peritecticreaction

peritectic reaction occurs when a slowly cooled alloy ex. Fe-Ni phase diagram δ phase – Ni in BCC-Fe γ phase – Ni in FCC-Fe. Fe-4.3 wt% Ni passes through ...

由 H Nassar 著作 · 2009 · 被引用 9 次 — This thesis deals with peritectic reactions and transformations that occur during the solidification of many alloys. Peritectics are believed to be a major ...

Peritectic systems generally occur when the melting points of the pure components are very different. The peritectic temperature then lies between the melting ...

由 FC Campbell 著作 · 2012 · 被引用 3 次 — As the peritectic reaction continues, the α layer gets thicker and the reaction slows down even more. Unless the cooling rate is very slow, a ...

A peritectic reaction occurs if the average composition of the alloy crosses this line during either slow heating or cooling. It can be represented by the ...

Similar to the eutectic reaction, the peritectic reaction involves a liquid phase and two solid phases, however in the peritectic reaction the composition of ...
