文摘
- •
We succeeded in applying selective electron beam melting to the AlCoCrFeNi high-entropy alloy.
- •
The mechanical properties of the molds were far superior to those of the corresponding castings.
- •
The ductility in particular was remarkably enhanced by selective electron beam melting.
- •
The fracture strength was above 1400 MPa, which was more than six times higher than that of SUS304.
