چکیده
Abstract In this work, we demonstrate the feasibility of manufacturing an iron-based oxide-dispersion-strengthened (ODS) PM2000 composite material with chemical composition Fe20Cr4.5Al0.5Ti + 0.5Y 2 O 3 (in wt.%) via advanced directed energy deposition (DED) process high-speed laser cladding (HSLC). The characteristic high solidification rates HSLC processes allow successful dispersion nano-scaled yttrium-based oxides in ferritic stainless steel matrix. effective suppression nano-particle agglomeration during melting stage, which is frequently observed conventional DED ODS materials, reflected by smaller dispersoid sizes and corresponding higher hardness manufactured specimen compared to DED-manufactured counterparts.

Fabrication of Fe-Cr-Al Oxide Dispersion Strengthened PM2000 alloy using Selective Laser Melting**
The expansion in application of the selective laser melting (SLM) process for fabrication of new alloy materials continues. However, to date, there has been no investigation of the effect of this process on the final microstructure of ‘melt sensitive’ powder alloys such as mechanically alloyed oxide dispersion strengthened (ODS) FeCrAl. In this study commercial PM2000 powder, a ferritic ODS all...
متن کاملLaser-powder-material interactions in the laser cladding process
In this paper we present briefly two possible approaches for modelling the laser cladding process. The first approach is 2D and consists in finding the shape of the molten pool given the fraction of the laser power which is available at the surface of the workpiece and given the amount of powder sticking to the molten pool. The powder reaching the workpiece is assumed to melt instantaneously at...
متن کاملManufacturing Process Routes for Reinforcing Steels
In the UK, and in many other parts of the world, reinforcing steels are specified to British Standards, or very similar, which in the main do not specify process routes. As a result, many specifiers, purchasers and users are unaware of the different process routes used in their manufacture. Manufacturing process routes for some of the reinforcing steel products used have changed considerably in...

Microstructure, Mechanical and Tribological Properties of Oxide Dispersion Strengthened High-Entropy Alloys
A novel metal matrix composite CrMnFeCoNi with Y₂O₃ as reinforcement phase was designed and manufactured by mechanical alloying and spark plasma sintering. After sintering at 900 °C for 5 min, the microstructure consisted of a FCC matrix and Y₂O₃ nanoparticles. The addition of 0.25 wt % Y₂O₃ increased the room temperature tensile strength of the CrMnFeCoNi base from 868 MPa to 1001 MPa, while t...
