cause stronger local thermal inconsistency (LTI) and remarkably increase the microdefects in the material, which may markedly degrade the macroscopic mechanical properties of the material.
Key words: brass H62; pre-loaded stress; heating rate; failure temperature; local thermal inconsistency
were also observed. It is shown that the high heating-rate may cause stronger local thermal inconsistency, which remarkably increases the microdefects and reduces the macroscopic mechanical properties of the material.
Key words: magnesium alloy AZ31; pre-loaded stress; heating rate; failure temperature; local thermal inconsistency
1 Introduction
It is known that the high and rapid increase......Effect of heating-rate on failure temperature of pre-loaded magnesium alloy

sand mould with chill can strongly decrease the SDAS. Reduced SDAS close to the mould bottom because of chilling was obtained. Pressure seems to have no apparent effect on the SDAS. In order to obtain casts with UTS ≥320 MPa, SDAS must be less than 55 μm, which means a local cooling rate VL≥0.23 ℃ /s.关键词:......
-view interactive behavior recognition method based on local self-similarity descriptors and graph shared multi-task learning. First, we proposed the composite interactive feature representation which encodes both the spatial distribution of local motion of interest points and their contexts. Furthermore, local self-similarity descriptor represented by temporal-pyramid bag of words (BOW......
, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China) Abstract: The purpose was to improve the efficiency of local density and delta distance based clustering (DDC) by using the quantum computation, which was characterized by the great performance of the parallel computation. First, the quantum counting algorithm was developed to accelerate the processing of local density......
