sleeve plunge refill friction spot welding, but causes upper plate material of original lap interface extending into interior of stir zone, and as the plunge depth increases, makes it a characteristic......
and α/β phase boundaries. Extending the aging time to 24 h, excepting the silicides in the primary α and lamellar α phase, the α2 phase presents in the alloy. Extend the aging, the strength of the Ti60......
control parameters was gained. A case study was conducted to validate the proposed roll shifting strategy, reducing uncontrollable quartic loading gap contour, improving strip profile and extending rolling......
was obtained. The microstructure of stip casting sheets and heat treatments was systematically studied. The macrostructure consisted of columnar crystals extending inward and centrally located equiaxed crystals......
extending along α2 phase from lamellar interfaces in hot corrosion tested TiAl alloy was observed. However, by being coated with Si-Al-Y coating, the hot corrosion performance of TiAl alloy was improved......
ability is also decreased because of the decrease of crystal defects. However, along with the extending of the solution time, the decrease of cathode β-Mg17Al12 phase can lead to an increase......
). The results show that the whole deposition process can be divided into three stages:extending growth,transitional growth and dendritic growth. The deposition rate and morphology of Ag deposit are all......

(Ti,Al)N/Ti2AlN涂层的制备董瑜亮1,闫旭波1,赵升升1,宫骏1,孙超1(1.辽宁省沈阳市科学院金属研究所金属腐蚀与防护国家重点实验室)摘 要:利用电弧离子镀技术在不锈钢基体上沉积了Ti-Al-N涂层,研究了沉积工艺参数对沉积态涂层的成分及相组成的影响,以及在不同退火处理条件下各涂层组织的变化.XRD结果表明,通过改变沉积工艺参数可以控制沉积态涂层的成分,使涂层经退火后生成Ti2AlN相.适当成分的沉积态涂层退火生成Ti2AlN相所需的最低退火温度为650℃,其它沉积态涂层在700℃或更高温度下退火......
