This can be achieved by adding binary and ternary Al compounds such as AlN or Ti2AlC, which form aluminides with the metals of the binder phase.
This diagram shows that Ti(C,N) can be even more sub-stoichiometric than the binary compounds.
(b) Heat conductivity of TiC- and Ti(C,N) based compounds with addition of W, Nb and Ta as well as the influence of small Cr and V additions [43].
Similar observations were made for Ca compounds.
These are multiplied by the fact that the hard-phase powders show often a complete solid solubility and can be alloyed with each other to end up with a very large number of compounds that can be employed in the starting formulation.

In this context, the aim of this study is to develop ceramic tools with extended area of technological applications, including operations of interrupted cutting of hardened steels.
The generalized ideas of such mechanisms will allow solving successfully a highly complex scientific and technical challenge to connect dissimilar materials, such as "carbide-ceramic", "ceramic-refractory transition metal compounds", and other types.
The extensive research was carried out to develop the technology of producing HGC-ceramics with ceramic layer based on A1203, A1203-AlN, Si3N4, Si3N4-AlN formed on substrates of carbide WC-TaC-Co and subsequent application of nano-structured multilayer composite multi-component coatings based on systems of nitride compounds of refractory metals IV (Ti, Zr) and VI (Cr) of the Periodic Table doped Al and Si.

Some are solids like layer lattice compounds (graphite, MoS2), non-reactive coatings (mineral salt, polymers) and conversion coatings (zinc phosphate).
Experimental observations aim to identify the kind of surface defect that occurs (galling, scratch, grain debonding, etc.).
The numerical simulation aims to quantify the damage occurring in the vicinity of the defect.

This study aims to investigate the effect of cross-sectional pore shapes on the effective Young's modulus (EYM) of LTPMs.
According to Nakajima [1], his techniques can produce not only metals and alloys but also inter metallic compounds, semiconductors, and ceramics.
Conclusions The aim of this study was to investigate the pore shape effect on Young’s modulus of lotus-type porous materials with pores orientation perpendicular to the tensile direction.

This nano-concept is highly relevant for rubber compounds since their
application requires filler reinforcement [4-14].
Carbon black is an excellent reinforcement owing to its strong interaction with rubbers, but its presence especially at high loading often decreases the processability of rubber compounds.
Polyamide 66/SEBS-g-M alloys and their nanocomposites were prepared by melt compounding using a twin screw extruder.
Morphological investigations with different methods show pseudo-one-phase type morphology for these prepared alloys at all percentage of rubber.
The reduced modulus and strength of alloys with functional rubber addition was counteracted by incorporation of organoclay without significant negative effects on the impact strength.

Binary alloys of W–Si showed good self-passivation properties by forming a SiO2 film at the surface.
Beryllium is a particularly reactive material; when bonded to copper, brittle intermetallic compounds, such as BeCu, Be2Cu, may form.
TiNx coatings were also used as a wetting promoter for the brazing alloy, improving the infiltration of filler alloy into the pores of CFC and reducing the formation of detrimental intermetallic compounds [43].
This concerns particularly the Cu-based alloys for heat sinks.
Al2O3, Y2O3 and Er2O3 have similar CTE to V alloys, whereas the difference is larger for AlN.

This is the aim of this work.
Within the range of 1,100-1,200 оС, distillation was noted to be retarded as zinc compounds had already been reduced to almost 95-97%, and reaction surface approached zero.
Pelletizing of the zinc-containing charge material was carried out at the non-ferrous alloy production plant (Verkh-Neyvinsk) in a disk-type nodulizer.
