We first successfully achieved the two types of distinct texture control in low-modulus beta-type Ti–15Mo–5Zr–3Al alloy products using selective laser melting. Bidirectional scanning with and without a rotation 90° between layers gave rise to different textures preferential orientations 〈001〉 〈011〉 along building direction, respectively. Control growth behavior columnar cells melt pools via strategies enabled generation such textures. The obtained material exhibits low Young's modulus 68.7 ±...
A novel equiatomic TiNbTaZrMo high-entropy alloy (HEA) was developed as a new metallic biomaterial. The constituent elements of the HEA were biocomparable, and designed based on parameters such mixing enthalpy (ΔHmix), omega parameter (Ω), delta (δ), valence electron concentration (VEC) theory. bcc solid solution phases with different lattice constants obtained in as-cast annealed states. showed considerable strength deformability superior biocompatibility comparable to pure Ti. This study...

The CLM was composed of major 〈011〉 and minor 〈001〉 aligned along the build direction, stemmed from vertical approximately ±45° inclined columnar cells formed central side parts melt-pools, respectively. development found to largely improve material properties strengthening product,...
A new general purpose fixed target facility is proposed at the CERN SPS accelerator which aimed exploring domain of hidden particles and make measurements with tau neutrinos. Hidden are predicted by a large number models beyond Standard Model.

Additive manufacturing offers an exclusive way of anisotropic microstructure control with a high degree freedom regarding variation in process parameters. This study demonstrates unique texture formation Inconel 718 (IN718) using bidirectional laser scan powder bed fusion (LPBF) for tailoring the mechanical properties. We developed three distinctive textures IN718 LPBF: single-crystal-like (SCM) <110> orientation build direction (BD), crystallographic lamellar (CLM) <110>-oriented main layer...

This paper clarified a novel strategy to improve the tensile properties of Ti-48Al-2Cr-2Nb alloys fabricated by electron beam melting (EBM), via finding development unique layered microstructure composed duplex-like fine grains layers and coarser γ layers. It was that mechanical alloy EBM can be controlled varying an angle θ between EBM-building directions stress loading direction. At room temperature, yield strength exhibits high values more than 550 MPa at all orientations investigated (θ...
The strength of bone depends on quantity and quality. Osteocalcin (Ocn) is the most abundant noncollagenous protein in produced by osteoblasts. It has been previously claimed that Ocn inhibits formation also functions as a hormone to regulate insulin secretion pancreas, testosterone synthesis testes, muscle mass. We generated Ocn-deficient (Ocn-/-) mice deleting Bglap Bglap2. Analysis Ocn-/-mice revealed not involved regulation quantity, glucose metabolism, synthesis, or orientation degree...
