Recent advances have enabled the production of nano‐grained metallic alloys with a thermally stable microstructure. Consequently, bulk samples and subsequent machining testing standardized test specimens is now real possibility. Therefore, for first time, authors report on in‐depth characterization machinability nanocrystalline materials. In particular, this study addresses feasibility to what extent, if any, microstructure altered due high stresses temperature incurred during machining....
Nickel and its alloys are useful in a range of applications, nickel foams have increased popularity for functional such as electrodes. Despite their versatility interest burgeoning technologies, there is only one well‐developed method producing porous commercially. This work introduces simple creating porosity Monel (70% Ni, 30% Cu) that results sub‐micron to micron‐scale pores grains. accomplished by oxide dispersions the metallic matrix then reducing those oxides at elevated temperature...
An oxide-dispersion-strengthened (ODS) nanostructured FeNiZr alloy was fabricated via high energy mechanical alloying, and subsequently consolidated by the field assisted sintering technique (FAST). A range of input parameters: Temperature, hold time pressure were evaluated in an effort to optimize response material. Improvements density, up 98.6% theoretical, observed with increasing consolidation temperature at cost decreasing hardness values resulting from microstructural coarsening....
Given their potential for significant property improvements relative to large grained counterparts, much work has been devoted the continued development of nanocrystalline metals. Despite these efforts, transition materials from lab bench actual applications blocked by inability produce scale parts that retain desired microstructures. Following a method proven stabilize nanosized grain structure temperatures approaching melting point given metal, US Army Research Laboratory (ARL) progressed...
