Control of oxide inclusions in ODS FeCrAl steel by LPBF parameters Heat input is correlated with melt pool geometry and oxide inclusion content. Our researchers have modified laser powder bed melting parameters to produce an ODS-FeCrAl steel free of Y-Al-O oxide inclusions from a Fe-22Cr-5.1Al-0.5Ti-0.26Y and TiO₂powder mixture. This research provides a feasible method for […]

Cavitation Erosion Resistance of Fe50Mn30Co10Cr10 High Entropy Alloy HEA powder, composed of Fe50Mn30Co10Cr10, with a particle size ranging from 45 to 105 μm, was prepared in an argon atmosphere using gas atomization method. The substrate is AISI 304 stainless steel board. The laser scanning follows zig-zag route. And the powder is transferred in a speed

Laser Cladding CuAl10 Copper Alloy Effect of Ni Addition on Microstructure and Properties of Laser Cladding CuAl10 Copper Alloy In the fields of marine engineering, chemical equipment, etc., copper alloys are widely used due to their excellent thermal conductivity and corrosion resistance, but their insufficient surface hardness and wear resistance often limit their service life.

Selection of HIP Temperature for LPBF Superalloy Rene125 Rene125 alloy is a directionally solidified nickel-based superalloy with excellent high temperature mechanical properties, outstanding oxidation resistance and remarkable creep resistance. These properties make it particularly suitable for high temperature components in aerospace applications, such as turbine blades. Although traditional directional solidification technology (DS) has advantages in

Effect of Al2O3 nano-particles on properties of CoCrNi LPBF part Experiment This study used CoCrNi alloy powder and Al₂O₃ powder as raw materials. CoCrNi alloy powder was prepared by vacuum gas atomization, and the powder particle size range was 15-53 μm. The particle size of Al₂O₃ powder was 38-74 μm. After the raw material powders

Study on the Effect of WC Addition on the Properties of M42 Powder In the field of high-end manufacturing, M42 alloy powder has become the core material for cutting tools, aerospace components and precision molds due to its excellent red hardness, wear resistance and high temperature strength. However, its performance is highly dependent on composition
