10.3.3.1 Static Compression Test Results
All of the quasi static compression tests were carried out under the laboratory conditions to evaluate the mechanical behaviour
of these composites produced with sinter + forging processes at 680
C through the powder metallurgy. Figure 10.4 shows all
of the static compression test results obtained on the four compositions containing different fine ceramic reinforcements as
indicate for each graphic.
All the compression test results obtained for the combined method sintered + forging process were compared depending on
the ceramic reinforcements. These values are mean values obtained from 3 to 4 tests for each composition. Standard deviation
is variable around Æ35 MPa. One may observe that the specimens containing TiB 2 and the specimens containing both of TiB 2
and B 4 C gives higher resistance regarding to the specimens containing alone TiC and B 4 C.
Toughness values of these composites seems strongly depend on the type and amount of fine ceramic particles. As
indicated in the former section, sinter +forging can give a sound microstructure without microporous and help to diffusion
bonding mechanism. For this reason, this process can be an efficient and economic process regarding to the other processes for
the manufacturing of the new composite families in practical point of view.
10.3.3.2 Low Velocity or Dynamic Compression (Drop Weight) Test Results
Low velocity impact (drop weight) tests have performed for four composite specimens containing fine ceramic powders as
presented in the Fig. 10.5 (a) TiB 2 , (b) B 4 C and (c) TiB 2 + B 4 C and also (d) TiC respectively. These values have been
evaluated the response of theses composites under the dynamic loading conditions a series of impact tests were performed at
