Optimization and controlling of the microstructure and mechanical properties of high-Nb TiAl alloy by extrusion temperature

Hot extrusion is an effective route to tailor the microstructure and mechanical performance of TiAl intermetallic alloys. In the present work, a Ti-45Al-8Nb-0.2W-0.1B alloy was multi-pass extruded at five temperatures spanning the (α + γ) two-phase region to the α single-phase re...

Study on the Hydrogen Storage Properties of LaNi5 Framework Materials

The hydrogen storage properties of LaNi5 framework materials prepared by filling porous substrates with LaNi5 powders were studied. Aluminum silicate fiber blanket, 110 pores per inch (PPI) polyester foam, and 70 PPI and 110 PPI nickel foams were used as porous substrates, and 45...

Correlative microscopy reveals chemical short-range order and native oxide in medium-entropy alloys

High- and medium-entropy alloys can exhibit exceptional sets of mechanical and catalytic properties underpinned by the vast array of local atomic arrangements. Among the key features governing properties is the self-assembly of specific atomic neighborhoods, a process known as ch...
