... Abstract Lakes in zinc die castings are areas encompassed by irregular lines or waves on flat or slightly contoured surfaces which are intended to look uniform. The laked areas have to be removed by polishing before the castings can be plated. This adds considerably to the overall cost...

Figure 12 shows an example of ion-nitrided hot work die steel with a brittle white-etching iron nitride surface layer that is quite visible when mounted in Epomet resin but would probably be very hard...

...). Other coarse-grained regions were located 90┬░ circumferentially from the cracked areas. It was concluded that the pipes had been manufactured by extrusion through a bridged die, and that the extreme grain growth had resulted from the heat and strain of welding in the die. Coarse grains mean less...

In dies, common causes of galling are stretching sheet metal beyond practical limits, tool fitting with poor alignment or insufficient die clearance for the given sheet thickness, wrinkles, the use of galling-susceptible tool...
