Ageing of nanodiamond powder: Physical characterization of the material

Structure, phase content and mechanical properties of aluminium with hard particles after shock-wave compaction

“…Microdistortion value has increased after adding hard particles. These values match with estimates made for metal powders [8] and make it possible to estimate stored energy [15]. As it can be seen from the table this energy increases when high-modulus particles are added.…”

“…Compaction of Al powder as well as its mixtures with n-diamond [7][8][9] and alumina [4,13] (10 wt% of each) was investigated in the framework of this research. Investigation of such compositions along with practical use for production of particle-reinforced composite materials will make it possible to study influence of high-modulus components on Al compaction process.…”

“…At the same time this method of aluminum powder compaction makes it possible to change the type and quantity of reinforcement material, e.g. aluminum oxide nanoparticles, high-modulus carbon particles in the form of nanodiamonds (further n-diamonds) [7][8][9] etc. This enables creation of materials with desired properties.…”

Physico-Mechanical and Electrical Properties of Aluminum-Based Composite Materials with Carbon Nanoparticles

“…can be used as reinforcing particles. A relevant method of such reinforcement consists in embedding of high-modulus detonation nanodiamonds [2,3] with nanocrystalline structure into the soft Al matrix. Unlike oxides, carbides and others which may change their structure due to interaction with the matrix, such particles remain stable at high temperatures (up to 1000°С according to [3]) and can stabilize mechanical and physical properties of alloys in a wide range of temperatures.…”

It is known that direct embedding of refractory particles (especially nanosized ones) into liquid metal is not possible due to the fact that they are prone to agglomeration and flotation caused by their low wettability by liquid metal.…”
