Nanostructurization of Fe-Ni Alloy

Data about an effect of cyclic γ-α-γ martensitic transformations on the structure state of reverted austenite Fe-31.7 wt.% Ni-0.06 wt.% C alloy are presented. The effect of multiple direct γ-α and reverse α-γ martensitic transformations on fragmentation of austenitic grains has been investigated by electron microscopy and X-ray diffraction methods. An ultrafine structure has been formed by nano...

Mechanical Alloying as an Effective Way to Achieve Superior Properties of Fe–Co–Ni Binder Alloy

This study addresses the fabrication of nanocrystalline Fe–Co–Ni alloy using two operations: mechanical alloying (MA) of elemental powders and hot pressing (HP). The evolution of the phase composition and structure of the powder particles after MA was investigated. Ball milling with rotation speed 700 rpm for 15–20 min allows the production of a bcc Fe-based supersaturated solid solution. Durin...

Effects of Alloying Elements on Martensitic Transformation Behavior and Damping Capacity in Fe-17Mn Alloy

Effect of carbon and Ti on 7-s martensitic transformation behavior and damping capacity has been investigated in an Fe-17Mn alloy. The suppressive force of carbon against 7-s transformation increases linearly with an increase in carbon content, lowering M, temperature and volume fraction of s martensite. Carbon deteriorates damping capacity by reducing the area of y l e interfaces and by decrea...

Glass formation in a (Ti,Zr,Hf)–(Cu,Ni,Ag)–Al high-order alloy system by mechanical alloying

In this work, glass formation under high-energy ball milling was investigated for a (Ti0.33Zr0.33Hf0.33)50(Ni0.33Cu0.33Ag0.33)40Al10 high-order alloy system with equiatomic substitution for early and late transition-metal contents. For comparison, an amorphous alloy ribbon with the same composition was prepared using the melt-spinning method as well. Structural features of the samples were char...
