1,Description:
Molybdenum-lanthanum alloys, also known as Mo-La alloys, are composite materials that contain molybdenum as the primary constituent with the addition of a small percentage of lanthanum. Here is an English description of Mo-La alloys:
Mo-La alloys are characterized by their excellent high-temperature strength, remarkable creep resistance, and improved ductility compared to pure molybdenum. The addition of lanthanum, a rare-earth element, enhances the mechanical properties and performance of molybdenum in various applications.
Mo-La alloys exhibit higher recrystallization temperatures, making them suitable for use in elevated temperature environments. They maintain their mechanical properties at temperatures up to 1,900°C (3,450°F), making them ideal for applications requiring excellent thermal stability and resistance to deformation, such as high-temperature furnace components and aerospace engine parts.
The addition of lanthanum to molybdenum refines the grain structure and improves the ductility of the alloy, allowing for easier forming and shaping processes. Mo-La alloys can be readily machined, rolled, forged, or drawn into different shapes and sizes, offering versatility in manufacturing and design.
