Precipitation in a Ag-Containing Mg-Y-Zn Alloy
The precipitation in a Mg-6Y-2Ag-1Zn-0.6Zr (wt pct) alloy during isothermal aging at and above 473 K (200 °C) has been examined systematically using conventional transmission electron microscopy, high-angle an...

Precipitation hardenable Mg-Ca-Al alloys
The age-hardening responses and the corresponding microstructures of Mg-0.5Ca-xAl (x = 0, 0.1, 0.3, 0.5, 1 wt. %) alloys were investigated by hardness tests and transmission electron microscopy. For the optimum A...

Effect of Mn Addition on Creep Property in Mg-2Al-2Ca Systems
Planar Al2Ca phase forms on the basal plane in the as-cast AX22 and AXM220 alloys. In the AXM220 alloy, Mn is detected in the Al2Ca phase. The number density of the Al2Ca phase does not alter, irrespective of the...

Laser-assisted Atom Probe Analysis of Bulk Insulating Ceramics
A Yb:KGW femtosecond laser (400 fs) with 3rd and 4th harmonic generators (wavelength = 343 and 258 nm) was adopted to a locally built 3DAP instrument to assist field evaporation from ceramics tips that were bo...

An investigation of microstructure and grain-boundary evolution during ECA pressing of pure aluminum
High-purity aluminum (99.99 pct) was processed by equal-channel angular pressing (ECAP) at room temperature through a die with a 90 deg angle between the die channels. Samples were examined by transmission ele...

Synthesis of the B1-type tantalum nitride by shock compression
B1-type tantalum nitride (polycrystalline bulk state) was synthesized by shock compression. Shock-compression recovery experiments of the porous sample of tantalum nitride with a hexagonal structure (CoSn-type...
