2018-03-29

Multicomponent carbide thin films of (CrNbTaTiW)C (30–40 at.% C) with different metal contents were deposited at different temperatures using non-reactive DC magnetron sputtering. The lattice distortion for the metal lattice was estimated to vary from about 3...

Laser welding of Cu-Al-Be shape memory alloys: Microstructure and mechanical properties

10.1016/j.matdes.2018.03.066

2018-03-29

Cu-based shape memory alloys are potential substitutes of NiTi shape memory alloys, owing to their lower production costs and recent increase in their mechanical properties arising from better control of the microstructure. The development of joining technolo...

Development of an improved prediction method for the yield strength of steel alloys in the Small Punch Test ☆

10.1016/j.matdes.2018.03.064

2018-03-29

The Small Punch Test (SPT) is a miniaturized test to characterize the mechanical properties of the materials. The load-displacement curve obtained by this test does not directly provide the material parameters, and linear correlations between data obtained fr...

Coupling effects of deformation and thermal exposure on the precipitation behaviors of βo(ω) phases in a high Nb-containing TiAl alloy

10.1016/j.matdes.2018.03.067

2018-03-29

The precipitation behaviors of βo(ω) phases are investigated in order to understand the effects of deformation on the microstructural stability during thermal exposure. Deformation can promote the precipitation of the βo(ω) phases not only at the lamellar bou...

Solution-liquid-solid growth of CuInTe2 nanowires as lithium-ion battery anodes
