Preface
This volume of Diffusion Foundations is devoted to high-tech materials such as elemental and compound semiconductors (chapters 1 and 2) and high-entropy alloys (Chapters 3 and 4).
Mehrer The two volumes of Diffusion Foundations with the titles Diffusion in High-tech Materials and Diffusion and Thermal Transport in Bulk and Nano-materials are dedicated to the memory of Professor Dr.
The diffusion community has lost a person with great merits in diffusion science.
In his group, about 27 PhD and master students performed diffusion studies in various materials and finished their thesis.
Nico published 165 papers in peer-reviewed international journals and scientific articles in several books before he retired in 2015.

It is well known that materials with nanostructures exhibit remarkable and technologically attractive properties.
In order to obtain nanostructured materials one way is to use nano-scaled powders and another is to obtain metastable structures [2,3] which transform to nanostructured material after heat treatment.

When the power is large enough, the scanned coated sand will be invalidated and couldn’t be cured, which will form a dividing surface between the extraneous materials and the objective part.
After consolidation, the coated sand mold can be finally got by removing the extraneous materials out of the dividing surface.
The material used in PIRP is powder.
The accuracy and efficiency could be greatly improved, for the layer thinkness is adjustable according to the shape of part. 3) Various materials are available for PIRP.
