A rare earth composite material

Abstract

The invention discloses a rare earth composite material. The chemical formula of the rare earth composite material is R-H-M, wherein R is selected from Nd, Pr, Dy, Tb, Ho, La, Ce, Pm, Sm, Eu, Gd, At least one of Er, Tm, Yb, Lu and Y elements, the M is selected from at least one of W or Mo, the composition of the rare earth composite material includes 4.5wt% to 50wt% of R, 0.08wt% to 0.08wt% 1.65 wt% H, balance M. The rare earth composite material of the invention has high release energy, can achieve high energy release in an oxygen-free environment, and significantly improves the application environment of the metal energy release material.

Description

technical field [0001] The invention relates to metal materials, in particular to a rare earth composite material. Background technique [0002] For the currently known metal energy release materials, the energy release mechanism is that an element that is easier to react with oxygen reacts with oxygen, releasing a large amount of heat; the second is the reaction between metal and metal or between metal and intermediate products. At present, metal energy release materials mainly use Zr, Al and other highly active elements as the main energy release elements, and achieve combustion effect in an environment with high air or oxygen content, but usually in low-pressure oxygen-deficient, underwater and other environments. poor, and its mechanical properties are insufficient, making it difficult to use in structural components. [0003] Rare earth metals are highly active materials, and their combustion energy release value is much higher than that of existing metal energy releas...

AI Technical Summary

Problems solved by technology

However, rare earth metals are too active to be directly stored in the air for a long time in a simple state, and the energy release effect will become poor after forming an intermetallic compound with other metals.
