“…Therefore, the sample is electrolytically polished to achieve a sharp tip, afterward the tip is etched with picric acid for 5 min to reveal GBs. To make sure that real GBs are identified and not only effects resulting from martensite needles transmission Kikuchi diffraction (TKD) is applied in combination with the last sharpening step with focused ion beam (FIB) …”

The science and technology of boron addition to heat‐treatable steels are explained. The aim is to address the following: How to add boron to steel (i.e., the manufacturing aspects of boron addition to steel)? What precautions are necessary when alloying boron to steel, in terms of composition (mainly nitrogen, aluminum, and titanium contents), processing and heat treatment (i.e., material and process robustness and reproducibility for a consistent steel quality)? Where does boron go in steel (i.e., the state of boron, interstitial or substitutional solute, precipitate or a complex with other alloying elements; as well as the location of boron, i.e., dissolved as a solute in the grain or segregated at the grain boundary)? Which characterization methods are suitable for the detection of the very small amounts of boron (<30 wt ppm) in heat‐treatable steels? What does boron do in steel (i.e., its effect on hardenability and mechanical properties, specifically impact toughness)? How does it do and what it does (i.e., the physical mechanism by which it influences the properties)? How much boron is really required to achieve the desired properties in heat‐treatable steels (i.e., recommendations for the optimum boron content)?

Intermetallic β‐Solidifying γ‐TiAl Based Alloys − From Fundamental Research to Application

et al. 2017

View full text Add to dashboard Cite

Intermetallic titanium aluminides based on the ordered g-TiAl phase have gained increasing interest as innovative high-temperature light-weight structural materials. They have found application in aerospace and automotive industries and are still subject of worldwide research and development activities. Their attractive properties perfectly match the engine manufacturers' demands. This review, bridges the gap from the development of the TNM alloy through structural characterization with sophisticated in and ex situ methods, engineering properties, manufacturing, and processing technologies to all aspects of application. Because one thing is clear, the material still has great potential.

“…Furthermore, NBD allows for identification of crystallographic phases, even on atom probe tips [35]. Babinsky et al recently demonstrated that transmission Kikuchi diffraction (TKD) can be employed to investigate grain orientations directly on AP tips [3]. This SEM-based orientation mapping technique was also recently demonstrated to show improved spatial resolution as compared to EBSD; 6-8 nm in a Ni sample [37].…”
