Conclusions Composite Fe-NbC powder produced by HEM can be processed by PM techniques to obtain highdense cermet-type materials.
The microstructure of heat treated materials is more homogeneous than as-sintered materials and presents low porosity.

It is also suggested that a side grooving of 0.2 time thickness shows to work well for many materials.
To study the effect of various SG parameters on 3D blunted crack-front J-integral for CT specimens, all the FEMs were applied with the same materials properties.
The study of additional geometries and materials on J-integral will be investigated in the sequel.
