Conclusions

  1. 1.

    We have established that the method of preparation and the test conditions may affect not only the strength of porefree materials but also the form of the strength/grain size relationship.

     
  2. 2.

    We have demonstrated experimentally that the strength of porous materials is proportional to d−n, where n=1/4 for unsintered materials and those sintered without additives, and n=1/2 for sintered materials containing additives of the eutectic type.
