... should reveal whether a stress concentrator might have contributed to failure. The metallographic specimens should disclose the existence of any improper microstructures, such as decarburized layers, carburized skin, alloy segregation, high-strength martensite in the HAZ, and inadequate weld penetration...

... and decarburization. Both of these definitions apply equally well to a casting or a weldment. Proper selection of casting process, alloy selection, part and mold design, solidification control, and grain refinement minimize hot cracking problems. Hot strength (resistance to cracking at solidification temperature...

... method is to increase the thermal gradient (often accomplished by increasing the solidification rate), which decreases the length of the mushy zone. This technique can be limited by alloy and mold thermal properties and by casting geometry, that is, the design of the casting. The fatigue strength...

... analysis revealed that the cast alloy 400 coupling had a silicon content of 1.97%, whereas the wrought alloy 400 piping had a silicon content of 0.10%. Castings of high-silicon alloy 400 generally have poor weldability and are often hot short, or sensitive to cracking in the weld HAZ. Fissures in the cast...
