定向凝固提高ＮｉＡｌ基复合材料韧性蓝宝石纤维增强镍铝基复合材料由于其铝化镍基体在较低温度下的韧性和延性低，以致限制了这种材料的实际应用。为了解决这一问题，美国ＮＡＳＡＬｅｗｉｓ研究中心研究了在这种复合材料制造过程中采取区熔定向凝固处理的效果。发现Ｎｉ...
Directional solidification enhances toughness of NiAl-based composites Sapphire fiber reinforced nickel-aluminum-based composites have limited the practical application of this material due to their low toughness and ductility at lower temperatures. In order to solve this problem, NASALewis Research Center of the United States studied the effect of zone melting directional solidification during the manufacturing of this composite material. Found that Ni ...
