This study investigated the precipitation
strengthening of the binary Al-0.14wt% Sc,
0.16% Ti alloy system. Ingots of Al-2.1wt% Sc
and Al-4.68wt% Ti were melted together, and
the nucleation, growth, and coarsening of
precipitates were analyzed. The microstructural
evolution of the nanoscale L12 precipitates
phase was examined with Vickers
microhardness testing,...
The effects of Ru, W, and Re on the temporal
evolution of the gamma prime precipitates in
a Ni-Cr-Al alloy were investigated by threedimensional
atom probe (3DAP) microscopy.
The spatial distribution of the gamma prime
precipitates in a model Ni-8.5Cr-10Al alloy
was investigated using atomic force
microscopy (AFM). We reported...
Fullerene and inorganic fullerene-like nanotubes
are molecules with the unique geometry
of a single layer or multiple layers of a bulk
material oriented in a tube. These molecules
have novel mechanical properties and great
potential in experimental systems for nanotechnology
and nanodevices. The threedimensional
atom-probe (3DAP) microscope
is an atomic...
