The purpose of these plates is to allow a higher design loading of the main columns between the turbine building buttresses and the overhead crane rail. The plates are not subject to any calculated stresses, but provide extra resistance to buckling...

... systems. Most metals, including iron, copper, nickel, aluminum, and their alloys, are more or less susceptible to damage ( Ref 1 , 2 , 3 ). Only titanium and its alloys appear to be generally resistant ( Ref 4 ). This review focuses initially on the mechanisms of microbially induced or influenced...

... in service. A simple method of eliminating hydrogen embrittlement in the 17-4 PH bolts is to age them an additional 1hr at 1,000 F. Heat treatments which promote toughness also add resistance to hydrogen embrittlement. The almost linear relationship between hardness and toughness is shown in Fig. 3...
