Powder Metallurgy (PM) is a forming technology that uses metallic (sometimes also in conjunction with ceramic) powders to develop parts, most of the time through thermal process called sintering, which never reaches melting point principal component alloy [...]

In the last decade, titanium metal matrix composites (TMCs) have received considerable attention thanks to their interesting properties as a consequence of the clear interface between the matrix and the reinforcing phases formed. In this work, TMCs with 30 vol % of B₄C are consolidated by hot pressing. This technique is a powder metallurgy rapid process. Incorporation of the intermetallic to th...

Stereocomplexation between enantiomeric poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA) provides an avenue to greatly enhance performance of eco-friendly polylactide (PLA). Unfortunately, although the manufacturing of semicrystalline polymers generally involves melt processing, it is still hugely challenging to create high-performance stereocomplexed polylactide (sc-PLA) products from melt-pr...

In this study, in situ Al2O3-reinforced Ti3Al composite was fabricated after 8 h of milling and sintering at 850 °C. A mixture TiO2 Al powders were mechanically milled a planetary mill, cold-compacted sintered under protected argon atmosphere. The microstructure microhardness the Al2O3 embedded matrix both room elevated temperature has been reported. obtained results showed that Ti3Al/Al2O3 suc...

In Powder Metallurgy the knowledge of the mechanisms governing the deformation behaviour of the material during its processing is in an initial stage due to the lack of an elasto-plastic model that could explain the mechanical behaviour, specially when the initial stage of powder die compaction is the one to be considered. For this reason geological models such as Cam-clay and Cap [1, 2, 3, 4] ...

Abstract For powder metallurgy processing, the sintering stage, i.e. heat treatment of a compact below melting point -at least- major component, is decisive for establishing microstructure and properties. Thorough studying chemical metallurgical processes occurring during essential attaining optimal product properties, has therefore been focus investigations many decades. Thermoanalytical techn...

The chemistry surrounding the pyrolysis of N,NЈ-ethylenebisstearimide (EBS) compacted with iron powder is described for the first time. Heat treatment is carried out in a 5 vol pct hydrogen atmosphere (balance nitrogen) over the 100 °C to 850 °C range. The exhaust from the furnace is monitored by Fourier transform infrared and dispersive ultraviolet absorption spectroscopy; condensable material...
