...change in dimensions, so if dimensional stability is important a “stabilising” heat treatment is required, which also relieves stresses. Design: Die design is extremely important, and bad die design is the cause of most of the problems in low pressure die casting. The high die temperatures necessary to prevent premature chilling result in less massive dies than for...

Laser surface treatment

...changes to the atoms in the lattice of the material (austenite). As the beam moves away, to another spot on the surface, the heated area is rapidly cooled by the surrounding metal (self-quenching). This rapid cooling stops the lattice from returning to its original arrangement, resulting in a very hard surface structure (martensite). For cladding, the high temperature of...
