(CSL) boundaries which was a possible cause for improving the creep rupture resistance. The fracture surface of RE-added steel exhibited less intergranular cracks suggesting the alteration on the nature... cause for longer creep duration. These results strongly suggested that the effect of RE alloying played a crucial role in improving the creep rupture resistance.关键词:......
The Warm Deformation Treatments for Improving the Resistance of High Strength Steel Wires to Low Cycle Fatigue and Room Temperature Creep () [全文内容正在添加中] ......
MPa, the coarse-grain basketweave structure has the highest creep resistance, fine-grain equiaxed structure has the lowest creep resistance, and the duplex structure has a moderate creep resistance. After a long thermal exposure at 600 ℃, the creep resistance of basketweave structure reduces. On the contrary, the creep resistances of duplex and equiaxed structures improve, which may be due......
phases and structures are very important to those alloys for their high strength and heat-resistant stability at elevated temperatures. Key words: magnesium alloys; heat resistance; creep resistance... and their development are reviewed. Mg-Al, Mg-Zn, Mg-RE, Mg-Th, Mg-Ag system alloys, rapid solidification magnesium alloy and magnesium-based composite in heat resistance are introduced. It suggested that Mg-RE......

compared in terms of dynamic hardness, creep resistance and plasticity. The dynamic hardness of three kinds of solder decreases with increasing the penetration depth. For SAC0705BiNi/Cu, the ultimate... Bi and Ni elements, the hardness and solder creep resistance of SAC0705BiNi solder are improved, and the good plasticity is still maintained. Key words: ball grid array solder joint; creep resistance......
no element Ta are obviously decreased with the increasing of temperature. The main reason for the better creep resistance of the alloy, containing more elements Ta and Al, during steady creep is that it keeps a high volume fraction of γ′ phase.
