钛及钛合金的可焊性高纯度的钛(99.9％)强度不高,因此不能应用,目前用的是工业纯钛,含钛99.5％以下。为了改善钛的加工性能和机械性能,钛的合金化具有很大的意义。在钛合金中常加的元素有:铝、锡、锆、铬、锰、钼、钒、铁等。铝、锡、氧、氮、碳等在钛中溶解,有稳定(?)相作用,称这些元素为(?)稳定元素。钼、钒、铌、钽等在钛中溶解,有稳定β相的作用,称这些元素为β稳定元素。
Titanium and titanium alloys solderability High purity titanium (99.9%) strength is not high, so can not be applied, the current use of industrial pure titanium, titanium 99.5% or less. In order to improve the processing performance and mechanical properties of titanium, titanium alloying is of great significance. Common elements in the titanium alloy are: aluminum, tin, zirconium, chromium, manganese, molybdenum, vanadium, iron and so on. Aluminum, tin, oxygen, nitrogen, carbon and other dissolved in titanium, a stable (?) Phase, said these elements (?) Stable elements. Molybdenum, vanadium, niobium, tantalum and other dissolved in titanium, the role of a stable β-phase, said these elements are β-stable elements.
