Effect Of Hot Pressing On The Electrochemical Properties Of Ti-Ni Alloy

Archives of Metallurgy and Materials, 2015
Ti2Ni alloy pellets were produced by mechanical alloying and hot pressing at 750°C for 0.5 h in vacuum. X-ray diffraction analysis showed that, after 8 h of milling, a starting mixture of elements mostly decomposed into an amorphous phase.

Reliability of electrochemical noise measurements: Results of round-robin testing on electrochemical noise [PDF]

Electrochimica Acta, 2014
Sixteen laboratories have performed electrochemical noise (EN) measurements based on two systems. The first uses a series of dummy cells consisting of a "star" arrangement of resistors in order to validate the EN measurement equipment and determine its baseline noise performance, while the second system, based on a previous round-robin in the ...
