Dear MEMS collegues:

I am working on the laser forming  of metals, using laser to scan the
material to introduce
thermal stress in the material. It is very important to have the flow
stress datas, to
1. Improve of the design
2. Diagnostics during the manufacturing:
3. have better undertsnading of the material's microstructure change
during the manufacturing.

The temperature in the scanning path is in range of 400C---1500C,  flow
stress is in the range of
200MPa to 400MPa.

I am looking for some coorperation. Does anyone know the publications or
web adresses to extract these
informations ?
Thank you very match;
Best regards
