“…[1] Among all the alloying elements for the Fe matrix, Ni is a significant element because of its versatile characteristics. [2][3][4] It improves the toughness, corrosion, and oxidation at elevated temperatures, and mechanical properties, and prevents scale forming of Fe-based materials. For example, high wear resistance and better mechanical properties have been reported for Fe-2wt% Ni alloy produced through the powder metallurgy (P/M) route.…”

In this work, the nanoindentation‐induced deformation behavior in sintered Fe36Ni is investigated using experiments and molecular dynamics simulations. The Fe36Ni alloy is synthesized through the powder metallurgy route. A microstructural study of the sintered sample reveals the formation of both hard α‐(Fe, Ni) and soft γ‐(Ni, Fe) phases due to compositional inhomogeneity, and increasing the sintering temperature enhances the γ‐(Ni, Fe) phase formation. The experimentally measured nanoindentation features are correlated to atomistic origin using molecular dynamics simulation. Deformation behavior is explored using local shear strain and atomic displacement plot, and a detailed investigation of various dislocation nucleation and their interaction is performed to gain insights into the mechanisms governing plastic deformation. The plastic deformation of α‐(Fe, Ni) phase is governed by dislocation with Burger's vector b = ½ <111> and b = <100> whereas, sessile dislocations such as Stair‐rod (b = 1/6 <110>), Frank (b = 1/3 <111>), and Hirth lock (b = 1/3 <100>) are found to be responsible for the plastic deformation and also contribute in strain hardening of γ‐(Ni, Fe) phase.

“…The strengthening of Invar by precipitation of Ti and Cr carbides also was investigated [ 4 , 20 ]. The effect of Ti and V on hardness and tensile strength of Invar type alloy has been studied [ 21 ]. It has been reported that the tensile strength of Invar can be increased up to 650 MPa by precipitation of Cr carbides [ 4 ].…”

The composite materials are used on an increasingly large scale in top fields, such as the automotive, aerospace, and nuclear industries, due to the combination of the specific properties of the composite components. Invar/WC nanocrystalline composite compacts were successfully obtained by spark plasma sintering from mechanical milled composite powder. The influence of the amount of tungsten carbide (WC) on sintering, coefficient of thermal expansion (CTE), and hardness has been investigated. The relative density and hardness of Invar/WC composite compacts increases with increasing the WC content up to 10 vol.%. At higher amount of WC (15% vol.), the relative density and hardness of the Invar/WC composite compacts decreases. The temperature up to which CTE remains at a low value (0.6–1) × 10−6 °C−1 is influenced by the WC content and decreases with the WC amount of increase.
