Additively manufactured alloys are known to possess sufficient tensile strength-ductility combinations, matching their conventionally processed counterparts, and yet fail to perform under cyclic loading conditions. The complex, heterogeneous microstructure, resulting anisotropy and porosity distribution, as well as the surface roughness in additive...
In space engines with liquid cryogenic LH2/ LO2 propellants, bearings are used in cryopumps subjected to harsh working conditions. High nitrogen martensitic stainless (HNMS) steel is a newly developed steel modifying currently used AISI 440C steel by partial substitution of C with N and is a potential replacement for AISI 440C as an antifriction be...
Development of the space engines with liquid propellants necessitates the use of bearings of high quality. During recent years, a new family of high strength corrosion resistant steels, with partial replacement of carbon by nitrogen, known as high nitrogen steels were developed having higher impact strength and fracture toughness coupled with high...
Bearings are highly engineered components which have to tolerate vibratory stresses, bending moments and high rotational speeds in cryogenic application. AISI 440C is most widely used for anti-friction bearings due to its good strength and high hardness but is prone to carbide banding and failure during service. High nitrogen martensitic stainless...
The development of space engines with liquid propellants require use of highly engineered bearings. High nitrogen martensitic stainless steel (HNMS) is the newly developed steel and is the potential candidate for anti-friction bearings in cryogenic engines in launch vehicles. The present paper aimed to assess the effect of cryogenic treatment on HN...
The comparative study of high temperature deformation behaviour of P91, RAFM-CLAM and Low C RAFM-CLAM steels was done from compression deformation data in the temperature range of 850–1100 °C and the strain rate range of 10⁻³–10 s⁻¹. The processing maps in terms of strain rate sensitivity (m), % efficiency of power dissipation (ƞ) and the instabili...
India-specific reduced activity ferritic martensitic steel (INRAFM), a modified 9Cr-1Mo grade, has been developed by India as its own structural material for fabrication of the Indian Test Blanket Module (TBM) to be installed in the International Thermonuclear Energy Reactor (ITER). The extensive study on mechanical and physical properties of this...
