In wet ULES the use of additional h

In wet ULES the use of additional heating might contribute to the drying of these grain boundaries. Further work should be dedicated to understanding the relationship between the nature of grain boundaries (i.e. crystalline or amorphous), their thickness and processing parameters (pressure application, temperature, heating and cooling rates) on the grain boundary characteristics. The nature of grain boundaries in samples made by wet ULES can be distinctly different to those processed by conventional means.
