Effect of the cold deformation regime on microstructure and mechanical properties of AISI 301LN stainless steel

引用

Baosteel Technical Research 2014年第3期8卷 18-26页

作者： huang junxia YE Xiaoning GU Jiaqing Research Institute Baoshan Iron & Steel Co.Ltd.

This study analyzed the effect of cold-rolling reduction （in a wide range of 10% - 80% ） and subsequent annealing on the microstructure and mechanical properties of AISI 301LN stainless steel. Results indicated the formation of shear bands and nucleation of strain-induced α＇-martensite at their intersections. The volume fraction of α＇-martensite increased with increase in cold-rolling reduction by the continuous growth of embryos. This, in turn,resulted in an increase in yield and tensile strengths. The reversion of α＇-martensite to austenite occurred after subsequent annealing. The observed variation in the grain size of reversed austenite can be related to the annealing regime. A good combination of strength and ductility can be obtained upon annealing at 650 ℃ for 30 min. The effect of grain size on yield strength conformed to the Hall-Petch relationship in the entire range of our analysis.

肺癌是全球第六大死因,也是恶性肿瘤的主要死因之一,非小细胞肺癌(non-small cell lung cancer,NSCLC)是其最常见的类型。表皮生长因子受体(epidermal growth factor receptor,EGFR)基因突变是NSCLC的常见突变之一。针对EGFR基因突变的晚期NSCLC患者,使用EGFR-酪氨酸激酶抑制剂(EGFR-tyrosine kinase inhibitors,EGFRTKIs)如吉非替尼、阿法替尼、奥希替尼等靶向治疗已经成为许多指南推荐的一线治疗方案,但许多患者在用药约1年左右便发生获得性耐药。出现获得性耐药的患者会比普通患者更早出现疾病进展,对患者的预后造成重大影响。目前对于发生了获得性耐药的患者主要的治疗方式为针对耐药突变进行新的靶点抑制,如发生了T790M突变的患者对第一、第二代药物(如吉非替尼、阿法替尼等)产生耐药,可以使用第三代药物(奥希替尼或阿美替尼)进行治疗,通过这种治疗方式可延缓病情进展。因此,耐药机制的研究及耐药患者的治疗是必不可少的。本文主要就EGFR突变NSCLC患者的靶向治疗及其耐药机制进行综述,以期为EGFR-TKIs的临床应用提供参考。

具有全珠光体组织的65Mn钢在650℃以C方式等径弯曲通道变形(ECAP)后,珠光体组织中的渗碳体片层以周期性的弯曲变形、周期性的剪切变形、剪切断裂等形式协调ECAP的强烈塑性变形. 渗碳体表现出很强的塑性变形能力,在其内部导入了大量的晶体缺陷,为渗碳体的球化打下了能量基础.变形五道次后,片层状的珠光体组织演变成了超细的渗碳体颗粒均匀分布于铁索体基体的组织.铁索体基体为均匀的等轴晶,平均晶粒大小为-0.3μm.渗碳体的球化可能以两种机制进行:破碎渗碳体片的非均匀长大(Ostwald熟化)和细小球状渗碳体颗粒的形核长大.

中国慈善史属于中国社会史中社会功能的重要类项。随着国内外慈善事业研究的推进,慈善史研究成果不断涌现。但中国慈善史能否成为一门独立的学科,需要有一定的理论依据。笔者认为,中国慈善史研究已有专业的学科概念、明确的研究对象、丰硕的研究成果、相应的研究队伍,以及广泛的社会需求,业已具备成为独立学科的条件。从社会史、慈善学与其他相邻学科的比较中,中国慈善史的学科知识体系更加明晰。其认识功能、实践功能和教化功能已能促使其发挥作为一门学科应有的效用。
