..., and impregnation, meant to preserve pore structures and keep them open for analysis. The article compares and contrasts the microstructures of nearly 50 powder metal alloys, using them to illustrate the effect of consolidation and compaction methods as well as particle size, composition, and shape. It discusses...

... long periods of burial ( Ref 37 , 46 ). On high-tin bronzes (i.e., copper alloys containing 20 to 25% Sn), the patinas are often relatively smooth, and they preserve the detail and shape of an artifact, even after thousands of years of burial ( Ref 47 , 48 , 49 ). They can also be highly valued...
