摘要：马桥镇出土的明末蓝印花布被面图案艺术风格鲜明,与清末及民国时期的明显不同。通过对比研究其图案构成及艺术处理方法,发现马桥蓝印花布被面图案设计受同时期织花图案和绘画艺术的影响,构图和艺术表现偏重写实,较少考虑制版与刮浆工艺的合理性,其制版复杂、刮糊难度大。制版的工具主要为刻刀,防染糊黏性大,但防染效果较好。靛蓝还原染色技术已经成熟,且色牢度好。研究表明:明代中期至民国300年时间,随着制靛技术的成熟,植棉的大力推广以及棉布的普遍使用,使蓝印花布从图案设计到制作工艺不断发展、完善直至成熟。

摘要：设计了4种成分的低成本Ti-Al-V-Fe合金,通过真空非自耗电弧熔炼及热处理得到成分较为均匀的(α+β)钛合金铸锭,并利用扫描电镜、拉伸试验机、数显硬度计等手段研究了不同Fe和V含量的低成本钛合金的微观组织与力学性能。结果表明,不同成分钛合金的组织差异不明显,多为粗大柱状晶,显微组织为魏氏组织和网篮状组织;随着Fe和V含量增加,其屈服强度和抗拉强度随之增大,其中Fe比V的强化效果更明显;当Fe含量升高时,钛合金伸长率降低程度明显严重,Fe含量过高会使晶格畸变过大引起相的脆化;V对钛合金组织细化作用明显,当V含量增加时钛合金伸长率略有提高。

摘要：通过对真空非自耗电弧炉制备的Nb-16Si-22Ti-2Cr-2Al-2Hf-xFe(x=0, 1,2, 3, 5, at%) 5种铌硅合金的热变形行为进行探索和研究,分别绘制了5种铌硅合金的热加工图,并分析了不同变形参数下合金显微组织的变化,确定了各合金的最佳变形工艺范围,为后续铌硅合金的设计及热加工研究提供了理论依据。合金耗散效率因子η的最大值出现在低应变速率及高温区域;最小值则出现在低温和高应变速率区域。不同Fe含量合金的热加工图中均存在失稳变形区,主要分布区域与低耗散效率因子区重合,同时,失稳区晶粒明显拉长,晶界出现弯曲扭折现象,晶粒大小分布不均匀,发生了局部塑性流动。稳定变形区存在链状的动态再结晶组织,细小的再结晶晶粒沿晶界分布,随着变形温度的升高和应变速率的降低,动态再结晶晶粒的尺寸增大。
