德国基尔大学研究人员新发明了一种镍钛铜记忆合金,其变形次数可以达到千万次不会断裂,而通常合金材料变形几千次就会断裂。这一新材料在微电子和光学器件、传感器、医疗器件等众多领域将有广泛的应用前景。科学家早在上世纪60年代就发明了镍钛记忆合金,这种合金在受热和冷却时会变形,并很快会恢复到最初机械加工时确定的形状。我们熟悉的大多数合金在两种 Researchers at the German University of Kiel invented a new nickel-titanium copper memory alloy, the number of deformation can reach ten million times without breaking, and usually alloy deformation thousands of times will break. This new material will have a wide range of applications in many fields such as microelectronics and optics, sensors, medical devices and more. As early as the 1960s, scientists invented nickel-titanium memory alloys that deform when heated and cooled and quickly return to their original shape for initial machining. Most of the alloys we are familiar with are in two
