MoLa and MoY
MoLa and MoY molybdenum alloys for high-temperature applications
The addition of 0.03 to 0.7 percent by weight of lanthanum oxide or yttrium oxide to molybdenum significantly improves the high-temperature strength and increases the recrystallization temperature compared to pure molybdenum. These oxide particles act as barriers in the microstructure, effectively inhibiting unwanted grain growth at high temperatures – a common problem with pure molybdenum. MoLa and MoY alloys are therefore particularly suitable for demanding high-temperature applications where pure molybdenum alloys reach their limits due to grain growth and loss of strength, such as in furnace components, heating wires, heating cables, furnace boats, filaments and pins and wires for lamps and coils.
