Effects of Additive Elements on Properties of Fe-Cr-B Gas Atomized Powder with High Hardness

In order to obtain a high hardness shot peening media, the properties of Fe-8%Cr-6.5%B media (Base media) with several additive elements were investigated. Fe-8%Cr-6.5%B-X%M media (X%M=2%Zr, 2%Nb and 2~16%W; Denoted hereafter as X%M media) were produced by gas atomization. Vickers hardness, density...
