Penetrating morphologies at the growth front of abnormally-growing Goss grains in Fe–3%Si steel was examined in view of the possibility that they are the two-dimensional section of the solid-state wetting (SSW) along the triple junction line. To ob

Evolution of abnormally growing Goss grains in Fe–3%Si steel was observed time sequentially by electron backscattering diffraction (EBSD). For example, some specimens were heated at 1080 °C for 5 min, then cooled, polished and observed by EBSD, wh

In order to study the effect of the uniaxial stress on the development of a cube-on-face texture, two sheet samples were heat treated with different positions to have a different self-load, resulting in a different stress. One specimen was heat treat

When any sample is heat treated, it is normally placed on a supporting material. Such physical contact is not expected to affect the microstructure evolution of the sample. In this study, however, the physical contact between Fe-1%Si sheet and the Al

The refining effect of electron beam melting (EBM) during the additive manufacturing of Ti products was studied by comparing unused Grade-2 commercially pure (CP) Ti powder to an equivalent powder that had been recycled 50 times. The pre-heating and

If the phase transformation from γ to α is properly controlled in silicon steel, the cube texture is known to be produced. Two sheet samples of Fe-2 wt%Si-1 wt%Ni and Fe-3 wt%Si-2.5 wt%Ni were heated to 1100 °C, held for 2 h and then cooled. The i

When any specimen undergoes a heat treatment, it should be in contact with a supporting material. After testing Al2O3, quartz, tungsten and nickel as a supporting material of Fe-1wt%Si during heat treatment, we found out that the cube-on-face texture
