Further to the paper by Staron, Jamnig, Leitner, Ebner & Clemens [J. Appl. Cryst. (2003), 36, 415±419], the following points are made. Characterization of the precipitation process in maraging steels is dif®cult, primarily because the precipitates formed are on the nanometre scale. Identi®cation of the precipitate type is complicated by the fact that its composition evolves during ageing, even ...

As the process parameters in LPBF-process influence microstructure, density and hardness of produced parts, their on milling is suspected. For this reason new maraging tool steel alloy Specialis® has been investigated its machinability depending built parameters. The energy density, laser power scan speed examined. During forces are measured as well obtained surface roughness. results confirm i...

In this work, the uniaxial and biaxial fatigue behaviour of maraging steel (18Ni300) obtained by additive manufacturing was studied. The material evaluated using several load paths different levels. predictive capacity life crack initiation angle critical plane methods Liu (I II), Chu, Conle, Bonnen (CCB) were evaluated. results showed that normal stresses had a strong effect on life. general, ...
