Electret behavior discovered in solder, specifically tin–silver

An electret is a permanent electric dipole exhibited by a material. This work provides the first report of the electret behavior of a solder, which is Sn–4Ag in the form of a fluxless unpoled wire of

Electric polarization and depolarization of solder, and their effects on electrical conduction

This work provides the first report of the effect of the dielectric behavior on the conduction behavior of solder. The lead-free solder studied contains 96 wt% tin and 4 wt% silver. The electric

Absorption-dominant radio-wave attenuation loss of metals and graphite

Absorption-dominant radio-wave (0.2–2.0 GHz) attenuation loss is comparatively reported for materials of high electrical conductivity, namely metals (aluminum and steel) and graphite. These materials

Radio-wave absorption by aluminum and its dependence on the absorption distance

The absorption of radio wave is relevant to electromagnetic interference (EMI) shielding and low observability. The effect of the absorption distance much above the calculated skin depth on the

The performance and reliability of soldered joints are important for electronic packaging. This work provides the first observation of piezoelectricity (generating electric field and capacitance),

Preferred lattice misorientations in rolled aluminium: tracking experiments and crystal plasticity simulations

The microstructural heterogeneities developed in the grains of hot deformed Al have been quantified by applying the microtexture tracking technique to hot plane strain compressed Al-0.1%Mn. By

Crystal preferential orientation of Al-1.0%Si alloy in continuous unidirectional solidification process

Al-1.0%Si alloy rods containing unidirectional microstructures were fabricated by continuous unidirectional solidification (CUS) process. The crystal growth orientation evolution of Al-1.0%Si alloy

Aluminum Metal-Matrix Composites for Automotive Applications: Tribological Considerations

Aluminum alloys possess a number of mechanical and physical properties that make them attractive for automotive applications, but they exhibit extremely poor resistance to seizure and galling.

Engineering wear-resistant surfaces in automotive aluminum

Inadequate wear resistance and low seizure loads prevent the direct use of aluminum alloys in automotive parts subject to intensive friction combined with high thermal and mechanical loading, such as

Structure and Properties of High-Strength Aluminum Alloy 1933 Rolled Plates

Results are given for metallographic and x-ray diffraction analysis of the structure, degree of recrystallization, and preferred crystallographic orientations, and also mechanical and corrosion
