. The experimental results show that the solid-liquid interface will gradually become sloping with the increase of the forced flow velocity when the thermoelectric magnetic convection(TEMC)dominates the forced......
纵向磁场对Al-40%Cu过共晶合金定向凝固显微组织的影响沈裕1,任忠鸣2,李喜3,任维丽3(1.上海市上海大学上海市钢铁冶金重点实验室2.上海大学 上海市现代冶金与材料制备重点实验室3.上海大学 上海市现代冶金与材料制备重点实验室,上海 200072)摘 要:研究了纵向磁场对Al-40%Cu(质量分数)过共晶合金定向凝固显微组织的影响.结果表明,在温度梯度GL=42.6K/cm,生长速率R=2μm/s,施加弱磁场时,Al2Cu初生相由规则小平面状逐渐变得不规则,并趋向于非小平面方式生长,热电磁对流效应在不同尺......
新疆金窝子矿床黄铁矿标型特征及其找矿意义饶东平1,曹新志1,徐伯骏1,赵明2(1.湖北省武汉市地质大学资源学院2.江汉油田)摘 要:通过对金窝子石英脉型金矿床中黄铁矿的形成世代,晶体形态及热电性进行研究,结果表明:黄铁矿的形成可划分为4个世代,其中第二和第三世代黄铁矿含量高,含金性较好;黄铁矿晶形较为简单,仅出现立方体,五角十二面体及它们组合成的聚形,矿脉由上至下,晶形的变化趋势预示矿脉向深部仍有一定的延伸;黄铁矿热电系数的测定表明本区金矿床的形成温度为中低温;各矿脉的黄铁矿热导电型多以空穴型(P型)为主,热电......
