Liquid phase sintering (LPS) is a sintering method in which some substances enter the liquid phase during the sintering process and promote the densification of particles. For molybdenum-copper alloys, since the melting point of molybdenum is as high as 2617 °C, while the melting point of copper is only 1083 °C, when the sintering temperature exceeds the melting point of copper but is much lower than the melting point of molybdenum, the copper will partially melt and fill the pores…

The optimization of the powder metallurgy is crucial to the final performance of molybdenum-copper materials, which mainly affects the following aspects: 1. Density Density is one of the key parameters that determine the properties of alloys. Increasing the density can effectively reduce the porosity of the material and improve its thermal conductivity and mechanical properties. Measures such as the use of ultra-fine powders, optimized sintering temperatures, and extended holding times can increase the density of the final material. 2. Thermal…

There are various methods for preparing molybdenum copper alloy, among which powder metallurgy process has become one of the most commonly used methods in industrial production because of its strong process controllability, low cost, and the manufacture of parts with complex shapes.

Molybdenum-copper alloy is usually formed by combining copper and molybdenum through sintering, hot pressing and other processes. Molybdenum has an extremely high melting point and a low coefficient of thermal expansion, while copper has excellent thermal conductivity, which allows the combination of the two to effectively dissipate heat in high-temperature environments without cracking or failing due to differences in thermal expansion. Therefore, molybdenum-copper heat sink materials are widely used in fields that require high thermal conductivity and thermal stability, such…

Powder metallurgy (PM) and liquid phase sintering (LPS) are two common process methods in the preparation of molybdenum-copper alloys. Although both can be used to produce molybdenum copper, there are obvious differences in terms of process, material properties, cost and application fields. 1. Material density and structural uniformity The powder metallurgy process mainly relies on solid-phase sintering, due to the limited shrinkage of the material in the sintering process, the density of the final product is usually low, and it…
