Low superheat casting is similar to the better known SSM technique which can be applied primarily to produce billets with a low cost advantage.
In the LSC process, the alloy is rapidly solidified and cast with a low pouring temperature which is typically just above the liquidus temperature. Continue reading
Additive manufacturing is a relatively recent manufacturing method which has become a key area of interest in multiple industrial sectors.
Deriving from CAD models the process can be used to create solid yet highly complex parts and pushes towards a tool-less manufacturing environment meaning improved quality and better efficiency in many cases. Continue reading
Metal matrix composites reinforced with ceramic particles can be interesting for a range of applications due to their strength performance at high temperatures and a relatively low thermal expansion potential.
Manufacturing of Cu-MgO composites critically requires that the raw materials have a very high level of purity (99.5-99.9%) to achieve the desired manufacturing results. Continue reading
Vacuum die casted materials have many applications in the automotive industry as well as a number of other commercial industrial sectors.
The main benefits of VDC as opposed to other more traditional methods of casting include a higher quality surface finish, improved mechanical properties and an overall better finished product stability. Continue reading
Spark Plasma Sintering (SPS) is a sintering technique which is well matched to mechanically milled materials such as tool steels due to its low temperature and short cycle time.
Tool steels have been specifically manufactured to exhibit exceptionally high strain hardening, a characteristic which can be undone by high temperature sintering processes such as hot isostatic pressing. Continue reading
Investigations into the superplasticity possibilities of aluminums can lead to many potential gains in finding lighter yet capable materials in terms of strength performance.
This article covers the high-temperature deformation behavior of 5083 at different annealing temperatures and yields some interesting conclusions. Continue reading
Aluminum is well established at the front of the pack with regards to providing the technological answer to the increasing challenges of light weighting whilst maintaining integrity of the material for the desired applications.
Semi solid rheocasting is a development within the casting sector which enables improved quality in die casting without increasing cost. Continue reading
Austenitic steels may undergo microstructural changes during short- or long-term exposure to high temperature. In the case of longer ageing times, other precipitates such as intermetallic phases are formed, which are usually accompanied by dissolution of carbides.
The intermetallic precipitations are of great interest not only because they exert influence on the mechanical properties but also because of their strong effect on the corrosive properties.
