Technical science defines a lot of different factors, that they may be cause of shorter cutting tool lifetime.
One of these materials is sintered carbide.
Testing properties of those materials is very important, because their properties may be different than properties defined in standards ISO.
Within this paper there were tested cutting materials made of sintered carbide (P20+TiN).
Standard ISO 3685 defines T-vc dependence in logarithmic scale how to linear dependence, that is for all cutting materials common.

Introduction Aluminides of iron and titanium are promising materials for the high-temperature use.
SEM-EDS was also applied for the chemical analysis of the oxidized materials.

Introduction In material science, fatigue fracture is the progressive and localised structural damage that occurs when a material is subjected to cyclic loading for a certain period [1].
In general the materials will have an unlimited life after 107 cycles [2].
