This paper takes the ultra-fine grain AZ80 magnesium alloy multi-directionally forged as the research object. We observe its heating behavior at 673 K with an optical microscope, analyze the grain size distribution, and the change of average grain si... see more

A description of the improved mechanical properties obtained in ultra-fine-grained steels up to now will be presented in this paper, and some potential applications of these new generation steels will be described. In addition, the principle and implement... see more

Al0.4FeCrCo1.5NiTi0.3 high-entropy alloy (HEA) was prepared by mechanical alloying (MA) and spark plasma sintering (SPS), which were evaluated in this study by XRD and TEM. After SPS, the bulk alloy exhibited a structure with a dominant fcc phase, a minor... see more

It is known that the most effective way to improve mechanical properties of steels is by microstructural refinement. Iron and graphite powders mixture with hypoeutectoid composition were mechanically alloyed (MAed) and subsequently hot pressed (HPed) to p... see more

Equal channel angular pressing (ECAP) is one of the severe plastic deformation techniques which is widely used for producing metals with ultra-?ne-grained microstructures. In the present work the influence of number of pressing by route BC on gr... see more

With nano-scale technology and Moore's Law end, architecture advance serves as the principal means of achieving enhanced efficiency and scalability into the exascale era. Ironically, the field that has demonstrated the greatest leaps of technology in the ... see more

Objectives: To investigate the difference of application of core needle biopsy histology and fine needle aspiration cytology in cervical lymphadenopathy.Methods: A retrospective analysis was made on 80 patients with cervical lymphadenopathy admitted to Ba... see more

Location detection in social-media microtexts is an important natural language processing task for emergency-based contexts where locative references are identified in text data. Spatial information obtained from texts is essential to understand where an ... see more

ABSTRACTSoutheast Sulawesi is crosscutted by Lasolo Fault into two geological provinces: Tinondo and Hialu. Tinondo Geological Province is occupied largely by Ophiolite Complex in the northern part of Southeast Arm of Sulawesi. No study was conducted in r... see more
