High-performance additives manufactured by Al alloys provide significant potential for lightweight applications and have attracted much attention nowadays. However, there is no research on Sc, Er Zr microalloyed alloys, especially concerning corrosion behavior. Herein, crack-free dense Al-Mg-Mn-Sc-Er-Zr were processed selective laser melting (SLM). After optimizing the process parameters of SLM...

First-principles energetics analyses were performed to investigate the nucleation of (Y–Si–O) nano-clusters (NCs) in nano-structured ferritic alloys (NFAs). It was predicted that (Y-Si–O) NCs follows same general pathway as previously found for (Y–Ti/Al/Zr–O) NFAs: they all tend begin with (O–O) pairs and grow (O–Y)-cores further larger by attracting Y other solute elements nearby. Nucleation a...

To optimize the mechanical properties for biodegradable orthopedic implant, microstructures and tensile properties of Mg-Zn-Y alloys containing long period stacking ordered (LPSO) phase were investigated. For the as-cast Mg(100-3x)(Zn(1)Y(2))(x) (1 ≤ x ≤ 3) alloys, volume fraction of 18R LPSO phase increases with increasing the contents of Zn and Y. Mg(97)Zn(1)Y(2) alloy exhibits the optimal co...

Small angle neutron scattering (SANS) was used to quantify the precipitate characteristics (i.e., mean precipitate size, number of precipitates, and distribution broadening) in X-70 and X-80 pipeline steel and in grades 80 and 100 microalloyed steel plate. The precipitate distributions measured for the different steels were correlated with the finish rolling temperature (FRT) and cooling interr...

The liquidus surface projection and isothermal sections at 1100 1000 °C of the Co–Nb–Zr system were constructed by analyzing solidification morphology as-cast alloys annealed microstructure equilibrated diffusion couples. Six primary areas obtained in projection, four deduced from binary phase diagram. Additionally, three three-phase regions five determined sections. Based on experimental infor...

Non-evaporable Ti-Zr-V ternary getters (NEGs) were studied by means of excitation energy resolved photoelectron spectroscopy (ERXPS). We attempted a quantitative study of the in-depth redistribution of the NEG components during activation. The samples were prepared ex-situ by DC magnetron sputtering on a stainless-steel substrate. The ERXPS measurements were carried out at two incident photoele...
