Preparation and Properties of La-TZM Alloy Plates

Abstract:

The conventional TZM alloy plates have limited manufacture and application due to the lacking of enough mechanical property. To resolve this question, La doped TZM alloy plate was made by the powder metallurgy. With solid-solid rare La₂O₃ doping, sintering, hot rolling, warm rolling and cold rolling, the molybdenum alloy La-TZM plates were got. This kind of TZM alloy has better properties in both strength and elongation. The tensile strength of La-TZM alloy is 1038 MPa, and the elongation is 10.4%. Metallography test and scanning electron microscopy (SEM) are used to examine the microstructure of the La-TZM alloy plate specimen.
