Each material is tested in flowing LBE for 200h, 400h and 600h. The sections below describe 
1] each material and its behavior in this environment in details. The SEM/EDX is done on each 
sample and the oxide layer thickness measurement results are given in Table 2. WDX and 
nano indentation are only done on the 600h exposed samples because the appearance in 
' Fe SEM/EDX is the same and only the thickness is different. XPS is only done on the 600h
