內容簡介：
These pages describe a new technique to directly observe the solidification (freezing) process in metal alloys in real-time by using x-rays. In the following pages you will find: images and explanations of what we can see, how it's done, and what we plan. Our method of X-ray Microscopy uses a special microfocus x-ray source to create images of the solid-liquid interface during solidification under controlled conditions. Features having dimensions below ten micrometers are being observed and studied in real-time. The information from this fundamental research is used to produce stronger alloys and composite materials. Every experiment is an exploration into previously unseen worlds.
