Additive manufacturing (AM) rapidly produces complex shapes crucial for energy technologies and engineering designs. In this work, the microstructure mechanical properties of additive manufactured Grade 91 (modified 9Cr–1Mo) ferritic/martensitic (FM) steel were investigated. Computational thermodynamics, synchrotron X-ray diffraction, scanning electron microscopy, microhardness testing utilized to quantify (crystallographic phases, microstrain), lattice parameters, as functions build...
Plasma-facing components (PFCs) are among the most critical gaps for fusion energy to establish technical and economic feasibility. Tungsten as a first wall/blanket material in PFCs requires be integrating with reduced activation ferritic martensitic (RAFM) steels structural component. Currently, major drawbacks requirement of brazing, formation brittle interface, large difference between coefficients thermal expansion tungsten steel. Here, novel transitional multilayer structure was...
The leading design for plasma-facing high heat flux components in proposed fusion reactors involves joining tungsten tiles to underlying reduced activation ferritic-martensitic (RAFM) steel structures. Due significant differences the physical properties between W and steel, an effective method them while preserving mechanical microstructural under service thermo-mechanical load is yet be demonstrated. A transitional multilayer consisting of three layers (VCrTi, VCrAl, FeCrAl) designed with...
Critical aspects of innovative design in engineering disciplines like infrastructure, transportation, and medical applications require the joining dissimilar materials. This study investigates literature on solid-state bonding techniques, with a particular focus diffusion bonding, as an effective method for establishing bonds. Welding brazing, while widely used, may pose challenges when materials large differences melting temperature can lead to mechanical property degradation. In contrast,...
