Mechanical Properties of an Ultrahard In Situ Amorphous Steel Matrix Composite

Arash Yazdani,

Abstract: We report compression tests on micro‐pillars manufactured from bulk specimens of partially devitrified SAM2×5 (Fe49.7Cr17.7Mn1.9Mo7.4W1.6B15.2C3.8Si2.4). Yield strength values of ∽6 GPa were obtained. Such a high strength can be attributed to the higher glass transition temperature (883 K) of this material, which impedes the multiplication of shear bands under loading, and to the presence of hard crystalline domains that result from devitrification of the amorphous powders during powder consolidation. The Vick… Show more
