Residual welding stresses are a key parameter which needs to be controlled in order to minimize failures at the weld site.
The three main observed sources of stress are contraction stress, stress due to higher surface cooling and stress due to phase transformation. Continue reading →

The electrowinning process is a key method for precious metal recovery and can mean big business especially when processing gold plated components.
The gold is actually recovered from aurodicyanide solutions produced by the elution of loaded carbon and this is responsible for driving the resulting electrochemical reactions.

Lost foam casting is a small, but important part in the recent acceleration to drive technological improvement in industry.
In the automotive industry consumer demand is at its highest which mean materials technology needs to keep pace and with LFC it allows solid aluminum parts to be created to help drive weight and cost savings.

There are two main ways by which ferro-alloys are produced, by carbon combined with a suitable smelting process and metllo-thermic reduction with other metals.
The former procedure is normally associated with bulk operations whilst the latter is mainly used to focus on specialized high grade alloys with generally low carbon content.
