intergranular in a sentence
Examples
- While the intergranular failure problems noted above are sometimes severe, they are rarely the cause of major service failures ( in structural steels, for example ), as suitable safety margins are included in the designs.
- An example of such texture, related to fractioned crystallization, is intergranular ( also known as intercumulus ) textures that develop wherever a mineral crystallizes later than the surrounding matrix, hence filling the left-over interstitial space.
- The principle of effective stress, introduced by Karl Terzaghi, states that the effective stress " ? "'( i . e ., the average intergranular stress between solid particles ) may be calculated by a simple subtraction of the pore pressure from the total stress:
- Perhaps the greater concern is that with the development of new technologies and materials with new and more extensive mechanical property requirements, and with the increasing impurity contents as a result of the increased recycling of materials, we may see intergranular failure in materials and situations not seen currently.
- In the SiC / Al 2 O 3 system, for example, it is widely known and accepted that the addition of SiC particles to the Al 2 O 3 matrix results in a change of failure mechanism from intergranular ( between grains ) to intragranular ( within grains ) fracture.
- Putting aside some of the well known facts about deposit phosphorus vs various properties, i . e . hardness or corrosion resistance that we will cover a bit later, deposits with a high degree of amorphous composition are free of grain boundaries, which typically act as sites for intergranular corrosion commonly encountered in crystalline deposits.
- Furthermore, results indicate that microscopic pores in sintered ceramic nanomaterials, mainly trapped at the junctions of microcrystalline grains, cause light to scatter and prevented true transparency . it has been observed that the total volume fraction of these nanoscale pores ( both intergranular and intragranular porosity ) must be less than 1 % for high-quality optical transmission.
- High-strength aluminium alloys such as the Duralumin-type alloys ( Al-Cu ) which depend upon precipitated phases for strengthening are susceptible to intergranular corrosion following sensitization at temperatures of about 120 �C . Nickel-rich alloys such as Inconel 600 and Incoloy 800 show similar susceptibility . steam generators, or as a result of subsequent welding of the formed structure.
