Cu-MgO Composites

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

Semi-Solid Rheocasting of Alumina Alloys: Part One

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

Twin Roll Casting of Mg Alloys

The twin roll casting method offers huge time and cost savings in comparison to traditional processes as it focusses on creating strip materials directly from liquid alloys.
Through the study of twin rolled magnesium microstructures it can be clearly seen that the finished product structure is uniform, significantly refined, and almost equiaxed throughout the cross section.
