Texture Analysis of Thin Titanium(TA1)Strip by Maximum-entropy Method

The Maximum-entropy Method(MEM)for determining the complete ODF(orientation distributionfunction),accompanied with the equal-volume partitioning technique for quantitative texture analysis,was firsttested in analysing the texture of a commercial purity titanium strip.The experimentally measured results indi-cate that the rolling planes of most grains in this sample are parallel to the{1010}and the{1210}with about~±10°spread while the rolling directions nearly distribute uniformly and their volume fractions are 19.46％and 18.70％ respectively.Besides,there are still two weaker texture components,(7526)[1544]and(1105)[2311],with 3.24％and 4.17％respectively.     

介质温度对耐高温铁素体不锈钢点蚀行为的影响

通过阳极动电位极化测试、电化学阻抗谱(EIS)测试及钝化膜电容测试等电化学腐蚀方法,研究了在不同温度的典型介质(NaCl质量分数为3.5％的溶液)中444铁素体不锈钢的耐点蚀行为及其影响规律.结果表明,随着介质温度的升高,444铁素体不锈钢的自腐蚀电位Ecorr和点蚀电位Ep均呈现降低趋势,而自腐蚀电流密度icorr增...
