This article is an atlas of fractographs that helps in understanding the causes and mechanisms of fracture of austenitic stainless steels and in identifying and interpreting the morphology of fracture surfaces. The fractographs illustrate the following: fatigue-crack fracture, rock candy fracture, cleavage fracture, brittle fracture, high-cycle fatigue fracture, fatigue striations, hydrogen-embrittlement failure, creep crack propagation, fatigue crack nucleation, intergranular creep fracture, torsional overload fracture, stress-corrosion cracking, and grain-boundary damage of these steels. The austenitic stainless steel components include spring wires, preheater-reactor slurry transfer lines and gas lines of coal-liquefaction pilot plants, oil feed tubes and suction couch rolls of paper machines, cortical screws and compression hip screws of orthopedic implants, and Jewett nails.

Alloy 5056 can be used for nails and for redrawing rod to make wire. This datasheet provides information on key alloy metallurgy, processing effects on physical and mechanical properties, and fabrication characteristics of this 5xxx series alloy.

This article compares and contrasts mechanical joining techniques used in the manufacture of aluminum assemblies, including seaming, swaging, flanging, crimping, clinching, dimpling, interference and snap fits, and interlocking joints. It provides basic illustrations of the various methods and summarizes the advantages and disadvantages of each. The article also discusses the use of staples, nails, rivets, and threaded fasteners and provides relevant property and performance data.

This article is an atlas of fractographs that helps in understanding the causes and mechanisms of fracture of cobalt alloys (cast Vitallium and cast ASTM F75 alloys) and in identifying and interpreting the morphology of fracture surfaces. The fractographs illustrate the fatigue fracture, microcrack, and stair-step fracture surface of these alloys.
