Coarse open celled aluminium foam produced by infiltration of sintered salt (FOAM-U-LIKE)
FOAM-U-LIKE (Foaming of aluminium metal using lightly interconnected kevelled elements) is a very inexpensive route for the production of coarse open celled foams. It allows a reasonable degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor. In this case, grains of 1-4mm diameter have been sintered at 600 degrees C for just 10 minutes, giving rise to lightly

Architecture's Unique Position Among the Disciplines : Puzzle-Making vs. Problem Solving
Most disciplines involved in the building process, i.e., programmers, space planners, and engineers work in what may be described as a problem solving mode. They state desired effects as explicit performance criteria before they initiate a decision process and test alternative solutions against those criteria until a fit is attained which falls within known probabilities of success. Architects, however are not problem solvers and they are not seeking explicit information when they design how bui

Fe, C 1.0 (wt%), hypereutectoid alloy
This secondary electron SEM image shows the cementite delineating prior austenite grain boundaries with a thin layer. The amount of proeutectoid phase is very low, with the majority of the area being taken by the pearlite eutectoid. Again each pearlite cell has a different orientation with the ferrite phase being selectively etched.
