Abstract The nanometer-scale (nano-scale) microstructural evolution in an additively manufactured Re-free Ni-based superalloy, with single crystal compositions, is investigated through field emission scanning electron microscopy, transmission and atom probe tomography. We find that nano-scale primary ?? precipitation occurs the fine as-built microstructure, leading to exceptional microhardness ...

Kodak fine grain positive photographic emulsion has characteristics of speed, contrast, and grain size favorable for recording the low contrast electron images Of thin-sectioned biological material. In addition, the rendition of detail by this emulsion appears to be of superior quality to that obtained on conventional lantern slide emulsions. By special order, Eastman Kodak provides fine grain ...

A new ultra-high strength steel with a fully austenitic microstructure and twinning-induced plasticity (TWIP) effect has been developed. TWIP gives this good combination of high over 1000 MPa ductility 35%. This chromium content, which increases its corrosion resistance. By combining cold rolling annealing, the achieved very fine an average grain diameter 2.85 µm. could be used for structural a...

Instruction–level multithreading is an architectural approach to tolerating long–latency memory accesses and synchronization delays in distributed–memory systems. The paper presents a timed Petri net model of a fine–grain multithreaded distributed–memory multiprocessor system at the instruction execution level, and illustrates performance analysis by results obtained from simulation of the deri...

Symmetric multiprocessors (SMPs) connected with low-latency networks provide attractive building blocks for software distributed shared memory systems. Two distinct approaches have been used: the fine-grain approach that instruments application loads and stores to support a small coherence granularity, and the coarse-grain approach based on virtual memory hardware that provides coherence at a p...
