Fabrication of fully dense and highly conductive copper alloy parts via laser-based additive manufacturing (L-AM) is challenging due to the high optical reflectivity at λ = 1060 – 1080 nm thermal conductivity. To overcome this, use optically absorptive surface-modified powders being evaluated in laser powder bed fusion (LPBF) process. Although exhibit absorption room temperature, not all them allow fabrication a power below 500 W. Accordingly, this article proposes carburized CuCr1 for...
Modeling concurrent nucleation and growth in the phase-field framework on experimentally relevant length scales remains a significant challenge due to spatial resolution driving force limitations. This work proposes modeling that overcomes these challenges by integrating explicit method within recently developed high-driving model investigate influence of cooling rate solid-state growth. The accurately captures behavior individual nuclei across varying scales, allows efficient one grid point...
In this study, the phase evolution and properties of CoCrCuFeNiSix (x = 0, 0.3, 0.6 0.9 atomic ratios) high entropy alloys prepared by powder metallurgy route is investigated. The x-ray diffraction analysis reveals presence mixed phases face-centered body-centered cubic after 20 h milling. addition Si (0.3, 0.9) favors formation structure during mechanical alloying. However, heating spark plasma sintering encourages transformation evolved alloying to sigma phases. microhardness value...
