and development of the technology using finite element (FE) modeling and simulation is of significance for manufacturing seamless ring-shaped components with high quality, low cost and short cycle. The current international level, remained problems and development trend of macro-scale and micro-scale FE modeling and simulation of hot ring rolling were reviewed, and the following prospects......
-C梯度过渡层(WCGC),采用热丝化学沉积法(HFCVD),以甲烷和氢气为反应气体,在基体表面生长金刚石膜.采用场发射扫描电子显微镜(FE-SEM),X射线衍射仪(XRD)和激光拉曼光谱(Raman)对W-C过渡层和金刚石膜进行检测分析,研究热丝辐射距离和沉积气压对WCGC与金刚石膜的的影响.结果表明:热丝辐射距离对金刚石薄膜和WCGC均有较大影响;WCGC过渡层能够在一定热丝辐射范围内降低Fe在...大挑战.WEI等[22-23]最近报道了通过W-C梯度过渡层阻碍金属粘结相Co的扩散,成功地在WC-Co硬质合金基体上沉积了高质量微米和纳米金刚石薄膜. Fe元素与Co元素对CVD金刚石生长具有十分类似的抑制作用.本文作者以高速钢为基体,采用反应磁控溅射技术在钢基上制备W-C梯度层作为中间过渡,试图利用该过渡层隔离钢基体中的Fe,从而阻碍钢基中Fe的石墨化作用和C在Fe中溶解和扩散,同时希望强碳型......
in a stationary air ambient, then SiO2 thin film was formed on the SiC structure. The SiCn/2618 composite was prepared via casting the liquid 2618 Al alloy (2.25% Cu, 1.60% Mg, 1.10% Fe, 1.15% Ni, 0.20... 25 November 2012 Abstract: The dry friction and wear behaviors of co-continuous composites SiC/Fe–40Cr against SiC/Al 2618 alloy were investigated on a ring-on-ring friction and wear tester at sliding......
alloys are widely used in the economy, particularly in the transportation, packaging and construction industries. Most aluminum melting is accomplished in large, natural-gas-fired furnaces. Although... surface. The temperature was measured by means of thermocouple NiCr-Ni and the major gas-phase species concentrations were detected by flue gas analyzer from Testo in one point at the end of the furnace......
