In general, there are three general ways to prevent creep in metal. One way is to use higher melting point metals, the second way is to use materials with greater grain size and the third way is to use alloying. Body-centered cubic (BCC) metals are less creep resistant in high temperatures.
Q. What is the difference between capillarity and porosity?
Capillarity Porosity represents the STORAGE CAPACITY of the geologic material and is the ratio of the volume of holes/openings to the total volume of the material. (Some people call openings as VOIDS in textbooks.) Porosity = (volume of holes in material) / (total volume of material).

Q. What determines porosity?
Porosity is the percentage of void space in a rock. Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage.
Q. Why does sand have a low porosity?
For instance, small particles such as clays are able to compact more closely together, reducing the amount of porosity. However, larger particles such as sand and gravel will have more spaces available between them. Round particles compacted together will have more spaces than elongated grains that stack more tightly.
Q. What sediment can hold the most water?

Q. What is creep damage?
Creep damage occurs in metals and alloys after prolonged exposure to stress at elevated temperatures. Creep damage is manifested by the formation and growth of creep voids or cavities within the microstructure of the material.
Q. What is creep effect?
Creep is a type of metal deformation that occurs at stresses below the yield strength of a metal, generally at elevated temperatures. One of the most important attributes of any metal is its yield strength because it defines the stress at which metal begins to plastically deform.
