thermoelectric process in which heat energy of spark is used to remove material from the work piece. The machining process involves controlled erosion of electrically conducting material by the initiation of rapid and repetitive electrical spark discharges between the tool and workpiece separated by the dielectric medium. The present work is aimed at characterizing the electric discharge machin...

The age-hardening behavior of Fe−25.3Ni−1.7 Ti (wt pct) alloy both in undeformed specimens and in specimens cold deformed by 10 or 20 pct prior to aging was studied. The microstructural changes during aging were observed using transmission electron microscopy (TEM) and atom probe analysis and there were related to the mechanical properties as measured by microhardness and shear punch testing. A...

Currently, surface treatments lead to inducing a superficial layer of several nanometers up micrometer, which in some cases can be protective. In this experimental work, an oxide was generated under different atmospheres (CO2 and steam atmospheres) during the thermal aging treatment two maraging grades, 300 350. Afterwards, microstructural mechanically characterized by advanced characterization...
