Additive manufacturing (AM) is increasingly used for the manufacturing of tools and dies; in
this respect, apart from the optimization of processing parameters, it is important to establish …

The cooling rate in molten metal gas atomization is the key determining factor for the
microstructure of metal powders. Mathematical expressions for cooling rates often include …

Die steels with regulated austenitic transformation during exploitation (RATE steels) are a
new type of tool steels. These steels are the only ones for which the phenomenon of 'hot …

Abstract Fe-14Cr-0.4 Ti-0.25 Y 2 O 3 ferritic steels were produced by varying the amount of
residual process control agent, PCA (ethanol), in the ball-milled powders and changing the …

The strengthening mechanisms in an ultrafine grained (UFG) powder metallurgical (PM) tool
steel produced by high energy mechanical milling (MM) and spark plasma sintering (SPS) …

In order to remain competitive to powder metallurgy and spray forming, further improvements
of a classical production route are needed and desired. This paper describes the means by …

Centrifugal atomization is a rapid solidification technique involving fast cooling rates to
produce high-quality powders. The final microstructure of the atomized particles is closely …

Y-Zr-O complex oxide dispersion-strengthened Mo alloys with different Zr contents (Mo-2Y 2
O 3–0.6 Zr, Mo-1Y 2 O 3–0.6 Zr, and Mo-1Y 2 O 3–1.2 Zr, wt%) were designed and …

The effect of the processing route and the addition of 20 vol% TiC particles on the fracture
toughness of the hot work tool steel AISI H13 was investigated. To this end, as-atomized …

In order to investigate the influence on mechanical properties of grain size in the near-
micrometer regime, samples of Fe with nearly full density were prepared using the spark …
