Abstract: A modified mixed strengthening model was proposed for describing the yield strength of particle reinforced aluminum matrix composites. The strengthening mechanisms of the composites were analyzed... in the modified mixed strengthening model by introducing a distribution uniformity factor u and a cooperation coefficient fc, respectively. The results show that the modified mixed strengthening model can......
this gap, it is necessary to study the basic principle of evaluating the capacity of the plate straightener. In this work, the mechanics model describing the strengthening capacity was presented. To verify... of the incoming plate and the plastic ratio. The mechanics model describing the capacity of the machine was developed. The deviation of the straightening capacity curves was studied. Then, the presented model......
. Transmission electron microscopy was used to observe the precipitate distribution and to thus clarify strengthening mechanism. A new model was established to describe the strengthening of AA6082 by HFQ process in this novel forming technique. The material constants in the model were determined using a genetic algorithm tool. This strengthening model for AA6082 can precisely describe the relationship......

The microstructural development and strength predictions of the model... to predict evolution of radius and volume fraction of the strengthening particles. Then, strengthening model based on Orowan mechanism was established to predict yield strength. 2 Model The modeling......

Deformation behavior of SiC particle reinforced Al matrix composites based on EMA model CHENG Nan-pu(程南璞)1, 2, ZENG Su-min(曾苏民)1, 2, 3, YU Wen-bin(于文斌)1, 2, LIU Zhi-yi(刘志义)1, CHEN Zhi-qian(陈志谦)2... assumption(EMA) model. The particle size distribution naturally brings about the variation of matrix properties and the interfacial matrix failure due to the presence of SiC particles. The theoretical......
