Peritectic Melting
Peritectic melting is the reverse process of the peritectic reaction, where a solid phase dissolves on heating into another solid phase and a liquid.
Physical-Chemical Mechanism of Action
During peritectic melting, a solid metal phase dissolves upon heating into another solid phase and a liquid metal phase. This process is a special example of phase transformation, in which the composition of the metals is changed during melting.
Metallurgical Relevance & Risks in Welding
Peritectic melting can cause problems if it is not properly controlled. For example, uncontrolled phase transformation can lead to non-uniformity in the composition and structure of the metal, which can impair mechanical properties. In addition, it can cause deformation or damage to the components.
Workshop Practice & Action Guidelines
To successfully carry out peritectic melting, temperatures and times must be precisely controlled. It is important that the metal is heated in a protected environment to avoid deformation. The exact temperature and time depend on the specific metal alloy and should always follow the manufacturer's instructions.
