Study of the Effect of W and Mo Binary Alloying on Fe-Ni36 Invar Alloy Properties

Abstract:

The element W, Mo with paremagnetism and grain refinement is selected according to the theory of magnetostrictive and fine grain strengthening method. The sample with low coefficient of thermal expansion (CTE) and high strength are made by W and Mo alloying of Fe-Ni36, forging and heat treatment. The mechanism of low coefficient of thermal expansion and high strength is analyzed by means of the results of Chemical analysis, metallographic and scanning electron microscopy, grain size, micro-hardness and CTE testing. The result shows: the strength of matrix is improved by W and Mo alloying, the CTE is lower at the same time.
