 MPa, Fe aggregation was generated, and this slowed the alloying and compaction of the Cu-based matrixes during the sintering process and weakened the corresponding mechanical properties. The densification, tensile strength, and elastic limit of Cu-based samples after sintering were best at a pressure of 187 MPa.
