The production of molybdenum-lanthanum (Mo-La) alloy sheets typically involves a series of manufacturing processes. These processes may include: Raw material preparation:
The first step involves obtaining the necessary raw materials, such as molybdenum and lanthanum, in the form of powders or other suitable raw materials. These raw materials are selected based on their purity and desired alloy composition. Blending and Mixing: Molybdenum and lanthanum powders are mixed together in precise proportions to obtain the desired alloy composition. The mixture is mixed thoroughly to ensure even distribution of ingredients. Compaction: The combined powder mixture is then compacted under high pressure to form a dense and coherent green body. Compaction can be achieved using techniques such as cold isostatic pressing (CIP) or uniaxial pressing. Sintering: The green body is sintered in a high-temperature furnace under a controlled atmosphere to achieve solid-state diffusion bonding between molybdenum and lanthanum particles. This process results in the formation of a dense and fully consolidated Mo-La alloy material. Hot rolling: The sintered Mo-La alloy material is then subjected to a hot rolling process to obtain the required thickness and mechanical properties. The hot rolling process involves passing the material through a series of rolls at high temperatures to reduce its thickness and improve its microstructure. Annealing: After hot rolling, the Mo-La alloy plate may undergo an annealing process to eliminate internal stress and further refine its microstructure. Annealing is usually performed at a specific temperature and for a controlled duration. Surface Treatment and Finishing: Mo-La alloy plates can undergo additional surface treatments such as pickling, machining or polishing to achieve the required surface finish and dimensional tolerances. Quality control and testing: Throughout the production process, Mo-La alloy sheets undergo strict quality control measures and testing to ensure that their mechanical properties, microstructure and chemical composition meet the specified requirements.
The above production methods are a general overview and may vary depending on the specific manufacturing techniques and equipment used by different manufacturers. The precise steps and parameters involved in the production of Mo-La alloy sheets will depend on factors such as required sheet size, mechanical properties and end use.
