Microstructural investigation of direct laser deposition of the Ti–6Al–4V alloy by different melt pool protection conditions

Autor: Mohammad Vakilzadeh Anaraki, Amin Nourollahi, Masoud Barekat, Reza Shoja Razavi, Mohammad Erfanmanesh

Publikováno v: Journal of Materials Research and Technology, Vol 13, Iss, Pp 590-601 (2021)

Titanium alloys require a special protecting atmosphere during the fabrication process due to their strong affinity with oxygen and nitrogen elements at high temperatures. In this study, the effects of different protection conditions on microstructur

Publikováno v: Journal of Materials Engineering and Performance. 30:6557-6567

Literature reports that irregularly shaped powder has lower flowability and apparent density than spherical shaped powder, factors that hinder its use in additive manufacturing, although its cost is potentially lower. In this study, four samples of N

Nanoscale twinning in Fe–Mn–Al–Ni martensite: a backscatter Kikuchi diffraction study

Autor: Mario J. Kriegel, Andreas Leineweber, Alexander Walnsch, Stefan Martin, Martin Thümmler, Peter D. B. Fischer

Publikováno v: Journal of Applied Crystallography

Fe–Mn–Al–Ni martensite distortion gives rise to complex backscattered Kikuchi diffraction patterns which cannot be interpreted by standard procedures. Analysis of these patterns reveals that they arise from nanoscale internal twinning and tetra

Effect of Interstitial Elements on the Cryogenic Mechanical Behavior of FCC High Entropy Alloys

Autor: Nikita Stepanov, Anastasia Semenyuk, M. Klimova, Sergey Zherebtsov

Publikováno v: Materials Science Forum. 1016:1386-1391

High entropy alloys (HEAs) with face-centered cubic (fcc) structure, namely equiatomic CoCrFeMnNi alloy, have attracted considerable attention because of impressive cryogenic mechanical properties – strength, ductility, and fracture toughness. Furt

Role of initial stage nitridation on the mechanical properties of an α-Fe(100) nanofilm in NH3

Autor: Xuefeng Chen, Baijie Qiao, Yu Sun, Ziqiang He, Hao Wang

Publikováno v: Physical Chemistry Chemical Physics. 23:4856-4864

Nitrogen is one of the most significant non-native interstitial elements that is present in the structure of Fe. Initial stage nitridation dramatically influences the mechanical properties of steel, especially for micro to nanoscale applications, but
