| 摘 要： | 1. Introduction W-Cu alloys are widely used in many fields due to their superior properties 1]. With the rapid de-velopment of technology, more demands are being made on the W-Cu alloys. For instance, higher heat conductivity, lower thermal expansion coefficient, and more rigorous air tightness are required when these alloys are used for electronic package materi-als, such as heat sink materials. Especially, the re-quirement of more rigorous air tightness means that the W-Cu alloys must pos…

| Abstract: | The sintered W-15wt.%Cu alloys fabricated by mechanical alloying were re-sintered under pressure to increase the density and improve the properties of these alloys. The pressure was applied vertically along the axis of the sintered sample. Properties such as density, hardness, and bending strength were measured. The microstructures of the sintered bodies were observed. The results showed that the subsequent pressure sintering could increase the density of the sintered W-15wt.%Cu alloys. Their hardness, bending strength, and some other physical properties were also improved by this subsequent densification treatment. |
