MATERIALS SCIENCE. VOLUME 2 PHASE TRANSFORMATION AND PROPERTIESSpasówka, EwaPolimery
Theβ→α phase transformation has been studied in SiC sintered with addition of boron and carbon by optical microscopy, and scanning and transmission electron microscopy. In the late stage of densification and during subsequent anneals, a feathers develop at the expense of theβ grains. They are...
Titanium dioxide, TiO2, is an important photocatalytic material that exists as two main polymorphs, anatase and rutile. The presence of either or both of these phases impacts on the photocatalytic performance of the material. The present work reviews the anatase to rutile phase transformation. The ...
Fig. 3.Chalcogenide phase change materials. (a) Ternary phase diagram of Ge–Sb–Te showing important pseudo-binary combination. Most frequently used (GeTe)x–(Sb2Te3)1-x compounds such as GST-326 and GST-225 are labeled in red. (b) The typical structural transformation in GST-225 when ...
The present paper deals with the mechanism operating in one of the three major transformation modes appearing in two-phase TiAl-based alloys: the formation of the so-called {gamma}/{alpha}{sub 2} lamellar structure. This microstructure, the most typical of the alloys of this category, results...
The transformation curve (TTT-curve) has been frequently used to determine the phase transformation under specific temperatures and times for ferrous materials, but no feasible transformation curves for graphite ductile iron with various chemical compositions have been developed to determine the specific ti...
- 《Materials Science Forum》 被引量: 3发表: 2001年 Application of Color Metallography on As-cast Al-Mg-Si-Cu-Mn Alloy during Heat Treatment Color etching was performed to characterize microstructure evolution and phase transformation on as-cast and homogenized Al-Mg-Si-Cu-Mn alloys. Initial ...
disordered semiconductors, silver iodide single crystals, and aluminum alloys. The structural aspects of phase transitions are also considered, along with the statistical mechanics of glass transition; thermal expansion and phase transitions in silica; phase transformation of Fe-Mn alloys induced by shock...
Experimental investigation on phase transformation of Cu-Ni-Si alloy melts during cooling Based on the experimental and calculational results, the phase transformation behaviour of Cu-8.33Ni-1.67Si melts during the cooling process was discussed, ... L Jia,H Xie,ZL Lu - 《Materials Science & ...
