Characteristics and Challenges of Multi-Metal Smelting
Large Melting Point Differences
Different metals can have vastly different melting points. For example, the melting point of tungsten is 3422°C, while that of molybdenum is 2623°C. Achieving uniform fusion at such high temperatures is a significant challenge.
01
Poor Mutual Solubility
Some metals are difficult to dissolve in each other in their molten state, often resulting in layering or segregation, leading to uneven alloy composition.
02
Formation of Brittle Phases
Different metals may form brittle intermetallic compounds during fusion, which can negatively affect the mechanical properties of the material.
03
Complex Process Control
Multi-metal smelting requires precise control over temperature, time, and atmosphere (such as vacuum or inert gas protection) to ensure uniformity in alloy composition and stability in performance.
