Development of Low-Alloy Steels with High Strength and Good Ductility with the Aid of Nanoscale Troostite
We aimed to design nanoscale troositic microstructures in medium-carbon low-alloyed steel by using annealing plus quenching–partitioning–tempering processes to simultaneously obtain high strength and good duct...

Enhancing the NO sensing properties of the SnO2 nanowires sensors by Ar–O2 plasma modification
SnO2 nanowires were prepared in an Au-catalyzed VLS growth process by thermal evaporation. The NO sensing properties of the resistive gas sensor based on the SnO2 nanowires was found to be improved obviously afte...

Enhancement of the photoluminescence properties of Ba1.98SiO4−δN2/3δ:Eu0.02 phosphors and their application to green LEDs
A green emitting Ba1.98SiO4−δN2/3δ:Eu0.02 phosphor with an appreciable intensity was synthesized using the gas-reduction–nitridation (GRN) method. SEM revealed agglomerated Ba1.98SiO4−δN2/3δ:Eu0.02 particles with...

Synthesis of Plastic Mg-Based Bulk-Metallic-Glass Matrix Composites by Bridgman Solidification
The microstructures of the in-situ Mg-based bulk-metallic-glass (BMG) matrix composites synthesized by the copper-mold casting are inhomogeneous, and the optimized mechanical properties are usually realized throu...

Phase transition and mechanical properties of constraint-aged Ni–Mn–Ga–Ti magnetic shape memory alloy
Ni–Mn–Ga Heusler-type ferromagnetic shape memory alloys are attractive materials for micro-actuator, but the relatively poor ductility and low strength of Ni–Mn–Ga alloys have triggered a great deal of interes...

Dielectric and piezoelectric properties of modified lead titanate zirconate ceramics from 4.2 to 300 K
The dielectric and piezoelectric properties (d-p properties) of four kinds of doped lead titanate zirconate piezoelectric ceramics (PZTs) have been measured from 4.2 to 300 K. The d-p properties of the materia...
