http://www.sciencedirect.com/sci ... i/S1359646211005057 Influence of grain size and texture on Hall-Petch relationship for a magnesium alloy W. Yuana, S.K. Panigrahia, J.-Q. Sua and R.S. Mishra, a, a Center for Friction Stir Processing, Department of Materials Science & Engineering, Missouri University of Science and Technology, Rolla MO 65409, USA Received 8 July 2011; revised 29 August 2011; accepted 30 August 2011. Available online 1 September 2011. Abstract Friction stir processing was applied to a magnesium alloy to generate various grain sizes with same intense basal texture. Subsequent tensile deformation along two orthogonal directions by easy activation or inhibition of basal slip follows Hall-Petch relationship between yield stress and grain size in both directions. The Hall-Petch parameters are texture dependent. Easy activation of basal slip introduces lower values while inhibition of basal slip leads to higher values. The Hall-Petch parameters are interpreted by texture and microstructural factors. Keywords: Texture; Hall-Petch relationship; magnesium alloy; friction stir processing 這都可以??? |

僅僅個人的一些看法,說的不一定正確 一篇文章,有一個比較新的地方就可以了。從摘要看,這篇文章提出了在鎂合金中hall-patch公式中的參數(shù)與織構(gòu)有關(guān),我覺得這算個挺好的結(jié)果了。鎂合金的hall-patch系數(shù)本來就比較大,也就是說與其他金屬相比(如鋁合金)細(xì)晶對強(qiáng)度增加的貢獻(xiàn)更大,因此鎂合金細(xì)晶的研究還是很有意義的,而研究細(xì)晶,hall-patch公式肯定是繞不過去的。同時,作者用摩擦攪拌的方法制備了不同晶粒大小的強(qiáng)基面織構(gòu)鎂合金,我認(rèn)為方法還是值得借鑒的。 |
