Abstract TIG welded marine grade AA5083-F/ER5356 and AA5083-F/ER5356+Sc joints were friction stir processed with a pin less FSP tool, to explore the impact of process parameters on mechanical metallurgical characteristics weldments enhance weld strength. The microstructure welds was observed using optical SEM subjected tests like toughness, tensile, microhardness fractography, evaluate strength...

The acquisition of fertilization capacity by sperm is regulated by intracellular pH (pH(i)), but the transport pathways that regulate pH(i) are not well understood. Lishko et al. (2010) now report that Hv1, the voltage-sensitive proton channel, is present in human sperm and is an important regulator of the functional maturation of sperm.

BACKGROUND The aim of this study was the characterization of mechanical properties of representative types of orthodontic wires employing instrumented indentation testing (IIT) according to ISO 14577. METHODS Segments were cut from ten wires. The first six are made of stainless steel (SS), two are made of Ni-Ti, and the last two are made of titanium molybdenum alloys (TMA). Then, the Martens ...
