The high-energy milling is one of the most extended techniques to produce Oxide dispersion strengthened (ODS) powder steels for nuclear applications. consequences high energy mill process on final powders can be measured by means deformation level, size, morphology and alloying degree. In this work, an ODS ferritic steel, Fe–14Cr–5Al–3W-0.4Ti-0.25Y2O3-0.6Zr, was fabricated using two different mechanical (MA) conditions (Mstd Mact) subsequently consolidated Spark Plasma Sintering (SPS)....
A novel approach to incorporating oxide formers into ferritic ODS production has been developed using the co-precipitation technique. This method enables tailored design of complex nano-oxides, integrated during Mechanical Alloying (MA) and precipitated Spark Plasma Sintering (SPS) consolidation. Findings illustrate that effectively produces nano-powders with customised compositions, enriching Y, Ti, Zr in grade condition subsequent precipitation. While addition Y–Ti–Zr–O nano-oxides did not...
Two different zirconium contents (0.45 and 0.60 wt.%) have been incorporated into a Fe-14Cr-5Al-3W-0.4Ti-0.25Y2O3 oxide dispersion-strengthened (ODS) steel in order to evaluate their effect on the final microstructure mechanical properties. The powders with targeted compositions were obtained by alloying (MA), subsequently processed spark plasma sintering (SPS) at two heating rates: 100 400 °C·min−1. Non-textured bimodal microstructures composed of micrometric ultrafine grains obtained....
In this work, new oxide dispersion strengthened (ODS) ferritic steels have been produced by powder metallurgy using an alternative processing route and characterized afterwards comparing them with a base ODS steel Y2O3 Ti additions. Different alloying elements like boron (B), which is known as inhibitor of grain growth obtained pinning boundaries, complex compounds (Y-Ti-Zr-O) introduced to the 14Cr prealloyed mechanical (MA) were further consolidated spark employing plasma sintering (SPS)....
QP steels and other third generation AHSS possess outstanding combinations of strength ductility, making them very attractive for the automotive sector. However, an Achilles heel these materials is their rather limited weldability. Despite obvious importance this problem, few works have been published characterising 3 rd welded joints. For current contribution, novel stainless were investigated. Resistance spot joints prepared following treatment sheets. Results paint baking revealed a high...
There is a general need for alternative structural materials to improve power plants’ efficiency and reduce CO 2 emissions. Within this framework, two new compositions of temperature-resistant sintered ODS ferritic steels (14Cr-5Al-3W), strengthened by fine dispersion precipitates (5·10 22 ox. /m 3 ), have been developed. This work focuses on creep properties microstructure evolution. The resistance (at 650°C) could be improved prior microstructural optimisation, thanks the consolidation...
