细晶强化 (Fine Grain Strengthening) 细晶强化,是指通过晶粒粒度的细化来提高金属的强度,多晶体金属的晶粒边界通常是大角度晶界,相邻的不同取向的晶粒受力产生塑性变形时,部分施密特因子大的晶粒内位错源先开动,并沿一定晶面产生滑移和增值。滑移至晶界前的位错被晶界阻挡。这样一个晶粒的塑性变形就无法直接传播到相...

According to the described method, by combining the optimization of the components and inclusions with smelting, continuous casting and rolling improvement as well as an inclusion induced fine grain strengthening mechanism, the strength of the steel bar is improved, the amount of precious alloy ...
The yield strength of the alloy can be significantly enhanced by reducing the grain size. When the grain size measures 13 μm, the alloy can achieve a yield strength exceeding 900 MPa due to the combined impact of fine grain strengthening in the recrystallized microstructure and dislocation ...
Introduction The strengthening mechanism of second-phase particles in steel mainly includes precipitation strengthening and fine grain strengthening. At present, the research of adding ultra-fine particles into molten steel is few. By this way, the demand on the cleanliness of molten steel is not ...

The deformation kinetics are examined for "nanocrystalline" materials, whose grain dimensions are on the order of tens of nanometers and exceed the limitations of the Hall-Petch equation. In particular, literature data measured in pure tungsten is analyzed. This material was chosen, not only becaus...
